AMD Releases Catalyst 12.1 Preview - Download & Discussion

i creating those profiles and they dont working in game. OMG wha im doing wrong ?

 

Dunno, some people are saying this. You have to Apply and Save to a specific EXE per game (and the right one). If installed the 12.1's about 9times now and profiles always work if you do it as above.

 

i have 2 6870 when i am in crossfire mode i use 2gb of vram and when i desactivate the cross i just use 1 gb of vram and no stutering ! so is not a vram or ram issue i have 16gb 1600mhz dominator downlaoad msi afterburner and watch by yourself ! im french sorry for my bad english!

 

You obviously don't realise how MSI Afterburner reports RAM usage you have to divide the value by the number of GPUs so both Crossfire and a single GPU are using 1GB of RAM.

 

Its not just Afterburner of course, he isnt grasping a key limitation of Crossfire/SLI in general.

 

yes i know but still geting 2gb of total vram !!! gta 4 have same bug batman city too btf3 but play very smoot when you desac the crossfire ! whit only 1gb vram ! soo is not a number of vram problem is more the driver dispatching vram in crossfire ! noo?? i think is a lot more djob to sync 2 video card then just one !?!?

 

I installed this driver but for some reason CCC will not open. I see it running in task manager but get nothing on screen. Reinstalling the software did not help. Any suggestions? Thanks.

 

uninstall>reset>driversweeper>reset>install

 

Hmm. Didn't work.

 

The problem you describe is just generic crossfire not functioning problems. You do not have 2GB usable VRAM however, but I guess thats not relevant to the issue in this case.

 

After several weeks, the drivers FORGOT all my application profiles, and now will not save them after reboot

 

These drivers seem to be the best and no issues with any game.
