Yes, I observed an ~8% improvement in
Hi,
i965 texture fast upload path did not work in 9.2.x due to this tiling
change, but was improved for 10.0 release series; however, you need to

hit it. With that, upload on 10.0.x should be almost as fast as on
9.1.x. Funny

Hello,
I have an application that on each frame fills a full-window pixel buffer
and then calls glTexSubImage2D() and maps the texture to a screen by

CPU @ 2.20GHz (brw->gen == 6), OpenGL 3.0, direct glDrawPixels() is much
