Can't get my dual graphics cards to work
I can't get my new computer running 2 x 512MB Visiontek Radeon HD 4850 GDDR3 in CrossFire™ to work properly. My acid test for graphics cards is still trying to run Quake4. I tried it at "High" setting and it starts fine but eventually crashes about a minute into the intro movie. I get a dialog box saying that something called "VPU recovery" has changed my accelerator settings to keep my computer from crashing. That's great, except it then keeps happening at regular intervals, making for a poor gaming experience. Is there something I'm doing wrong with this new setup?
I also tried running the game in medium and low quality settings....same result.
My understanding when I bought this compuiter (from reviesws) was that it should be good enough to play gam,es as demanding as Crysis, but I can't even get old Quake 4 running. Any idea what might be up?

1. Turn all of your 3D settings to 4x.
2. Go to BIOS and turn your AGP aperture size to 256 MB
3. Increase the virtual memory size to the double of the physical system memory (set it to 1024 MB in case of 512 MB system memory, Control Panel \ System \ Advanced \ Performance - Settings \ Advanced \ Virtual Memory - Change, select the hard drive, choose Custom, and enter into both fields 1024, then Set, OK and reboot)
4. Lower the hardware acceleration in Windows with one stop (Control Panel \ Display \ Settings \ Advanced \ Troubleshoot \ Hardware Acceleration).
If you still not be able to fix it, I suggest you to go to this site http://www.foxpop.com/imre/2005/vpurecover/vpurecover.html
Yuo might want to use ATI's driver too.
