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 :(

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.

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

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 :)

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.

Hi,

behavior seems strange to me 

can you provide me output of gxlinfo

FYI, here is the code in question:

The function where pixelFormat is initialized is GLW_ChoosePixelFormat.

Hi,

the Q2E output from wine-0.9.2

wglGetPixelFormatAttribivARB unexpected RenderType(100)

[Toan T Nguyen]

Hi,

I compile and run Quake2Evolved in linux using winelib. Although every
seems fine, there's this error printed out when Q2E scans for the best
pixel format:

 err:opengl:wglGetPixelFormatAttribivARB unexpected RenderType(100)

I look up my /usr/include/GL/glxATI.h and found these lines:

#ifndef GLX_ATI_pixel_format_float
#define GLX_ATI_pixel_format_float  1

#define GLX_RGBA_FLOAT_ATI_BIT  0x0100

#endif // GLX_ATI_pixel_format_float


Bests,

Toan
