I have a self build PC and with some high demanding games such as Call of Duty MW2, Napoleon: Total War, Crysis etc, artefacts occur.
I have done several things myself. AS a start I sent my GFX to the shop i bought it from and to the manufacterer. Both found no problems and the gfx was even tested with MW2 with all setting as high as possible.
Second I replaced my cpu cooler since the temperatures were at 68C max with the stock cooler, now its not higher then 50C, but the artefacts are still there.
So can it be something else? My thought is artefacts=display=gfx but somehow the shop and manufacterer theres nothing wrong with the card.
Hmm, artefacting is more than likely to be the GPU... try a borrowing a card off a friend and see if that works fine? If you cant... RMAing i would think..
How long have had this card and when did the problems start?
I have this problem since the beginning I build this PC. (only played world of warcraft, wich has no problems at all unless i turn shadows off), this doesnt help with other games tho). The card is almost one year old.
Already RMA'd it to evga, they found no problems with modern warfare 2 and some other tests, while I do have problems with it.
Ill try to borrow a friends gfx next week.
On a sidenote, I read there could also be something wrong with my memory or false power supply?
