Interesting GPU/CPU Usage

An i7 or fast i5 is more than enough. Heck, even when I underclock my cpu to 2.8 Ghz it still runs pretty good.

It's just the buggy 3d mode (full, pseudo..) and gpu clock speed that worries me. Sometimes the game starts and my vid card stays at 157 Mhz no matter what. I shut it down and change to pseudo, and all of a sudden the vid card is now at 850 Mhz. Next time, nothing has changed in between, it's back at 400 Mhz and sometimes even back to 157 Mhz.

This is really weird game behavior which is a bit unexpected.

Yep, but this is a driver bug, you can't blame devs for this

It is? AMD is aware of this bug and 1C raised it to AMD or is it because the game does not really enter 3d mode?

What do you mean by "the game does not really enter 3d mode"?

Is the driver that has to set the graphics card in "3d mode" when an heavy task is detected, NVIDIA's cards does not have this problem.

Well, I mean real full screen. Not a stretched window or something else.

It doesn't matter if it's full-screen, windowed or pseudo, this is not the way drivers recognize a workload that require a "full performance" state, there are many graphics app that can run windowed, including most of the flight simulators

Nevermind, I completely removed 11.8 and installed Ati 11.9 and now the clocks go to maximum speed. For me, 11.9 seemed to have fixed it.
