Hello, I've recently bought keyclone and started tri-boxing, there's not enough words to describe how much I enjoy it, but the last time I've been playing WoW on my 3 accs, the screen has started to mess up. It starts to happend when I enter areas with alot of stuff in it, like towns and cities. I got the graphic lowest on all three wows. Turned of all sound aswell.

See for yourself: [img=http://img120.imageshack.us/img120/3457/wierdmb3.th.jpg]
There is 3 wows running.

Anyone got any clues what's wrong?
I'm using: Nvidia Geforce 8500 GT
Proc: AMD Athlon(tm) 64 X2 Dual Core Processor 4000+, MMX, 3DNow (2 CPUs), ~2.1GHz

If more info is needed, please tell me and I'll respond ASAP.
