Following John Carmack's recent .plan update concerning NV30, R300 and their Doom III rendering paths, as ever, this left a few more questions than answers. Reverend from Beyond 3D quizzes John for a few of those answers and manages to get some replies in this short interview. Q: What about the difference between NV30+NV30-path and R300+R200-path in terms of performance and quality? A: Very close. The quality differences on the ARB2 path are really not all that significant, most people won't be able to tell the difference without having it pointed out to them. Interview @ Beyond3D
