You should get your facts right before you tell something nonsense. The TNT already could do multitexturing (that's why it's called TNT). To be more educated the next time you can have a look at: http://www.rojakpot.com/showarticle.aspx?artno=88&pgno=1 BTW: multitexturing isn't that important any more. It was really important to do your own lighting (like Quake did). But any fancy effects are now done with shaders (but then you need at least a GeForce3; total freedom comes only with the current cards - but then you can do real "strange" stuff, just have a look at http://www.gpgpu.org/) The TNT2 was just an evolution from the TNT. The revolution was the GeForce. The next revolution on that line was the introduction of the fully programmable shaders. > I do agree that the TNT2 is very old and not up to it but mainly because it > just doesn't have the power to push and/or fill enough triangles/second. > 15 million transistors clocked at just over 100 MHz can only do so much. Yes, fillrate is also a problem. But I *guess* that the bottleneck with a current FGFS on a TNT2 would be the transformation stage.
