I'm still using the stock drivers for the 7970, the first ones that came out. Have newer revisions been released that are worth it? I'm asking primarily in regards to BF3 performance. Are they any better or should I just stay with these?

What settings is everyone running bf3 at? With a single 7970, I find you can only really run ULTRA>no aa>8x texture filtering or 2x aa on some maps if you want it REALLY smooth. Sure, Ultra 4x AA 16x anisotropic is playable, but it has some slowdowns sometimes which can be annoying, so I leave it off. It has to be rock solid for me. Would it be better to run everything on high and pump aa from there? Anyway, let me know if anyones played around with it

With my card running at 1280/6200 1250mV and with the first driver revision I find that at 1080p Ultra with 4xAA is fine now on all maps, except Gulf of Oman, which needs to be x2 to not feel any slowdown.

I feel slowdown on BF3 when FPS drops below 50fps, but for everyone i guess this is dfifferent.

With my card at stock clocks there was no difference in playable settings over my old 580 3GB. (which was generally x2 AA only for most maps)

Its only when these 7XXX cards are oc'd that they come to life.

4) Move the BIOS switch to the unprotected BIOS position with the system running
5) Flash the unprotected BIOS with 7970.bin: atiflash -p 0 7970.bin -f
6) Reboot
7) + rep Levesque. smile.gif

First off, thanks for your tip, and I don't need it anymore. Actually my card is fine, the reason that it shows artifacts even at stock is because the switch.

Just now I switched it to protected bios and run benchmark, and it run without any problem, then I switched it back to the unprotected bios, it worked like a charm too. The switch was somewhat lost and this's the reason why weird things happened, really speechless when I figured out the problem lol. biggrin.gif

1700 is 6800 effective. So he's at 1550.

Yeah as stated 1550mhz is 6200 effective.

If you need 70fps min you probably need to lower settings as you said earlier or go X-Fire !!!

Ps off topic but have you tried an fps limiter ? Makes the game smoother for me if i limit to my monitors refresh rate of 60

Anyone else have DX11 problems with BF3?
Even after 2 fresh installs of W7 I get them... So annyoing...
It seems like it mostly come when I try 2 change video settings.

Oh and its that RAM error I get tongue.gif It says something like I need a 500mb ++ GPU or something^^
post #3989 of 38701
I'm using 8.921.2 RC11 and latest 12.1 cap 2 for my crossfire 2 7970, but for some reason BF3 runs like crap, both cards only manage to run 50-60% usage, sluggish and stuttering. I run in single card mode, it's so smooth even it's only run about 60 fps. Am I screwed up something or simply crossfire problem?

I got that error yesterday, first Time I've gotten it. were like "Wut?"

Also got screen flickering, where my computer freezes, screen goes off after about 20 seconds, comes back I can move for 5 seconds, goes off again after 20 seconds and after 5-6 times of that I get control of my computer back...

Cmon AMD, get a new driver out already...
