ATI Gallium3D + Wine Is Bettered A Bit

[V!NCENT]

Actually I think stabilizing the current level of support (OpenGL 2.1) and improving performance is more important than full support for OpenGL 4.0 on paper.

I disagree. Performance is improving anyway. Linux/BSD/Haiku need to be on the forfront of technology in order to stand above of Mac OS X and Windows in way or the other. Literaly last time I checked, Snow Leopart still had OpenGL 2.1. Imagine your favo OS is graphicaly more advanced than the Mac...

I don't see how that's even an actual choice. Gallium3D moves us toward a lot more than "OpenGL 4.0 on paper". Stability should improve with better factoring of GPU driver vs. memory management vs. API code. Performance should improve as these components are optimized. We probably could have had better performance today if everyone was still hacking at classic Mesa drivers, but then we'd probably have been stuck there for another 5 years, watching GPUs and games/apps advance while we sit around comparing Doom 3 framerates.

IMO it's Wine's fault; since when is it good behavior of an app to depend on a particular compiler optimization?

you should compare amount and type of bugs reported with wine+nvidia blob to bugs reported on wine+mesa. and compare wine compatibility when running different graphics hardware.

it's not a surprise that wine works better with nvidia driver or catalyst. the driver issue is very important here.

I've got R500 and Fedora 14 installed (Gallium 0.4, Mesa 7.9). When I type glxinfo in terminal, there isn't any GL_ARB_depth_clamp listed.

Here http://www.mesa3d.org/relnotes-7.9.html It is mentioned that

GL_ARB_depth_clamp and GL_NV_depth_clamp extensions (in nv50 and r600 Gallium drivers)

So there is nothing about r300.

Does anybody have GL_ARB_depth_clamp available on his R500 hardware?

We had to disable it because it caused issues.

Thanks for reliable answer. I hope you developers will enable it again soon.

If you talk about S3TC then there is small piece of code to compile which adds support for texture compression.

[NSLW]

is there a howto to activate the s3tc support ???

It isn't complicated:
1) unpack libtxc_dxtn070518 archive from http://cgit.freedesktop.org/~cbrill/libtxc_dxtn/
2) type "make" in terminal
3) if building is successful type "make install"
4) reboot

Take heed that there's some additional work if you're on a 64bit machine and want to install that as a 32bit library.

You wouldn't happen to have those steps? I tried looking but didn't find a good writeup.
