I have thought for some time that Computer graphics seem to have really stalled.
I mean, ok, there have been incremental improvements here and there, but honestly...is there THAT big a difference between an FPS game from 10 years ago, and one from now? Well..not really. Not huge.
Compare that to the enormous advances in computer graphics in, say, the 5 years between the 8bit Commodore 64 and the 16bit Amigia and Atari Generation...
And compare that in turn to the huge leap from the 16bit computers to the PCs of the late 90s and the difference is huge.
I think we are due something properly revolutionary.
