Borderless vs Fullscreen: Which Is Better for FPS? (2026)

Quick answer: Yes — fullscreen exclusive still delivers more FPS than borderless windowed in most games in 2026 (typically a 2–11% gap, largest in competitive shooters on mid-range PCs), because it can bypass the Windows compositor (DWM). Borderless wins on convenience. A virtual gaming display like Staged gives you both — native fullscreen performance with your apps visible — and can even gain FPS (up to 2×, measured) by rendering fewer pixels.

The borderless vs fullscreen performance debate has been raging in gaming forums for over a decade. You've probably seen conflicting advice:

"Borderless and fullscreen are the same now, Windows fixed it in 2018!"

"Borderless kills your FPS, always use fullscreen!"

"I can't tell the difference, it's placebo!"

Who's right? After years of testing, benchmarking, and building software specifically to solve this problem, I'm going to give you the honest answer: It depends on your hardware, your game, and your Windows version—but fullscreen still wins in most cases.

Let me explain exactly what's happening under the hood, show you real-world performance data, and explain how to get native fullscreen performance without sacrificing the convenience of borderless windowed mode.

What's the Difference Between Fullscreen and Borderless?

Let's start with the technical fundamentals.

Fullscreen Exclusive Mode

When a game runs in fullscreen exclusive mode:

1. The game takes exclusive control of your display output
2. The game bypasses Windows Desktop Window Manager (DWM)
3. The GPU renders directly to the monitor without composition
4. Windows does minimal processing of the game's output
5. The game has priority access to GPU resources

Benefits:

• Lowest possible latency (input to screen)
• Highest FPS potential
• Most efficient GPU usage
• Reduced CPU overhead
• Better frame pacing in many cases

Drawbacks:

• Alt-tabbing minimizes the game (slow, can cause stuttering)
• Can't see other apps while gaming (Discord, OBS, browser)
• Some games crash or stutter when losing focus
• Multi-monitor setups can have weird behavior

Borderless Windowed Mode

When a game runs in borderless windowed mode (also called "windowed fullscreen"):

1. The game runs as a window that matches your screen resolution
2. No window borders or title bar (hence "borderless")
3. Windows DWM composites the game with your desktop
4. The game shares GPU resources with other apps
5. Everything stays rendered even when you switch apps

Benefits:

• Instant alt-tabbing (game stays running in background)
• Can see other apps while gaming (Discord, OBS, chat)
• Better multi-monitor experience
• No display mode switching when launching/exiting
• More stable for some games

Drawbacks:

• Potential performance loss (varies by system)
• Higher input latency in some cases
• DWM overhead (CPU and GPU)
• Can cause stuttering or frame pacing issues
• Triple buffering enforced by Windows

The Windows DWM Problem (And How It Changed in 2018)

The Desktop Window Manager (DWM) is Windows' compositing system that handles window rendering.

How DWM Affects Gaming

In borderless windowed mode:

• DWM composites your game window with your desktop and other windows
• This adds one or more frames of latency
• Triple buffering is forced, which can cause stuttering
• GPU has to render the desktop and other apps simultaneously
• CPU has to manage the compositing process

In fullscreen exclusive mode:

• DWM is bypassed entirely
• The game renders directly to the display
• No composition overhead
• Lower latency, higher FPS

The 2018 Windows Update (And Why It Didn't Fix Everything)

In 2018, Microsoft introduced "Fullscreen Optimizations" with Windows 10 version 1803. The goal was to make borderless windowed mode perform identically to fullscreen exclusive.

What changed:

• Windows attempts to give borderless windows exclusive GPU access
• DWM tries to reduce composition overhead for fullscreen apps
• Some latency improvements for borderless mode

What didn't change:

• Fullscreen optimizations don't work consistently across all games and hardware
• Some games still perform worse in borderless mode
• DWM overhead still exists, even if reduced
• Input latency is still measurably higher in many cases

The truth: For some games on some systems, borderless is now close to fullscreen performance. But for competitive gaming, high-refresh-rate displays, or GPU-intensive titles, fullscreen exclusive still delivers better results.

Real-World Performance: Borderless vs Fullscreen

Representative figures from community and industry testing across typical rigs — your exact numbers depend on GPU, game and settings, but the pattern is remarkably consistent.

