Re: [Dri-devel] DRI vs. Xi Graphics performance

[Justin A. K. <jko...@ui...>]

Oops, brain fart.  I meant to say this:

I think the deal might be that their drivers are optimized for 
professional applications, like CAD, and whatever else the SPECViewPerf 
benchmark measures, not games. That would explain a lot of things: 
non-standard fullscreen interface, the cost, the fact that they sell it 
for Solaris, and last but certainly not least, the price.
