I have to say the patch has made no noticeable difference on my system. I still get playable framerates running at 1680 x 1050 with
Mirror: off
Model detail: high
Building detail : very low
Land detail: low
Visual effects: high
Damage decals: high
Building amount: low
Land shadow: low
Grass: off / Shadows: on / Roads: off
I still get some stutters in the midst of a furball (6v6) when lots of guns and hits are happening. When i turn any of my settings higher the fps drops sharply, same as before.
BTW- i'm still loving it, same as before
