New selective supersampling demo

Humus' demo showed the benefits of what he did on the ground, in a single scene, with nothing else in consideration.

I don't think it's about the time Humus spent coming up with this.

Every developer have their own priorities when it comes to improving IQ in their games. Heck, even the IHVs may have a say in this and all this have nothing to do with AA!

AA have never been a priority for devs, other than slapping on AA support by querying resident card's DX CAPS.

Lastly, perhaps the word you chosed ("weary") can be substituted by "leery".

Like I said, Humus shows us what happens. Not what we should expect to see in games. Sad and frustrating as it is

 

He mentioned the overflowing of Xenos' eDRAM capacity.

 

You're right, the word I meant was "leery"; I appreciate the feedback. I still stand in agreement with Humus' post a few posts back.

 

The same overflow will happen with MSAA and SSAA.

 

Perhaps you meant "wary" rather than "weary."

 

Interesting. And I do have to mention that even if one could get something like the method I posted to work well, the one you posted has the distinct advantage of being applicable to any form of surface aliasing.

 

Well, you'r right about memory footprint - it's almost 1:1 match between sample-count identical modes (2x2-vs-4xMS, 4x4-vs-16xS) but the performance hit degree is "impressive" for SS modes.

 

It is a 1:1 match. MSAA is more compressible, but due to its nature, you still need to reserve the full buffer amount.

 

Of course you can do better in most cases if you store additional samples separately, but then it gets much more complicated. But it can be done and has been done.

 

Hence my initial question.

 

If you're CPU bound 2x samples aren't that many, to make a huge difference. Of course is adaptive/selective Supersampling in combination with MSAA and AF way more attractive.
