On Windows it's a modest improvement, as you saw. We would need to bypass DWM to do better, e.g. with a hardware overlay.

- jd3 5y agoIt's been a long time since I used Chrome on Windows — do you know if Chrome's fullscreen mode leverages exclusive fullscreen/fse/fullscreen optimizations[0]? I'm pretty sure that's what most games use to bypass the forced DWM vsync. For example, when I used Dolphin on one of those cheap 60hz IPS LCD monitors with no internal scaler, I always preferred the lower latency + tearing in exclusive fullscreen compared to the laggy + smooth windowed mode. There was honestly such a stark difference between the two that I found the game to be unplayable in DWM's windowed vsync mode.
