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/pci:00/:00:01.1/:10:00.0/:11:00.0/:12:00.0/pp_dpm_sclk
0: 500Mhz
1: 700Mhz *
2: 2900Mhz
jan-bart@barts-tuxbox:/sys$ cat
./devices/pci:00/:00:08.1/:30:00.0/pp_dpm_sclk
0: 200Mhz

2: 2000Mhz *

For some reason the clock of the unused graphics device is increased.
