Bugged OpenGL at Melee with ATI x1950 Pro at 4460

[Shalafi]

Hi, I've been using Dolphin since long ago, but at some point it stopped supporting my GPU at Melee(or it looks like). I can play Brawl and Wind Waker almost fine. It happens with both PAL and NTSC versions.

I have no problems with 2195 build, but all builds newer than that show some bugs.

The first problem is the black terrain. It seems okay for the first second of a match, but when it loads shadows, they're reversed (all places where there shouldn't be shadows have them and vice-versa). This doesn't slow down the game. The Zelda TW Bloom Hack fixes it.

The second, and worse, only shows on builds 3972 and 4460. Some items (Like the capsules or cars from Onett) are blacked out and the game suffers a drop of FPS when they appear, even if they don't show. I haven't found a fix for this.

My specs:

C2D E6750@2.66GHZ
2x1GB DDR667
Ati Randeon x1950 Pro 512MB with Catalyst 8.8 (it happens with 9.8, Omega and all others I tried with).
Windows XP Pro 32 Bits SP3

Do you have EFB copy enabled?

[Shalafi]

Yes I do. After reading your post I tried the three possibilities (Disabled, to system, to GL texture) and they don't make a difference.

Thanks for the suggestion though. Btw, I know it's not a texture problem because disabling textures doesn't solve the slowdown with the capsules. It looks like a shadow problem, but disabling Material Lightning doesn't help either...
