Okay, the old soft shadows were really nice but destroyed my fps. This is basically just as good, and I think I lost like two frames.
However, I noticed when testing this out I was getting weird striations in the floor. Both bricks and the actual ground were affected. (click images for higher res, jpg though)
This effect is extremely minor with default shaders, almost unnoticeable, but these new soft shadows make it really nasty looking. It doesn't happen with the old soft shadows at all, though they also introduce weird artifacts of their own. Maybe I'm just being stupid and missing something here, but this doesn't seem normal. I have all my graphics settings on max, I'm running Win7 Home Premium 64 bit, Radeon R9 270X gpu, AMD FX 6350 cpu. wat do.
also woo my first toast on the forum, even though i've had the game like 5 years
