Paul: T&L is overhyped and there are currently no games that uses it much. While only very few games use T&L (effectively) today, I most certainly do not think it is overhyped. The advantage of the X-Box was always that games would be written FOR it. That definitely includes using T&L fully. And when you add the (free!) clipping part to the picture, the reasons for supporting TCL completely are overwhelming. Also it does not reduce memory bandwidth in any signiciant manner, it is suppose to be a secondary cpu so that the main cpu doesn't have to do work. The CLIPPING portion of TCL can reduce memory bandwidth quite nicely. It's a completely different approach than tile-based rendering (which basically "just" improves cache hits), but it should be noted that the two methods would compliment each other well. Why does Nvidia have to use ultra fast 250 mhz DDR for their cpus if memory bandwidth isn't an issue? Because PC users run games in resolutions like 1024x768 and higher. Using a TV, this isn't going to be possible (NTSC is 340x420 @60Hz, PAL resolution is a bit higher, but the refresh rate is only 50Hz). for computers, free FSAA is a big thing You bet! We agree completely here ;) raditional methods would decrease performance by 2x or 4x depending on type of FSAA. Actually, tile-based renderers experience much lower penalties for AA (again the cache argument). This may be what GigaPixel is referring to when they claim "free FSAA"... -fyo
