I had a lousy MX440 AGP 64MB and everything except fps was ok, and then I put the 256MB X1650 ATI.
I entered World of Warcraft and Crossfire, and the graphics was f'd up completely. The ship was invisible, the only thing I was able to see was the lights on structures and ships (even my ship is invisible) and the planets. Not even asteroids, and the details of the universe was like in lowest detail (of the things that were visible^^).
I tried reinstalling the games, but no effect, even tried vanilla FL, same thing.
Then I thought "Hey, maybe a new Windows will solve the problem" so I installed and formatted everything. I didn't even install sound drivers or antiviruses or any drivers whatsoever, just to try if Crossfire is normal again. I got a "no sound detected" warning, but I checked "Ignore" and started the game. It worked normally!
Today afternoon, I was upgrading my Windows with anti-s and programmes and drivers, and after that I started CF again and it was f'd up again!!
HELP!
P.S. My first upgrade made on this version on Windows today was the driver for the better video card that is in atm, and it worked after that. SO the problem seems to be in something else messing up my graphics. My desktop graphics is perfectly normal btw. Only in-game sth is really freaky.
