I recently got a Radeon HD 2400 Pro, and tried it on the latest daily of Ubuntu 14.04 (as of maybe two days ago). The game I tried on it (StepMania) ran pretty badly seemingly (not going above 60; randomly staying at 30 FPS at times).
This happened on both Ubuntu with Unity, and Xubuntu with and without desktop compositing. I've even tried running StepMania with vblank_mode=0 to no avail, and vsync was disabled in-game. I've tried it with the included 3.13 kernel, and latest daily kernel too, and with radeon.dpm=1 (although if I checked the logs correctly, it would seem all the clock states are the same, making dpm useless?).
Under Windows, StepMania gets about 100 FPS with both the OpenGL and Direct3D renderer. I believe glxgears had a framerate of around 1500 (if that means anything).
I'd rather have Linux on the computer, but I need StepMania to have the best performance possible. Is there anything I could do or maybe overlooked to have better performance with StepMania?
