Search fullscreen vs borderless windowed and you will find two camps: one says borderless always adds input lag, the other says the difference disappeared years ago. Neither is quite right in 2026.
Windows 10 and 11 changed how windowed games reach the screen, and in many titles the gap is now small, yet NVIDIA still recommends exclusive fullscreen whenever possible.
This guide explains what actually happens to a frame in each mode, gives a simple decision table for ranked play, streaming with Discord open, and dual monitor setups, and walks through the Windows 11 toggle called Optimizations for windowed games, including the Auto HDR catch that stops many people from turning it off.
If you are also wondering about Game Mode, that is a separate switch covered in our Windows 11 Game Mode guide. Menu names and behavior are accurate as of November 10, 2026, and labels can vary slightly between Windows builds.
Which mode has less input lag? How each one presents frames
In exclusive fullscreen the game owns the display output and sends finished frames straight to the monitor. Borderless windowed is, literally, a window the size of your screen, so traditionally every frame passed through the Windows desktop compositor first.
That extra step is where the old rule that borderless feels a frame behind comes from.
Modern games that use the flip presentation model change the picture: when the window covers the entire screen and nothing sits on top of it, Windows can skip composition and send frames to the display with the same efficiency as exclusive fullscreen.
That is why a flip model borderless window can get effectively as close as exclusive fullscreen, with faster Alt+Tab switching as a bonus. The catch is that a notification or overlay drawn on top can push the game back into composed mode. NVIDIA is more conservative.
It acknowledges borderless latency has slightly improved but still recommends exclusive fullscreen if possible, because it bypasses the Windows compositor. Also, V-Sync On in the NVIDIA Control Panel only works for fullscreen applications, so in a window you need the in game V-Sync option instead.
The honest answer is that neither mode wins every time: results depend on the game's graphics API, your driver and your monitor. If latency is your top priority, start with fullscreen. If you live on Alt+Tab or a second monitor, choose borderless and enable the Windows 11 setting below. For pairing G-Sync or FreeSync with V-Sync, see V-Sync on or off.
Which display mode to use, by situation (as of November 10, 2026)
| Situation | Recommended mode | Why, and what to check |
|---|---|---|
| Ranked shooters where latency comes first | Exclusive fullscreen | NVIDIA recommends it when possible, and Control Panel V-Sync only applies in fullscreen. |
| You Alt+Tab to Discord or a browser a lot | Borderless windowed | Switching is fast with no resolution flicker. Turn on Optimizations for windowed games too. |
| Dual monitors with something on the second screen | Borderless windowed | Fullscreen games can minimize when you click the other monitor. For capture issues see fixing dual monitor recording. |
| DirectX 10 or 11 game played in a window | Turn on Optimizations for windowed games | The game moves to the flip model, lowering latency and enabling Auto HDR and VRR. |
| DirectX 12 game | Either mode, follow the game's own settings | DirectX 12 titles already use the flip model, so the windowed optimization is not needed. |
| G-Sync or FreeSync monitor | Test both modes in game | First confirm Windows is running your maximum refresh rate. |
| One game misbehaves after enabling the optimization | Disable it for that game only | Use Custom options for apps to switch it off per game. |
Before you settle on a display mode
- You know which display mode your game is currently using
- You checked Optimizations for windowed games under Settings > System > Display > Graphics
- You know Auto HDR switches the optimization on with it
- If you rely on NVIDIA Control Panel V-Sync, the game runs in exclusive fullscreen
- NVIDIA Reflex is on in games that support it, set up with our NVIDIA low latency mode guide
How to set your display mode and Windows 11 options
- 1Check the display mode in your gameVALORANT, League of Legends and Apex Legends all have a display or window mode option in their video settings. The wording differs between games, sometimes Windowed Fullscreen, sometimes Borderless, but any option that fills the screen with a window is borderless windowed. Note what you use today so you can compare later.
- 2Turn on Optimizations for windowed gamesGo to Start > Settings > System > Display > Graphics, open the Default settings section and switch on Optimizations for windowed games. Restart the game afterwards so it takes effect. It targets DirectX 10 and 11 games running windowed or borderless. You can see which DirectX version your PC supports with dxdiag.
- 3Know how it is tied to Auto HDRTurning on Auto HDR automatically turns on Optimizations for windowed games. If the toggle refuses to switch off, disable Auto HDR first. On the flip side, if you want Auto HDR on an HDR monitor, the optimization has to stay on.
- 4Disable it per game if something breaksIf one title flickers or becomes unstable, do not turn the feature off globally. On the same Graphics page, pick the game under Custom options for apps, select Options, switch off the optimization, save and restart the game. The same dialog lets you tick Don't use Auto HDR or, on PCs with two GPUs, choose the high performance GPU.
- 5Match V-Sync, then compare in the same sceneIf you forced V-Sync in the NVIDIA Control Panel, remember it only applies in fullscreen, so use the in game V-Sync option when windowed. Without V-Sync, frame rates above your refresh rate can tear. Then switch between modes in a repeatable spot such as the VALORANT Range or the League Practice Tool and compare frame rate and feel. To put an FPS counter on screen, follow how to show FPS in games.
Record a match in each mode and compare them side by side
Input feel is easier to judge on video than on a frame counter. DOR is a free Windows app that detects VALORANT or League of Legends when you launch it, records the whole match and collects everything in My Clips inside the app.
Switching your game from fullscreen to borderless does not require any change to your DOR recording settings. In VALORANT you also get automatic kill clips tagged for aces and clutches, and in League automatic clips for kills, multikills and objectives, so finding comparable fights takes seconds.
Record one match in fullscreen and one in borderless, then watch similar engagements back to back to decide which mode suits your hands. On supported NVIDIA graphics cards such as the RTX series, DOR records with NVENC hardware encoding. If a fullscreen recording ever comes out black, see fullscreen recording not working.
