When trying to playback a YT video in 2K on a 165hz monitor I am experiencing noticeable/constant frame dropping. Frame dropping is only present when the window is in focus, after I move my mouse to the second screen (1080p, 60hz) and click (put another window/desktop in focus) frame dropping immediately stops.
I am using Brave version 1.38.117 Chromium 101.0.4951.67.
I tried disabling hardware acceleration, and fiddling with different flag options with no luck, also I suspected the refresh rate difference between two screens I have (165hz and 60hz) but even lowering my main display refresh rate down to 60hz did not help!
Disabling Hardware acceleration will cause more stutters on youtube videos. Should only be used for lower end hardware or integrated gpu’s. Would update the GPU drivers as a start. Which GPU are you using?
No changes between Chrome and Brave regarding GPU acceleration/video playback. The only notable difference would be block of youtube ads.
Test on one screen only, disable video playback on the 2nd. Does it perform okay in 1080p? Then go from there as your baseline. Increase the primary screen to 1440p, monitoring performance. I’m assuming Hardware Accelletion is enabled.
