After hearing about Ray-Tracing being used during the Showroom in GT5, and during gameplay in Killzone2, i started to look around and read some articles on Ray-Tracing and how it affects games and various aspects of how the game looks and runs. Using Ray-Tracing and its aspects its able to greatly reduce the workload on the GPU/CPU allowing it too work on other aspects of the game. It also allows the games to match high AA, its able to re-create textures for importance and how each looks for where the user is in the level.
But the one thing i read in these articles is that real time Ray-tracing is too hard to do with modern computers, they mention that some aspects of it are used but they can cause bad effects in the game. The articles i read are from late 2006/2007.
But i would assume that Ray-Tracing is going on in computer games now, since the PS3 has used it. But i have yet to find an article that says aout it being used.
But is Ray-Tracing a step in the right direction or is it useless for modern gaming and too hard to use in real time without using too many resources to get it working.
