power management:

After ten minutes playing at 70-80 fps the cpu seems to lag.
It's unplayable for me. Unless upgrading processor.
Somebody can confirm that my processor is not sufficient for vdrift?
Or maybe can help me with configuration to run it ok?

vdrift uses 99 percent of cpu even while not playing (i.e. settings screen).
That make me think it's s lag of vdrift rather then cpu scarcity

Those specs are fine. VDrift will always take as much CPU as possible because it wants to run with the highest framerate possible. Try setting the texture size to a lower setting (maybe medium) and see if that fixes the problem. That's the only setting that I can imagine would cause the game to run really well (70-80 FPS is very fast) for a while and then slow down. Otherwise, check your background processes. It could be that firefox or some daemon process (mysql, updatedb, etc) is causing the problem.
