Oh, well.. Until AMD manages to get its quad-core act right, I'll have to stick to this out of loyalty anyway. I suspected I was being unnecessarily benchmarky. Oh, well..

As in "rendering an image in 1995". :) I read that Carmack interview last week and I have agree with him. Real-time ray tracing starts to be a realistic thing for the masses but rasterizing has a pretty good head start. Maybe some kind of hybrid will be the future. It could already be possible to do low-res radiance by ray tracing and the detailed rendering with rasterizing. Btw, thanks for the links. They should be rather interesting for folks who are interested of stuff like this. My guesstimate of how long it takes on my 3000+ is really a big guess — in any case, it didn’t take a LONG time.

I recall intel having made a realtime ray-tracer for Quake4: http://blogs.intel.com/research/2007/10/real_time_raytracing_the_end_o.php John Carmack: http://www.pcper.com/article.php?aid=532&type=overview Odd about the rgba rayracer, though; it takes 20 seconds on my 1.8 GHz (3400+ish) x2 laptop and 17 seconds on my 3600+ desktop. Anything I'm missing? That’s awesome. I recall intel having made a realtime ray-tracer for Quake4:
