This is a message for Pete!
Pete, is there a way to let the alpha multipass function in your OpenGL driver work like the one for D3D? I don't like the big black triangles that appear with some objects on the screen. (GT2: tachometer; Dragon Ball Final Bout: the town wallpaper;...)

NB: I'm using the OGL driver because it's faster with my video card.

Sure it is possible... as a matter of fact, it already does the AM job exactly like
the D3D ones ;)

If you get different results, well, blame ATI :)

In Pete's OpenGL, this problem usually passes in color depth of 16 bit, not in 32 bit :)
This problem doesn't pass with the plugin d3d in 16bit, but OpenGL is the best :cool:
Anyway, who wants to play in color depht of 16bit these days? :D

Plugin: Pete's OpenGL Driver 1.1.50

Resolution/Color:
- 800x600 Fullscreen - Desktop changing [32 Bit]

Textures:
- R8G8A8A8

I'm using driver 4.13.7078.
I can't play in 32 bit because it will not be fast with my card, even in 640x480!

When I change to color depth of 16bit, the difference in the speed is very small, and only some games are benefitted for this reason (Parasite Eve 2 for example) in these games, I win at least 7 or 10fps more in color depth of 16bit, the difference of quality between 16bit and 32bit, in many aspects, is very remarkable, so I always play in color depth of 32bit :cool:

I know now why it is so!
Certain combinations of texture settings, alpha multipass and filtering give sometimes bad results.
I'm using 4444 textures now (was 5551) and I don't have the problem anymore (that's why pete says: bad transparency, I understand now!).
Depending on the game, one can use standard or extended filtering to remove the last glitches!
