Graphic glitches ><

Over the past few weeks I've had a bunch of glitches in the game.
I'm currently using a Radeon 9700 pro. I had a Geforce 660GT but my computer would keep crashing :/ All these glitches are being to annoy me.

I took a few screenies of some of glitches ><;;

you have a very messed up video card

If you haven't got any advice or ideas that might help, don't bother posting.

ok advice: get a better video card

It looks like one of thise weird colourful hallucinations

first of all, check if you didn't roast anything on the card.

as long as the card is still ok (hardware) you won't have to buy a new card, i used to play GW with a radeon 9100 and everything ran fine.

you probably have corrupted/old/bad drivers.
what you do is download the latest Catalyst drivers for your card from http://www.ati.com/products/catalyst/

DO NOT INSTALL RIGHT AWAY but save the exe to your desktop or so

now download and install Driver Cleaner ( http://www.drivercleaner.net/ ) and do exactly what it says in the manual.

seeing you have had both Nvidia and ATI cards installed, i suggest cleaning for both Nvidia and ATI drivers.

after running the cleaners install the Catalyst drivers you downloaded.

after that, reboot, and hook i-net back on (you'll notice it states in the driver cleaner manual you have to unplug your connection cable before running it all)

hope that solves the problems
