Moving Textures

[Kill_the_Bug]

Putting this hear because I'm not sure it's an actual mapping question.

Just installed Win 7 64 bit and have a monitor and a GeForce 560GTX Afterburner card.

Game LOOKS Fantastic! However, when I'm running around or moving the walls especially will shimmer in places (more near the outside) instead of the center - it looks like the 'you have 2 brushes with two different textures occupying the same place.

Any ideas on how I should try to fix it?

investigate graphics drivers, all cable connections, lastly check your powersupply is actually capable of powering your card/isn't failing
