Hi and thanks for the replies.
@stumped 1. Amd a4 5300 - 3.4Ghz
2. HD 6570
3. Win 7 x64
4. 13.3 beta
5. The PSU is called DeLux and it's 450W
6. 6 Gb of ram
7. My computer did come with the graphics card, but I had the OS myself.
8. The monitor is an old CRT one with a max resolution of 1280x1024 and a 85 Hz refresh rate. It is connected via D-sub.
@Nevune. Yes, my PSU is 450W, which is enough for this card(or so I've read). I already installed another windows. The first one I installed was windows 8 x64 and I had the same issues, and now I installed windows 7 x64 and the issue persists. I've read on some other forums that some cards have some problems when connected via D-sub, so I might just try to go to a friend's house and test another port, because I don't have anything else to connect to my PC except my old CRT. Thanks.
EDIT: I managed to solve this problem. To anyone else who is having this problem, use a program called RadeonPro, it's basically a more advanced Catalyst Control Center. A friend recommended this for me, and it amazingly solved all my texture flashing/flickering. As far as I could tell, my problem was AA. With RadeonPro I just checked FXAA(an option that isn't present in CCC) and everything was solved just like that.
