I just found a solution for those who have NVIDIA cards and experience a glitch that includes flash popping and texture problems.
my specs: i7 950
Nvidia GTX 480
6 gigs RAM
Windows 7 Home Premium 64 bit
If you set your display settings to ultra high, you may notice that it checks off both HDR and antialiasing. NVIDIA graphics cards apparently can't support both HDR and antialiasing at the same time, so you have to choose bloom + antialiasing
or HDR with antialiasing off. I have heard that you can force your NVIDIA gpu to run both HDR and antialiasing at the same time, but you have to set it up in the NVIDIA control panel and I have no idea what would happen if you did.
I am playing with HDR and antialiasing off, and it works pretty well.
Hope this helped.
