Hi,

I need some help for people who spectate this list and use Wine mostly for
gaming.

In the past weeks, I have improved our ARB shader backend to support Shader
Model 3.0 on cards that support GL_NV_vertex_program3 and
GL_NV_fragment_program2(Geforce 6+), and 2.0 on other cards that have support
for the needed shader constants(ATI Radeon 9500+, intel chips).

What is this good for:

*) Works better on platforms with bad GLSL support, like Macs and Mesa
*) Deal with some corner cases, like texldd support on dx9 nvidia cards
*) Slightly better performance in some games

However, GLSL is the default right now, and we don't want to change this
anytime soon, but I'd still like to get some testing of the ARB code. So I'd
be happy if some people could disable
GLSL(HKEY_CURRENT_USER/Software/Wine/Direct3D/UseGLSL="disabled") and see how
their games work?

In the ideal world, the results are like this:
*) Everything that works with GLSL works with ARB on NV cards
*) The ARB backend is slightly faster(I've seen approx. +10%)

Can you test your games, and if something does not work that works with GLSL
file a bug and assign it to me? Also please file a bug if there is a
noticeable performance loss, or if ARB is MUCH faster(hints towards a GLSL
shader code bug). If the game runs just fine, feel free to reply to this mail
with your results and GLSL performance comparisons.

Note that ATI cards do not support SM 3.0 with ARB. This is NOT a bug. Those
cards just don't have any extensions that provide the additional features
with ARB shaders, so you have to use GLSL there if you need SM 3.0.

Thanks for your help,
Stefan
