Straight Q: What's the best BF3 driver for a 7970? I've switched from a 6850 cfx to 7970 and the fps drops in BF3 are terrible. Right now I'm using fresh W7 x64 with 8.951.1 05 March (tried them all) and it's awful, I've never thought that I'll spend 500$ on a graphics card and not be able to run BF3 @ 60fps without massive drops at ultra + high. I know, my 1090T @ 4.0GHz might be a bottleneck or something, but 6850 cfx ran well at high settings with the same CPU, fps drops were so much fewer.
Am I the only one with this problem? A little bench numbers made with Fraps: Caspian Border - 64p, Conquest: min 34fps / avg 59,7fps. Keep in mind that I use vsync ON (Textures Ultra, Shadows Medium, Mesh High, HBAO, 2xMSAA (with this switched off it's almost the same thing, so ...), Motion Blur off and pretty much everything else at high.
My fps drops as hell ... any suggestions?

For BF3, 8.95.5 was the best for me BY FAR. I can run Ultra with 16xEQ MLAA at 5884x1080res in eyefinity and my fps was 100-160fps.

OFF topic. If anyone knows how to use Inventor and do things like this Render. PM me,

Its totally stable at these clocks. Run 3d mark11, unigine and played bf3 and some other games without problems.

Should I be worried about my voltage? Or is it safe for 24/7?

And another thing. With what program can i check my vram temps? And which other temps should i worry about on graphics card because I have non-OC version of sapphire 7950 and its cooler is very simplified(looks worse then coolers on card older then 3years when u take the plastic off)

I get max 82°C while playing bf3 intensively.

Check stability in Crysis 2, i could run any game with 975 Mhz core, but soon i entered Crysis 2 it crashed.

Vcore is ok I would say, I am running the same.
82 degrees is maybe abit high, with HWiNFO you can monitor vrm temps also.
Have you tried setting custom fan cooler profile? Maybe that will get your temps abit lower.
I am surprised you can run at these high settings. With 1175 core and 1580 on the memory I get driver errors while playing Batman.
Still figuring out what my max will be, but it will be lower, def. for the memory (performance is decreasing when going over 1550mhz on memory - stock voltage)

If so, if you open up the event viewer, I'd guess that you're getting errors in regard bf3 and dirt3 similar to this: 'Faulting module path: C:\Windows\syswow64\msvcrt.dll' ?
I have found if you install RC11, it toasts system files (dealing with Visual C++ I believe), and 12.2 or 8.95.5 will not function properly after--you can run atiman and driversweeper all day long, but it won't fix the issue because the RC11 driver files aren't the problem, it's what the driver _did_ that's causing fault. SFC doesn't fix it, it just complains that it cannot fix the system files in the log. Reinstalling visual C++ redists didn't fix the issue either. I have seen a few posts blaming 12.2 for dirt3 and bf3 not launching, but the issue (at least on my system) has been that RC11 was on the system at some point and changed things that atiman/drive sweeper, etc. can't fix, because it has nothing to do with the AMD driver itself, but rather, system files the AMD driver _changed_.
Just some things I have found since mucking around with these drivers. I would stay away from RC11, if you can help it. I have been doing full OS reinstalls between drivers just to isolate things, and that's what I have noticed. Just my 2cents.gif
Also, a mobo bios update seems to have fixed my install issues with 8.95.5, oddly enough.

Where be your proof that rc11 breaks the subsystems? Have you proven that you've been able to run 12.2/8.95.5 on a fresh install? It reads like this is your hunch but I'm looking for a definite conclusion in your findings and I'm not seeing it?


Hambone was on rc11 and updated to 8.95.5 w/o issues. I don't think that he's the only one to move to another driver with success from rc11. I can run 8.96, hell all of them without issues on one screen! It's when I enable eyefinity that I get crashes in dx11 games.

I don't need to prove a thing. I am simply providing some information that may be useful to someone having an issue that smells quite similar to a symptom of one that I had previously looked into a bit.

Yes, 12.2 runs after a fresh install. But once I installed RC11, any subsequent 12.2 or 8.95.5 installs did not work properly, and event logs show fault in the DLL I posted of earlier--I use eyefinity, so that's what I am testing with. Reinstalled Windows, installed 12.2, no more problems. Just providing some information, take it how you want.

Ok i just played half an hour of BF3, my core temps where max 80. My vrm temps were max 83°C.
What do u mean performance decreasing? So i'd be better of down to 1550? Or is that only at stock volt if i understood you?

That's what I wanted to know dude, because it was vague what the fix was.

Well, tsm106 pointed this out to me, that you can sometimes run high memory clocks - on stock voltage or higher voltage - but that in fact it doesnt give you any improvement in terms of FPS. And while gaming for a while it could even lead to instability. But you can check this in heaven 2.5 or 3.0 benchmarks. Try to run a different memory clock with every bench and see what the difference is (1500mhz = x FPS ; 1510mhz = x FPS ; etc...). If the increase is zero or not as much as before you should stop increasing the memory clock.
