Dear PC Gamers!
Far Cry 4 is a fantastic game, but on PC we doesn't have quality anti-aliasing solution. On the PlayStation 4 the game uses a wonderful new approach called HRAA or hybrid reconstruction anti-aliasing. This solution brings downsampling quality with very minimal performance hit (maximum -1 fps).
HRAA is possible in PC also, and I will prove it now:
HRAA is an analytical anti-aliasing based on four different types of solution (in two stages).
Stage one is the solution for temporal stability with TFQ or temporal flipquad, and TAA or temporal anti-aliasing. It will eliminate all shimmering issues without bluring the textures. This technique is possible on every hardware that supports DirectX 11.1 optional SAD4 instruction. Basically all Radeon hardwares based on the GCN architecture.
Stage two is the solution for high quality anti-aliasing even with transparency. The PS4 version uses AEAA for alpha test. This is possible on every hardware that allow the pixel shader to read geometry informations from the local data store cache. Basically all Radeon hardwares based on the GCN architecture. After AEAA there is a CRAA or coverage reconstruction stage with the real work. This is possible on every hardware that can access coverage samples. Basically all Radeon hardwares based on the GCN architecture, and all Geforce hardwares with Fermi and Kepler architecture.
As a "master-race" PC gamer I want to see this anti-aliasing solution on PC! We spend our money upgrading our hardwares to see innovation. And, it is so not cool that this wonderful anti-aliasing solution only accessible on PlayStation 4. This makes me think that the console is the new "master-race" for gamers.
