37 FPS on the Black Death track. Bad?

[Skarphol]

OK, thanks for your replies.
I tried to set ProcessAffinityMask=2, and I set:
Forest=3
LandShading=3
Water=4

Then I overrided AF to just 4x. That made the graphics rather 'edgy'.
But the FPS stayed at an average of... 37! Excactly the number I had in the first place!
This is really strange, I would at least have thought that reducing the AF would have made an impact. I'll have to study this more..
