So why the decision to allow Dx9 and 11, why not 10.1 and 11? It does not make sense.

I guess its time to update my old faithfull 8800 GTX

Because a lot of people are still using XP and that XP users cannot install DX10 or DX11. On the other hand you can pass DX10 commands to DX10 hardware via DX11.

So the decision makes sense. DX11 renderer for DX11 and DX10 cards... DX9 renderer for XP users.

Huh...interesting...but it makes sense...and would explain why so many GTX 200 and HD4000 owners are able to run DA2 with DX11 selected...

My 5850 plays the demo on high with 2x AA/AF and DX11 renderer pretty well. 45-55 fps during fights and moving around. 60 FPS constant during cutscenes.

Hmmm, Hard OCP did a preview of the AMD 6990, and they thought the AF performance issue was with the drivers, but it sounds like it's with the game itself if Nvidia cards are experiencing it.

Well, I dunno if you've heard otherwise in other threads but changing the AF options had little to no effect on my 580 at 1920x1080 resolution.

As a matter of fact I have a HD4850 that runs perfectly in High Quality settings in DX10 mode via the DX11 renderer (the DX11 functions having been stripped from the demo anyway as there was performances issues that Bioware said will be fixed in the final game)

The only problem in the process is that:

- XP users or owners of an old DX9 card will be limited to Low and Medium quality.
- Vista and 7 users with a DX10 card will be limited to Low, Medium and High quality.
- Only Vista or 7 users who own a DX11 card will be able to access all the settings (low / medium / high / very high).

It's kind of tradeoff that Bioware made to try and allow most PC users to play the game (no matter the OS or card DX version, as long as the hardware is fairly recent)

Yes but at the same time did you look at the test setup? It was mainly to test EyeFinity at an insane horizontal resolution. If an AMD HD6990 can run the game in a playable state at (let me check...) 5760x1200 in high quality with 4AA 2AF and SSAO you can expect it to perform much better at a more "normal" resolution, something like 1920x1200 or 1920x1080...

Edit: And still their test was on the DA2 demo not the final game. DX11 functions are not even available in the demo so I would take the OCP test with caution (even themselves say that).

I tried enabling DX 11 in the demo (have a 460 GTX). The result was pretty hilarious. Single-digit FPS and half the textures seemed to be missing.

Luckily I knew it wasn't actually supposed to work in the demo, or I would have been worried

[Lord_Saulot]

Am I the only one who finds using the DirectX9 renderer crash-prone and borderline unplayable, but can set the DirectX11 renderer and play bug-free?

[DalishRanger]

Nope, I didn't find any particular bug issues when running with DX11, either. Not in English, anyway. I played the German demo as well and the option was locked out, as were a lot of the higher graphical settings.

DX 9 - 40-50 fps, no crashes or hiccups.
DX 11 - 40-50 fps dropping to 2-3 fps sometimes, ctd's... I mean that sucks >.< My gfx card isn't all that new but nvidia gtx 285 really can run SC II in multi on ultra and there's no problem, civ V on max no problem too. I think there are some issues with dx 10 support on this game or nvidia side. I've got the latest drivers and still I get crappy performance in DX 10/11 mode.

Have you tried it with the 266.58 drivers? I saw noticable improvement with most games using the GTX 460 768mb Superclocked.  Though I admit I didn't try the demo in DX11 because they stated it wasn't supposed to work.

I think the problem might have something to do with a handful of DX11 features STILL being activated, as you're right that in thinking that your card shouldn't have THAT much of a performance handicap, and those of us with DX11 cards don't seem to experience quite the same performance hit... That being said, I'm pretty sure the DX11 performance is off for everyone so I wouldn't sweat it.

I have a Radeon HD 4890 which is a DirectX 10 card. I understand the issues with the demo with DirectX 11, but why won't it let me even select high settings. The demo says high can be enabled if you have a DirectX 10 hardware and use the DirectX 11 renderer (and I meet the Vista SP2 requirement, too). However, it won't let me select the DirectX 11 render, which then won't let me select "High" settings. I don't understand why I can't select it. I'm stuck playing on "Medium" and I think the graphics look horrible on that setting. This does not make me want to play the full game if I'm stuck with these settings when I get it. Does anyone have any ideas as to why I can't select it? Will I be able to select high when I get the full game? Thanks

Huh...no, far as I know everyone with a DX10 card has been able to select the DX11 renderer...in fact, you'll prolly get a few responses from people on this thread confirming this. You may want to try the thread about people's cards being detected incorrectly, as this might be what is causing your issue, or if that doesn't help you may want to create your own thread since in this thread, people will only see your post if they come here wondering about DX11 performance.

