The % usage is not indicative of anything considering it will use as much CPU as possible to reach as high a frame rate as possible

- rowanG077 5y agoI think by default glxgears has vsync enabled. But it's trivially possible to disable it with an env var. Considering the CPU usage I assume that is what was done. 60% CPU usage for running glxgears at 120Hz seems excessive.
- e_proxus 5y agoI always remember glxgears running at hundreds of FPS and it being used as a poor man’s benchmark. Perhaps this has changed of late though…
- rowanG077 5y agoI always have had to set `vblank_mode=0` to get it to run as fast as possible.
- marcan_42 5y agoThere is no vsync with the dumb framebuffer backend I'm using. We have a real display driver, but it needs rebasing and adapting to work on these laptops (it was developed on the Mac Mini).
