How much does the TNT2 cost? Most of the hackers are very excited with
the G200 and esp. the G400 incld John Carmack! From what i have found
out, there is no competition to the G200 *in it's price* class.
Can i have links to the benchmarks and reviews for the TNT2?

Right! So dosent that make GLX an *implementation* of the OpenGL specs?

Quake uses the Mesa libs as it was the only open source implementation
of the OpenGL specs. Now that GL itself is Open(GL), perhaps John
Carmack and his team will use the official API itself, ie GLX.
I would definetly prefer to play quake from the console! Why carry the
excess baggage when u can leave X out. But then, GLX is not available
w/o X, so glquake from the console uses libmesa and not GLX!

Since, mesa libs were the only *open source* libs available for
programmers to work, all the programs have been written using the mesa
libs. I dont think anyone is using GLX as it will be appearing only in
X11R6.4.

Can't verify that! www.mesa3d.org seems to be down.

OK

Are u referring to Quake or some mesa3d demo progs? GLQuake will work
w/o GLX as i had pointed out earlier, it uses libmesagl.so!
Since u can render gl scenes w/o GLX, obviously u get h/w accelaration
w/o using GLX. Right?
Conclusion: Hardware based GL accelaration is possible w/o GLX as long
as u have mesalibs!!!
