Well, before posting this i've been investigating a little bit and i can safely say that the RED Engine is a DX9 based engine. Which is quite awesome in an on itself by the way it looks.

Having said that: Can PC gamers expect a DX10/11 patch coming someday before Judgement Day? :P
I know that a lot of you will say that fixing what's broken comes first and i totally agree, but think for a second. Performance on fairly new hardware is one of the issues PC people are experiencing, so it might be a not-so-bad idea to develop a DX11 patch for the game in order to smooth out some of those issues.
Just sayin'

DX11 doesn't seem to solve issues so much as create them, and DX10 doesn't really do much except break hardware sound.

They have to make the game work properly for (almost) everybody in DX9 first, then find something that DX11 can do better and that can be worked into the engine.

If the engine doesn't use any DX 11 features, what would be the point in a DX 11 patch?

Make gamers' epeen grow because they can say it is a DX 11 game?

e-peen is sexy fun

Using DX11 properly is not so much a matter of "patching" anything than it is a matter of re-writing the engine. You'd have to put a vast amount of effort in it.
I can't imagine they're going to do that. Lately, Creative Assembly co-developed Shogun 2: Total War DX11 along with the DX9-version and released a 'patch' which implemented it - therefore probably your idea of simply patching it in. If you compare it to DX9 I'd say it's hardly worth the effort to start over AFTER finishing the DX9-engine and -game. I guess it would take months upon months - for (to be realistic here, although I like the new DX11 features) pretty minor improvements.

Also, a DX10-patch would be totally pointless, as DX10 does have hardly any new features and was only supposed to make certain things easier for the devs - which didn't catch on either due to the need of using DX9 anyways for XBox 360.

i dont see why not dx9. crysis 2 is a dx9 game and it looks pretty good. and on any DX11 capabale computer DX9 is always smoother than DX11

why is it surprising that it's dx9? dx11 doesn't offer that much of a visual benefit. and performance wise the difference are even less.

don't buy into the microsoft hype. it's just videocard selling gimmick, nothing else.

thanks.

Not true, either. If used properly (meaning: not overdoing the tesselation and soft shadows, optimizing other stuff with DX11-capabilities superior to DX9), DX11 can in fact bring along a (slight) performance boost.

"It was possible to do DirectX 11, it wasn't that we're against it, but when we laid down the cards and schedules, we looked and said, ‘okay, these are crucial features, we'd like to have them'... these didn't require DirectX 11. It was like, ‘If we can focus on other things and the lack of DirectX 11 won't make this game crap, let's think about it later on.' It's still possible in the future, but not right now anyway."

Well in that case the GPU are either super good or super bad. You hardly feel any increase in performance for most of graphic cards.

That i didn't see, well guess it's not bad they're still considering it. Once again, if they hardly use any of the features that DX11 offers, then there's no point in implementing it.

Thanks for that quote :)

So, is the patch coming out tonight or not?

I'll go along with that. It's very likely that the boost can't be felt, as it's far too small. And mostly DX9 will be faster, because devs want to use the new capabilities of DX11.

All I'm saying is that the statement "DX9 is always faster/smoother" is wrong, because if you're trying to do the exact same thing, you have certain tools and possibilities in DX11 that let you do it a little bit more efficiently.

It looks pretty enough under dx9 already... it ain't really necessary.

Maybe they'll use dx11 for the witcher 3.

yeah i k what u mean man
