Public bug reported: When I start a game (Surviving Mars) via Steam the framerates are abysmal, somewhere between 10 to 20 fps. On 17.4.22 it still hit 60 fps.
When my screen is attached to the 6600 XT card and the game is running, the following can be seen: jan-bart@barts-tuxbox:/sys$ cat ./devices/pci0000:00/0000:00:01.1/0000:10:00.0/0000:11:00.0/0000:12:00.0/pp_dpm_sclk 0: 500Mhz 1: 700Mhz * 2: 2900Mhz jan-bart@barts-tuxbox:/sys$ cat ./devices/pci0000:00/0000:00:08.1/0000:30:00.0/pp_dpm_sclk 0: 200Mhz 1: 700Mhz 2: 2000Mhz * jan-bart@barts-tuxbox:/sys$ lspci | grep VGA 12:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
