Hi

Interesting and fun extension :) 
Try attached patch if it works (and it should) forward it to wine-patches

Hi,

Unfortunately, now Q2E cannot detects any valid pixel format. Here is
the Q2E output from wine-0.9.2

I can send you the source file of Q2E where OpenGL is initialized if you want.

FYI, here is the code in question:

http://cvs.sourceforge.net/viewcvs.py/q2e/q2e/source/win32/glw_win.c?rev=1.1...

The function where pixelFormat is initialized is GLW_ChoosePixelFormat.

Hi,

behavior seems strange to me

can you provide me output of gxlinfo 
and output of (using patch)
WINEDEBUG="+opengl" q2....

Thx

Can you retry with this patch ?

Thx

[Toan T Nguyen]

Thanks very much. It works. There's a small probelm worth mentioning
however: Q2E requires 32 color bits, 24bits depth, 8bits stencils. The
ATI binary driver supports 24bits only. In wine-0.9.2, somehow
wglGetPixelFormat returns 32 color bits but the current patch returns
24 only. I easily modified q2e to accept both 24bits and 32bits in
Linux. Other programs might not be happy.

WGL_COLOR_BITS_ARB cannot be 32 (was a bug i have corrected recently)
see http://www.nvidia.com/dev_content/nvopenglspecs/WGL_ARB_pixel_format.txt

WGL_COLOR_BITS_ARB
   *     The number of color bitplanes in each color buffer. For RGBA
   *     pixel types, it is the size of the color buffer, excluding the
   *     alpha bitplanes. For color-index pixels, it is the size of the
   *     color index buffer.

So for 32 bits FBConfig, it should be 24 (8 bits per RGB channels) + 8 for 
Alpha channel

If Q2E expect 32 bits for WGL_COLOR_BITS_ARB its a bug :)

And 24 bits limitation is a X limitation (X display cannot support 
alpha-channel) not an ATI limitation. 
Anyway, 24 bits displays usually support 32 bits using GLX :)

Hi, thanks for the clarification. Everything is fine then. Thank you
for the patch.

BTW, do you know how to improve OpenGL performance in wine? I get
about 10-30% drop in FPS compared to the Windows version (the card is
overclocked about 10% both in CPU and memory frequencies in windows,
so that might explains some of the performance drop). I set UseDGA to
Y in "wine regedit" but that doesn't seem to help at all.

Thanks again,
Toan

There are many factors
* Overclocking, as you  mentioned
* Speed of the 3D driver.
* Resource usage of background processen
* Overhead of Wine of course, but that should be minimal for OpenGL.
* and many more

The UseDGA has no influence on this, this affects only 2D acceleration of 
DirectDraw games.

10-30% is not wine overhead (as wine overhead for opengl is very small)
i think it's a driver problem: no linux graphic drivers have the maturity andd 
performances of windows drivers :(
