--- Comment #27 from Kai Krakow <kai at kaishome.de> ---
Well, when disabling clothing effect by removing APEX_ClothingGPU_x64.dll the
game still doesn't run any smoother. But CPU usage seems to be lower, while the
GPU keeps hovering around 45-65%. But cut scenes look overall smoother (so I'm
not sure).

Since I guess that the clothing effects are one of the major CUDA users, I
guess this is mostly unrelated to CUDA.

When neither CPU nor GPU are maxed out while the FPS are pretty low, there
seems to be a problem with synchronization of threads. Something is waiting and
it is not a busy loop (otherwise CPU would be maxed out, at least one core). So
I'm fine with not discussing CUDA issues here. But if there's another place
with CUDA related discussion for the game, I'd be interested in a link.

BTW: There are discussions of whether removing APEX_ClothingGPU_x64.dll has any
effect at all, it may be a placebo effect. For me, it seems to change some
behavior but overall performance isn't affected. Some people argue that
deleting the DLL and the game can still run only means that it wasn't used at
all. But I guess this DLL is one optional dependency and the game just falls
back to not using GPU-CUDA for clothing at all then (which it seems to use only
occasionally anyways), like it is a plugin that will be loaded if it is there.
