Anti Aliasing

by Niklas Hansson

Since some people had a problem with the aliasing in Project Temporality we decided to ga ahead and do some investigations. Since we are using a deferred renderign engine using MSAA wasen’t really feasible on the xbox which left us with the options of doing some cheap depth blurring or to look at the possibility of MLAA or FXXA after a short evaluation FXAA (developed by Timothy Lottes for Nvidia ) seemed like the best performance vs Quality compromise. So we started playing around with it and the different settings. FXAA on a higher setting that can easily be used for example on a PC is really awesome. For the XBOX you have to make some compromises. But in the end we feel that it is still alot better than no AA and at a totally acceptable performance loss.

We have just started to play around with it and there is a lot of more work than can be done but the results are really really nice.
