So recently there was a sale at a hardware parts store in my village, and I came across a sealed XFX HD 7990. When I came home I immidiatly used the amd cleanup utility to clean the drivers from my previous card (r9 290) after a reboot I inserted my HD 7990 while the system was powered off. When turned on everything worked fine, so I used the amd auto detect utility to install the latest drivers. But when I tried to play some games they just didn't want to work..
Team fortress 2: I get 2-10 fps in the main menu which makes it impossible to adjust the settings.
Minecraft: Immidiatly crashes..
GTA V: Worked but it would give me a pink static screen effect.
Left4dead2: wouldn't even start....
Battlemage lichdom: Immidiatly crashed after loading the menu.
After all this I've reïnstalled the crimson drivers again, manually this team to the latest full version. I even disabled crossfire to see if that might be the problem but same results. But the weirdest thing of all is that a program like Heaven benchmark worked perfectly fine, I even had a stunning fps of 150 average...
I haven't gotten time to install the CD drivers since I don't have a CD-drive, but I don't want to use these... They're very old.
