Performance problems after combat?

[preifx]

I have that problem too!
I hate those dogs and I'd like to find a "dead dogs patch"!!
Before I see the dog, I have very smooth FPS, but if a dog appears, the FPS drops down to about 10, and if the dog attacks, I can only kill the dog according to the sound because the FPS is even fewer than 1(may be 0.5), I can only look at a static picture, hold down the left mouse button, shake my mouse, and wait to see if I'm lucky - the dog's dead(normally it couldn't be killed, but I killed it once).
I'm absolutely sure this is a TERRIBLE bug...

Does this solve it

Thanks Thomas, I'll give it a try. I didn't see any strange problems in other games with the 93.71 driver...
