I told you already, because FCAT basically just measures frame metering by penalizing "race to display" style AFR implementations like what AMD is using currently (but as far as I know, will ship a...

It's similar to dual-graphics for SSAA - i.e. at least it works and provides some benefit all of the time, but it's a very brute force way to do it. i.e. you don't need 2x the power to render a...

Yep, and I even think you're giving it too much credit in its current incarnation. It's a review gimmick to capitalize on the halo effect, not a serious solution.

Because FCAT is basically just measuring frame metering, which is something that NVIDIA is doing now and AMD is not (yet). How much you care about it - or multi-GPU/alternate frame rendering - is...

Steam handles integrated/dGPU stuff properly (they obviously are aware of this); otherwise you'd see a hell of a lot more integrated on there :)

Nice web site and numbers! Now we just need to get prunedtree's BC7 compressor released :)

Publicly that's probably one of the better ones, but as you note, very brute force and slow. BC7 has a number of different compression modes that can be picked per-tile, so depending on how the...

Which BC7 compressor were you using? I ask because the ones available publicly right now are mostly pretty terrible. I would expect BC7 to do at least as well as ASTC at similar bit-rates. Of course...

It's better at low bit rates, but BC7 is similar at 8bpp (RGB/RGBA) - i.e. very high quality. It'll be good to have both available in the long run of course.

Maybe for a discrete GPU, but I don't see a problem on integrated where it's using the same memory hierarchy anyways... both AMD and Intel are going this direction.

Right, introducing a new (often complementary) market is not the same as "losing" market share in the established one.

Meh, direct state access on GL makes a really old API somewhat less ancient and crazy. The pointer-based state on DX is efficient enough.

The big overhead is just with all the resource stuff that...

Depends where the bottlenecks are. If you're entirely pixel-limited (even at 1080p60) then sure, it's pretty linear. However increasing resolution doesn't increase vertex or CPU work (typically,...