High-End Gaming PC (e.g. RTX 4080-class, 1440p/165Hz)

Mid-Range Gaming PC (e.g. RTX 3060 Ti-class, 1080p/144Hz)

On input latency: borderless routes through the DWM compositor, which adds measurable input delay on top of the FPS cost — the penalty is smallest on high-end rigs and largest in high-refresh competitive play. (Precise millisecond deltas vary by capture method and hardware, so we don't publish single-number latency claims we haven't measured ourselves — see the measured Staged numbers below for the ones we do stand behind.)

Key Findings

1. Fullscreen always wins, but the margin varies
2. Competitive shooters see the biggest performance gap (9-11% FPS, plus a measurably higher input latency)
3. GPU-limited scenarios show smaller differences (2-5% FPS)
4. Input latency is consistently worse in borderless (measurably higher; varies by game and rig)
5. High-refresh monitors amplify the latency difference
6. Mid-range GPUs suffer more in borderless than high-end GPUs

When Borderless vs Fullscreen Actually Matters

Not every gamer needs to stress about this. Here's when it matters and when it doesn't.

When Fullscreen Matters (Use Exclusive Mode)

Competitive gaming: If you play CS2, Valorant, Apex Legends, or any game where 5ms of latency affects your performance, use fullscreen. The input lag difference is real and measurable.

High refresh rate gaming: 240Hz, 360Hz monitors demand the lowest latency possible. Borderless windowed mode's extra latency is more noticeable at high refresh rates.

GPU-limited scenarios: If your GPU is already struggling to hit 60+ FPS, borderless mode's 5-10% performance loss could drop you below smooth gameplay.

Older hardware: Mid-range or older GPUs (GTX 1660, RTX 2060, RX 5600 XT, etc.) see bigger performance gaps in borderless mode.

Frame time consistency: If you experience stuttering or inconsistent frame pacing in borderless mode, fullscreen often fixes it.

When Borderless Is Fine (Or Even Better)

Multi-monitor setups: Borderless lets you move your mouse to a second monitor without minimizing the game. If you have chat, Discord, or OBS on a second screen, borderless is convenient.

Streaming and content creation: If you need OBS, chat overlays, or other apps visible while gaming, borderless makes your workflow smoother.

High-end GPU with headroom: If your RTX 4090 is running a game at 200 FPS and you only have a 144Hz monitor, the 5-10% loss in borderless mode doesn't matter—you're still well above your refresh rate.

Casual gaming: If you're playing story-driven single-player games where reaction time doesn't matter, borderless's convenience outweighs the small performance cost.

Games with alt-tab issues: Some older games crash or stutter when minimizing from fullscreen. Borderless prevents these issues.

The Best of Both Worlds: Staged — Native Performance Plus Your Apps

Here's the real problem. You want fullscreen's performance, but you also want Discord, OBS, or your browser visible while gaming. The traditional choice is a lose-lose:

• Fullscreen exclusive: best performance, but you can't see anything else
• Borderless windowed: you see your apps, but you pay the 2–11% FPS and input-lag penalty above

Staged refuses that trade-off — and then goes one better.

How Staged flips the penalty into an FPS gain

Staged creates a real virtual gaming monitor inside your PC. Your game renders there at the resolution you choose — completely decoupled from your physical 1440p or 4K screen — and Staged shows it live in a zone on your desktop, with OBS, chat and alerts right beside it. One monitor, everything visible, no alt-tabbing.

The twist: because you pick the render resolution, you can render fewer pixels than your monitor drives — so the GPU works less and the game gets faster, not slower.

• Gain FPS while you stream — up to 2×, measured. In a same-scene A/B on the same PC, a GPU-bound scene ran 72 fps native at 1440p and 144 fps on a 1080p Staged stage — and 144 was the monitor's refresh cap, not the GPU's limit, so the true gain is even higher. Typical AAA gains at 1440p→1080p land around +30–60%. (2× is the GPU-bound best case — your mileage varies by title.)
• 44% fewer pixels to render on a 1440p monitor; 75% fewer on 4K — that's exactly where the extra frames come from.
• Zero frame lag. In 10/10 measured samples the stage showed the exact same frame as the game. The pipeline adds under 0.2 ms of processing on a direct hardware-scanout path — 0.0% compositor overhead, measured.
• No game hooks, no injection, no anti-cheat risk. Staged never touches the game process — the game just sees a normal monitor.
• Featherweight: about half a percent of a modern CPU and ~2.5% GPU while capturing at 144 Hz — dwarfed by the pixels you just stopped rendering. Full HDR support; VRR (G-Sync/FreeSync) is not available on virtual displays — a Windows limitation — you run a rock-solid fixed refresh up to 500 Hz instead.

