[Dri-devel] Radeon 7500 (QW, AIW) slowness

[Pontus L. <po...@ly...>]

Hello,

I was quite surprised to see that my OpenGL application ran about 3x
slower with the latest DRI drivers (last week's CVS) and my brand new
Radeon 7500 AIW card. I think I tracked it down to
glDrawBuffer(GL_NONE) when drawing to Z buffer is enabled. I guess
this is a software fallback case; maybe the status page at
http://dri.sourceforge.net/doc/feature_table.html#R100 needs to be
updated? What is the priority of this functionality getting hardware
acceleration?

Regards,

Pontus
