glxgears showing 36FPS when it should be 60FPS I believe

[bridadan]

I saw this on my Pinephone as well. Turns out glxgears limits its FPS to the screen's vertical refresh rate by default. If you run the command like this you should see better FPS:

Code:

vblank_mode=0 glxgears

Here are the numbers I saw running Manjaro Alpha 3:

Code:

$ vblank_mode=0 DISPLAY=:0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.
2254 frames in 5.0 seconds = 450.721 FPS
2385 frames in 5.0 seconds = 476.996 FPS
2383 frames in 5.0 seconds = 476.464 FPS

$ vblank_mode=0 DISPLAY=:0 glxgears -fullscreen
ATTENTION: default value of option vblank_mode overridden by environment.
999 frames in 5.0 seconds = 199.058 FPS
1020 frames in 5.0 seconds = 203.997 FPS