I had the same problme as you. I fixed this by downloading a patch that enabled Vista to support D11X on Vista's OS. If your OS doesn't support D11x (type "dxdiag in search to find out which version of DX your browser currently has), then you should download the link on this  page (the one marked "install"). 

Just make sure you download the right bit number associated with your processor.

I bought brand new Mobo, CPU and RAM right after experiencing problems with the DA 2 demo in DX 11 mode.

I had a vertical tear issue which happened only during the "in-game cutscenes" with my old rig equipped with a 6950 unlocked and over clocked on my old Rig.

But finally after installing the new Rig, the vertical tear issue disappeared all together. Performance during the whole demo was VERY GOOD even with AA x 8, except for the part just before the Dragon Flemeth first appears. (The very first part where you only play one character)

My computer shoots a warning saying that windows wants to change the color scheme to Basic because graphical performance is suffering greatly. (This happened to both rigs)

My problems was initially a CPU bottleneck but then migrated to a GPU performance issue.
My Video Card registered from an idle temp to a max of 76C the moment the game loaded up, it was very harrowing indeed (for the gfx card).

Other than the dragon scene, everything else was impressive and never dipped under 60fps.

Old rig:
CPU: Phenom (Gen1 Black Edition) 955 O.C. to 3.2 GHz
RAM: 4GB, 2 x 2GB Kingston CL9 DDR2 1066 O.C. to 1066
MOBO: ASUS MA478.
GFX: ASUS 6950 unlocked to 6970 O.C. Core to 900MHz, Memory to 1400MHz
Boot Disk: Intel X25M 80GB
Game Disk: Western Digital Black SATA2 1TB

Specs of new Rig:
CPU: Sandy Bridge 2500k O.C to 4.6 GHz.
RAM: 8GB, 4 x 2GB G.Skill CL7 DDR3 1600 O.C. to 1600
MOBO: ASUS R.O.G. Maximus IV
GFX: ASUS 6950 unlocked to 6970 O.C. Core to 900MHz, Memory to 1400MHz
Boot Disk: Intel X25M 80GB
Game Disk: Western Digital Black SATA2 1TB

They disabled bits of the chip for a reason. It probably is one of the 6970's that didn't make the cut, but it had enough working innards to be rebranded as another 6950 (AMD does the same thing with their CPU's. If three cores are working, but the forth one is defective, they rebrand it as a triple core). By "unlocking" the locked bits, you've probably introduced instability or something similar.

If there's a way to reset that video card to factory settings, or re-"lock" it, or whatnot, I would try that and see if windows is still giving you the "I'm running out of graphics memory" issue.

[Alauzhen]

I admit that could be the issue if mine was an isolated case. But I'm not the only one affected in this manner.

And I've not experienced any performance issues in other games such as Crysis, Fallout: New Vegas, Civilization 5, Magicka, Dungeons and many many other games. Of these games, Civilization 5 already supports DirectX 11 and it runs like a charm with no issues yet for more than 5 hours at a single sitting.

I'm quite sure it's just that the Demo ain't optimized for DirectX 11 yet. =)

I just did that last night but only had the single-digit fps when Very High was selected with max AA & AF.  Turning AA & AF down to x2 and the settings on High the FPS are okay.  Not as smooth as the DX9 though, but as we were told DX11 wasn't supposed to be supported anyway.

[KenRed]

Why is everyone even wasting their breath talking about DX11 in the demo when its not even supported? Give it a few days and then complain when it doesn't work in the full game! hahaha j/k

Well, I think, for the most part, everyone knows about the DX11 issues in the demo. The thing is, SOME people have it working at a playable level, so I think those that DON'T have playable framerates in DX11 are just trying to figure out HOW. Also, there's more than likely a few who are just trying to be reassured that it WILL work proplerly in the final release.

[P4NDA_Titan]

 My baseline HD 5830 can run DX11 at everything full with a tiny bit of lag during some cinematic sequences, and overclocked in Catalyst Control Center it can go full with basically zero lag. Not sure how this is going to work when "Very High" is implemented though
