First of all, thanks for this amazing mod, this is quality
However I encountered this problem where the game slows down outdoors. Other than that, its always 60 fps. I tried changing every possible setting, lowering the resolution, even forcing max AA and AF and it doesn't make any difference in the fps. I also messed with the affinity and the compatibility settings, but no lock. Changing the renderer has also no effect.
Is there anything I might overlook? please help me, recent games run fine (using win7 64-bit)
