Fullscreen vs Borderless vs Windowed: Which Is Best for Gaming?
Published
On this page
Display mode is a one-click setting with a real latency consequence. The short version: fullscreen for competitive, borderless for convenience — but the details have changed over recent Windows versions, so here’s the current state of play.
Exclusive fullscreen hands the GPU one job: your game.
The three modes
| Mode | Latency | Alt-tab | Multi-monitor friendliness |
|---|---|---|---|
| Exclusive Fullscreen | Lowest | Slow (mode switch) | Cursor can be locked in |
| Borderless Windowed | Slightly higher | Instant | Excellent |
| Windowed | Highest | Instant | N/A — don’t game in it |
Why fullscreen is faster
In exclusive fullscreen, the game presents frames directly to the display, bypassing the Desktop Window Manager (DWM) — Windows’ compositor. In borderless, DWM composites your game with everything else on screen, which historically added up to a frame of latency and forced V-Sync-like behavior.
The modern nuance: Windows 10/11’s fullscreen optimizations and newer presentation modes (independent flip) let borderless games achieve near-exclusive performance — when conditions are right (no overlapping windows, no odd overlays). “When conditions are right” is the catch; exclusive fullscreen doesn’t depend on conditions.
Recommendations by player type
Competitive FPS player: Exclusive Fullscreen, always. Combine with Reflex and a frame cap and proper VRR setup. You’re optimizing for the worst case, and fullscreen has no bad cases.
Streamer / second-monitor user: Borderless is legitimate — instant alt-tab and smooth OBS window capture often outweigh a few ms. Mitigate the cost: close overlapping windows, keep Game DVR off, and check our OBS guide.
Single-player at high settings: Either. Borderless convenience wins; latency barely matters versus a boss that telegraphs for half a second.
Troubleshooting mode weirdness
- Game says fullscreen but alt-tabs instantly: fullscreen optimizations are active. If performance feels off: right-click the game’s
.exe→ Properties → Compatibility → Disable fullscreen optimizations, then retest. - Tearing only in borderless: mixed-refresh multi-monitor issue — see screen tearing fixes.
- Stretched res users: exclusive fullscreen is usually required for proper stretched resolution scaling.
Measure instead of debating
This argument has raged in every game forum for a decade. End it on your own system: measure your input lag in both modes with the same scene and settings. Whichever is lower on your setup wins — and while you’re measuring, Tier1Timer will tell you what the rest of your latency chain looks like.

Frequently asked questions
Does fullscreen really have less input lag than borderless?
Classically yes: exclusive fullscreen bypasses the Windows compositor, saving roughly a frame of latency. On Windows 11 with modern flip optimizations the gap has narrowed, but fullscreen remains the safe competitive default.
Why do pros use fullscreen instead of borderless?
Lowest possible latency, no compositor involvement, and nothing else grabbing focus or GPU time. The slower alt-tab is a price they accept for consistency.
Is borderless windowed bad for FPS?
Slightly, in some games — the desktop compositor stays active and other windows keep rendering. The bigger cost is latency rather than raw FPS.
What is fullscreen optimizations in Windows?
A Windows feature that runs 'fullscreen' games in an optimized borderless-like mode for faster alt-tab while trying to keep exclusive-mode performance. If a game feels off, try disabling it for that game's exe.
