Textures problems with HD4850


Dec 27, 2012
Hello there!

This is my 1st post here...
I recently switched my Nvidia Geforce 8600GTS for an Ati Radeon HD4850. Everything went well, I tried to play Team Fortress 2 and everything was fine. But when I started to play, the textures went strange. They were always like blinking, the shadows were appearing and disappearing, etc... Then I tried to play Dead Space, but the problem was the same. Since I bought this graphic card in 2nd hand, I thought it could be broken, but it isn't since there are some games working well... Then I tought the problem could be de drivers, but I know I have installed the right ones. Can someone help me please?
