Wickedgl and s3tc (unreal & UT)

[ucanmanda]

Is there a way to use wickedgl with s3tc textures in Unreal or Unreal Tournament? I can use those textures using Mesa 6.2.0.2s combined with latest ogl renderers but wickedgl drivers are faster. If I only could get wickedgl speed with mesa image quality...

Is it possible?