So instead of asking "how much FPS does borderless cost me?", ask the better question: why give up FPS at all? Run your game on a Staged stage, keep OBS and chat in view, and walk away with more frames than borderless — often more than native fullscreen.

How to Optimize Fullscreen Performance

If you're committed to fullscreen mode, here are optimization tips.

Disable Fullscreen Optimizations (Sometimes)

Windows "Fullscreen Optimizations" are supposed to help, but they can cause issues in some games.

To disable:

1. Right-click the game's .exe file
2. Properties → Compatibility
3. Check "Disable fullscreen optimizations"
4. Apply

Test with and without this setting. Some games run better with it enabled, others don't. It's game-specific.

Use Exclusive Fullscreen, Not Borderless

In graphics settings, make sure you select:

• "Fullscreen" (not "Borderless Windowed" or "Windowed Fullscreen")
• Some games call it "Exclusive Fullscreen" or "Fullscreen Exclusive"

Disable V-Sync (Use G-Sync/FreeSync Instead)

V-Sync adds latency even in fullscreen mode. If you have a G-Sync or FreeSync monitor:

1. Enable G-Sync/FreeSync in your GPU control panel
2. Disable V-Sync in-game
3. Cap your FPS to 3-5 below your monitor's max refresh rate (e.g., 162 FPS for a 165Hz monitor)

This eliminates tearing without V-Sync's latency penalty.

Enable Game Mode in Windows

Windows Game Mode prioritizes gaming performance:

1. Settings → Gaming → Game Mode
2. Toggle ON

This reduces background task interference and can improve frame pacing.

Update GPU Drivers

NVIDIA and AMD regularly optimize drivers for fullscreen and borderless performance. Keep your drivers updated.

Monitor Latency with NVIDIA Reflex or AMD Anti-Lag

If your game supports NVIDIA Reflex (RTX GPUs) or AMD Anti-Lag (Radeon GPUs), enable it. These technologies reduce system latency in both fullscreen and borderless modes.

Games Where Borderless vs Fullscreen Matters Most

Some games show bigger differences than others.

Massive Difference (Use Fullscreen)

CS2, Valorant, Rainbow Six Siege: Competitive shooters where every millisecond counts. The latency difference is significant and affects gameplay.

Overwatch 2, Apex Legends: Fast-paced games with high refresh rate benefits. Fullscreen gives a competitive edge.

Fighting games (Street Fighter 6, Tekken 8): Frame-perfect inputs require the lowest latency possible.

Moderate Difference (Fullscreen Preferred, Borderless Acceptable)

Cyberpunk 2077, Starfield, Hogwarts Legacy: GPU-intensive AAA games. Fullscreen gives 5-10% better FPS, which matters if you're already GPU-limited.

Monster Hunter World, Elden Ring: Action RPGs where frame pacing matters. Fullscreen often feels smoother.

Minimal Difference (Borderless Is Fine)

Civilization VI, Cities Skylines, Factorio: Strategy games where you're not GPU-limited and latency doesn't affect gameplay.

Stardew Valley, Terraria, Hades: Indie games with low GPU requirements. The performance difference is negligible.

Turn-based RPGs (Baldur's Gate 3, Divinity Original Sin 2): Latency doesn't matter, and borderless makes alt-tabbing during long turns convenient.

The Future: Will Borderless Ever Match Fullscreen?

Microsoft has been working on this problem for years. Each Windows update brings minor improvements to DWM efficiency and fullscreen optimizations.

DirectX 12 and Vulkan improvements: Modern rendering APIs handle borderless mode better than older DirectX 11 games.

Hardware-accelerated GPU scheduling: Windows 10/11 feature that reduces latency in borderless mode (enable in Graphics Settings).

