I have GeForce 9500M GS on my laptop and I've been having performance problems with things like CUDA, PhysX, VLC player and Flash acceleration since driver version 263.06.
For example 1920x1080 videos on Youtube look like a slideshow with newer drivers and are much slower when hardware acceleration is enabled compared to just CPU. On drivers 263.06 and older, everything works fine, so the speed of the card itself isn't the problem. The card performance in games seems to be fine.
I'm running windows 7 64bit with SP1.
So how do I solve this problem?
