Okay, so my issue is that I can play for a solid 20 minutes or so, then my screen will flicker (black,white,black for about 10 seconds).
The game will then come back up, and might run fine. If it does run fine, this will happen again in about 20 seconds to 1 minute.
When it doesn't run fine, it will run at about 0.2 FPS permanently until the game is entirely restarted (exit to desktop). Once this happens even the main menu will be extremely slow as well and it's almost impossible to click any buttons.
Restarting the client will correct the issue, but I honestly can't enjoy the game by restarting it every 10-20 minutes.
I've tried a lot of different combinations of graphics settings and nothing has fixed the issue, just prolonged it from happening.
My specs are:
OS: Windows 7 Ultimate 32-bit
Processor: AMD Athlon(tm) 64 X2 Dual Core 5200+ 2.60 GHz
Memory (RAM): 2.00GB
Graphics card: NVIDIA GeForce 8800 GTX (768 MB)
Yes, I have updated my video drivers.
