What sort of systems are those of you who are seeing framerate reductions using?
Edited 'cuz me no english gud.
Have yet to try the 64 client, but I have
Quad core AMD Phenom II 940
4 GB RAM
GTX 560 Ti
The game is behaving like it did when I first got my vid card 2 months ago. I initially had Directx 9 flagged. When I checked Directx 11, suddenly my fps shot up to 60 (I have it capped) and has been there until this patch. Now I get 45 if I stand still in a room. Running outside drops to <10 fps.
You may want to make a thread for your problem so a Blue can potentially help you out. As you haven't tried the 64-bit client (and thus your problems are unrelated), this thread is unlikely to be of help to you.
