S3TC Texture Compression on Intel 945
Hello,
I am using Ubuntu 9.10 on EEE PC 901, with experimental Intel drivers from xorg-edgers ( https://launchpad.net/~xorg-edgers/+archive/ppa/+packages ). In my country (Finland), using the open-source S3TC texture compression extension for Mesa ( http://www.t2-project.org/packages/7.0/libtxc-dxtn.html ) is legal. I therefore have shaders and texture compression, which work well for example in Spring RTS ( http://springrts.com/ ).
My opengl info also reports that these are enabled.
Is it possible to allow these features on Intel cards? The opengl info log of VO says that it's disabling these, but it doesn't seem to see that they are available.
The log is here: http://pastebin.com/qywVKeDd

We actually forcefully disable texture compression for intel chips because of some extremely buggy driver versions in different linux distros.
Hi,
Another Intel/Linux user here. I noticed the same thing, shaders and texture compression being disabled. Would it be possible to add an option for advanced users (command line switch, configuration file) to override this?
I would be quite interested in trying out how well this works now, and if not, file appropriate bugs with the Intel devs. They are usually quite keen on fixing these things nowadays.
If it already works okay, maybe it would be possible to only enable it for certain combinations of driver and hardware? (E.g. shader functions and performance on my X4500HD improved quite a bit with latest Mesa, 7.8.)
Thanks in advance,