Variable Refresh Rate (VRR) support: Better integration with G-Sync/FreeSync in borderless mode.

Will they ever be identical? Probably not. The fundamental architecture of DWM composition adds overhead that fullscreen exclusive bypasses. But the gap is narrowing, especially on high-end hardware.

For now, if you want the absolute best performance, fullscreen exclusive is still king.

Frequently Asked Questions

Does fullscreen give more FPS than borderless?

Yes. In most games fullscreen exclusive delivers 2–11% higher FPS and lower input latency than borderless windowed, because it bypasses the Windows DWM compositor. The gap is biggest on mid-range GPUs, in GPU-bound titles, and at high refresh rates. The catch: fullscreen hides Discord, OBS and chat. Staged removes the trade-off — it runs your game on a real virtual monitor at the resolution you choose, so you keep your apps visible and gain FPS (up to 2×, measured) instead of losing it.

Does borderless windowed reduce FPS?

Yes, typically by 2–11% depending on the game, your GPU, and your system — GPU-intensive titles on mid-range hardware see the biggest loss, and input latency rises too. If you only go borderless to keep other apps visible, Staged gives you that visibility without the penalty: because you pick the render resolution, you can render fewer pixels and actually gain frames.

Does borderless windowed affect input lag?

Yes. Borderless routes every frame through the DWM compositor, which adds latency versus fullscreen exclusive — noticeable in competitive shooters on 144 Hz+ displays, negligible at 60 Hz. Staged takes a different path: a direct hardware-scanout pipeline with zero frame lag — in 10/10 measured samples the stage showed the exact same frame as the game (under 0.2 ms of added processing).

Is fullscreen or borderless better for streaming?

Borderless is convenient (you see OBS, chat, alerts) but costs performance. The best of both is Staged: your game runs on a virtual monitor at native fullscreen quality with OBS and chat beside it on one screen — and you gain FPS (up to 2×, measured) because you choose the render resolution. No alt-tabbing, no penalty, no anti-cheat risk.

Cyberpunk 2077: borderless or fullscreen?

Cyberpunk 2077 is GPU-heavy, so fullscreen exclusive gives a measurable FPS edge over borderless — worth it if you're GPU-limited. If you stream or want a browser/guide beside it, run it on a Staged stage: render at 1080p on your 1440p or 4K monitor for a big FPS jump with full HDR and your apps still visible (note: VRR is not available on virtual displays — a Windows limitation).

CS2: fullscreen or fullscreen windowed?

For CS2 and other competitive shooters, use fullscreen exclusive — lowest input latency and highest FPS, which matters at 144 Hz+. If you need chat or a coach's cam on screen, Staged keeps them visible with zero frame lag (same frame as the game, measured) instead of the borderless latency hit.

Does fullscreen mode increase FPS in 2026?

Yes. Despite Windows' DWM improvements, fullscreen exclusive still delivers 2–11% higher FPS and lower input latency in most games in 2026 — most noticeable in competitive shooters, on high-refresh monitors, and on mid-range GPUs. Or skip the compromise entirely: on a Staged stage you render at the resolution you choose and gain FPS (up to 2×, measured) while keeping every app in view.

Should I disable fullscreen optimizations in Windows?

It's game-specific. Some titles run better with fullscreen optimizations on, others off — so test both. Competitive players (CS2, Valorant) often disable it; modern DX12 games often prefer it on. There's no universal answer — benchmark your specific games.

What is the input lag difference between borderless and fullscreen?

Borderless windowed adds measurable input latency versus fullscreen exclusive — small at 60 Hz, but significant for 144 Hz+ competitive play, where fullscreen's lower, more consistent latency is a real edge. Staged sidesteps the question: its direct-scanout pipeline shows the exact same frame as your game in 10/10 measured samples (zero frame lag), so you get apps-on-screen convenience without a borderless-style latency tax.

Bottom line: In 2026, fullscreen exclusive mode still delivers better performance than borderless windowed mode in most scenarios. The difference ranges from negligible (~2% in casual games on high-end hardware) to significant (~11% FPS loss plus added compositor input delay in competitive games on mid-range systems).

If you want the best of both worlds—fullscreen performance with the convenience of visible apps—consider zone-based gaming with tools like Staged. You shouldn't have to choose between performance and usability.
