Reason why Cat 6.2 is so slow, do you have a DFI or CF MB?

I'll get straight to the point. I've finally isolated the problem with the CAT 6.2 drivers. It's with one file, the D3D driver aka ati3duag.dl_ in an install package, and named ati3duag.dll once it's properly installed in your /windows/system32/ directory.

Catalyst 5.13 reported normal test scores in 3dMark and cpu limited games, and CAT 6.2 showed a marked decrease. Understanding this, I decided to set out and find the exact file causing the issue. First I ran both sets of drivers without CCC installed and had the same results: the cat 6.2's were eating up 20-30% extra processing compared to the 5.13 drivers. Understanding it was not a CCC issues, nor a CAT AI issue etc, I decided to see if there was something else causing the problem. So I ran 69 tests in a row...Crossfire-based motherboards (maybe only Asus A8R-MVP owners, since I've yet to see data from any DFI owners) are affected.

has anyone tried the drivers to see if you notice a bump in frame rate?

With the 6.2 drivers with all eye-candy turned on the shadows in BF2 looks horrible - does anybody else have this problem? It is not a heat issue.

It has been determined that for whatever reason it only depends on the ground surface you are on. If you go from grass to asphalt it changes... Someone pointed that out in the EA UK Forums and sure enough it was true. Just take a jeep and drive around (20' radius) and see for yourself. On grass one minute it looks like a jagged edge knife the next on the sand it's as smooth as silk (for example).

Eastcoasthandle:

I see, thank you. I couldn't find the correct phrase for it but what you just said is what I should have explained; it does look like a jagged edge of a knife, horrible.
I wonder if this can be fixed, though...

i have a similar shadow problem with everything on very high for age of empires

works fine when i drop it down to "high" though...looks far better than on very high anyways :p:

has anyone tried the mixed drivers and run a 05 or 06 3d Mark to see if it improved frame rates?

I only tried it on 01 on my windows 2000 drive....... scores went down from the regular 6.2 cats.

I noticed a lot of weird things with my xtx, in 3dmark05 the "loading" screen looks very low quality along with the Windows XP loading/progress screen when booting. I havent had enough time to test games. Im already hoping for new drivers though I have crashed about 10 times in less then 48 hours.

I recently aquired an Opteron 146, and I benched 3DMark01 @ 3070Mhz and my X1800XT @ 747/900...I only got like 400pts more than with my X2 @ 2750! The Lobby (high detail) had literally HALF the frame rate...I can't figure it out. Maybe it's this problem they're speaking of.

There are 3 different ones...the best ones so far are the 6.2/6.1 D3D Mix Driver. Has anyone tried this yet?

Ive got the same thing when mipmap is set to performance al the way in 3D06. One step up towards quality and loading screen is fine again.
