Quote:Oh yes, that's right - shaders!
On a 980 574ms for the merge stage alone depending on the scene. Tri SLI with perfect scaling would get you just under *six* frames per second. Keep acting like you got a clue kid.
Quote:What's the difference, Ben? I thought both variants of SGSSAA were sparse grid.
They are both cheap versions of stochastic, one of the issues I have with modern AA terminology is we were using all of these techniques dating back to the early 90s in some instances and we had different names for them then(and some of the names we had they just swapped, heh). Consistency on a frame to frame basis is the big differentiation. Using a consistent sampling pattern versus jittered offsets or straight randomness.
Quote:Looks great, except for the artifacts as explained in Figure 10. I wish the article would have made it more clear how often those artifacts would appear in games.
Simply a factor of granularity used in stage one and not truncating too much in the merge stage. In other words, you have a dial you can use- reducing artifacts close to zero would probably be several orders of magnitude more intensive then having a small margin of error- edge cases, as always, will be your undoing here.
Quote:Blurred texture, incorrectly merged, incorrectly discarded, and z-prepass artifacts probably won't be a common enough thing but I expect Nvidia to spend a lot of time making sure it's not an issue in the games we play (the z-prepass artifacts the most of all, especially).
This isn't from nVidia, they are hosting a doc that was written by what appears to be some University students. Nothing wrong with that of course, but it isn't something nV's developers are likely to be actively working on. RAM is cheap, TFLOPS of spare processing power, not so much.
Quote:Nevertheless, I think both NV and AMD will be seriously focusing on bigger resolutions this generation. 5K is insanely demanding though (unlike how 5K sounds compared to 4K - a kinda lame naming scheme) but AMD and NV will have to try their best to stay ahead in case 5K monitors take the spotlight with review sites.
5K will likely pick up about as much traction as 2K- in other words, very little. The reason 4K is such an easy swap is it is a clean pixel perfect downsizing for 1080p content. 5K won't fail, but 4K will be *the* standard until 8K picks up.
