I haven’t found the changes read me file yet, but they stated on the last release they would fix the known issues with PF, not that I have had any issues with the 5.1 at all with PF, but I know some have had.
Hmmm … release notes still list it as a known problem … unless the release notes are foobar … and thats happened before 
I have had mega probs with 5.1 and radeon 9800 pro.
Crosses fingers…
I have had mega probs with 5.1 and radeon 9800 pro.
I’ve been really happy with the 5.1 drivers, also with Radeon 9800 Pro… I’ll wait for a while before going to 5.2.
After a discussion with Flowbee, Ive gone back to the 4.1 drivers
and hes right , they are jolly good
these later releases just seem to make it worse.
You could try extracting just the OpenGL drivers from as many driversets as you fancy Phil and drop the dll into your main PF folder, run a benchmark - one of them will come out fastest/best eye-candy
atioglxx.dll
-or something it’s called and you can use a Dosbox to expand it and drop it in, instructions are around. Your next mission should you etc

5.2’s running tickety boo here

Got it, oohhh cant wait…
*Joe90 installs 5.2 and expects all bugs to be gone.
Set everything on default and here we go:
DOH! :mad:
So, I have now popped atiicdxx.dll in IL2 directory and so far so good, cheers Ming.
Hold on, thats not the file you said, erm, but it works for now. More testing required and I will report back.
I’m running the new DNA CAT 5.1a drivers here and have noticed significant FPS and Quality improvements over the older DNA CAT 4.12 drivers. I have them setup on 9500->9700 and the SOURCE settings. All default.
With the same settings as I usually run - Medium - Very High im getting an extra 10 or 12 FPS and its got rid of though dips down to 25 FPS down low over the trees.
Can get them from here or here.
I think the site maybe down for a while though so you can get them at Guru3D too.

After initially being very happy with the 5.2 on my 9700 pro( running 6xAA with next to no loss ), the rot soon set in. Fired up FB this afternoon to see corrupt textures in cockpit in the Beau. Looking to put the 4.7’s ( good set for me )back in after I’ve tried the 4.1’s.
I neeeeeed a new graphics card 
All is stable again.
I tried the DNA 5.1 and had problems
I put the correct 4.1 file atioglxx.dll in IL2 directory while running ATI 5.2 and had no problems. BUT, I couldnt force AA or AF.
So, took out 5.2 altogether and installed 4.1 and no problems so far (don’t you hate being right, Flowbee?)
I tried the DNA 5.1’s, was a no go, very " jerkey" graphics. 4.7’s have been my recent sweetspot, before that was the 3.7’s. 5.2 looked good initially especially in 6xTAA, however texture problems soon started to show through. 4.7’s back in now.
