Do you have any experience if this actually improves things on Windows (not ChromeOS)?
AFAIK DWM is the main culprit here (1-2 frames) and `desynchronized` does not circumvent it (but avoids at best 1 frame of canvas vs DOM synchronization).

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.

edit: to answer my own question, it looks like Chrome does not use exclusive fullscreen https://news.ycombinator.com/item?id=28784108
