Hopin' to get a Dev response to this one. I know the full game has DX11 features and that they weren't implemented in the demo. What I'm wondering is how graphically-intensive the max settings are. I expect my GTX 580 to be able to handle anything you guys throw at it but I'm helping my little bro shop for a DX11 card and I didn't see a DX11 card in the recommended requirements so I was hoping someone might be able to give me some feedback on what DX11 performance is like in the final build and what kind of card he'll need to get achieve playable framerates (30-40 fps) on 'Very High' DX11 settings at 1680x1050. I understand it might not be possible to get a specific answer but I've got enough experience building gaming systems that even some general performance info should help me out.

My gtx570 choked on HQ max settings on dx11, dropping to medium pushed fps from single digits to 60-70@1920x200. Of course dx11 wasn't working right in demo so the card wasn't at fault.

Yeah, noticed the same thing on my GTX 580.

According to this review of AMD Radeon HD 6990 Antilies
DA2 DX11 supports:

"New in Dragon Age II is support for DX11 and several DX11 specific image quality features. You will find Tessellation along with Geometry Displacement Effects used to transform the landscape in Dragon Age II. Some other important DX11 features used are Advanced Dynamic Lights, Contact Hardening Soft Shadows and Diffusion Depth of Field. Screen Space Ambient Occlusion (SSAO) is also supported and works in both the DX9 and DX11 modes."

I have a gtx 460, will be enough to go the "very high" setting? in the demo it went very well with the high setting (1680 x 1050 resolution).

I was able to run High settings on a 570 pretty good in most places. I went into the config file and turned on every option. It dipped down into the teens and 20's sometimes, but was still playable.

I have the same problem. GTX 460 with old Core 2 Duo 2.6GHz CPU. Demo performed very bad in DX11, but they say there are performance issues, so I wonder how the full game will perform.

[AlphaMaeko]

I have the recommended HD 5850, which makes me curious just how well my setup will manage the DX11 stuff once the full game is out.

DX11 isn't even supported in the demo, so that's why people are seeing crappy performance when choosing it (why the option's even enabled is beyond me...)

I have an unlcoked and overclocked 6950, and I get a minimum FPS of around the mid 40s at 1080p/DX11/High/SSAO on/Forced 4xEQ MSAA, but ONLY if Anisotropic filtering is at 2x. I can get a 60FPS minimum with it off. That is, except in the scene where Captain Janeway sets fire to all the Darkspawn, where all the fire knocks the framerate into the 20s. Something is seriously up with AF performance in DX11 mode, though it's far from the only issue. I'm glad to see that even the GTX 580 is brought to its knees though, in a way at least, as it's definitely a problem with the game that hopefully will be remedied by launch.

As I noted in my previous post, DX11 is not supported in the demo, so any conclusions you draw about DX11 from the demo's performance are going to be erroneous.

For what it's worth I’m using a 6970, and had all the options i could enable to max on, despite what has been said about unsupported modes and found no issues with frame-rates or any graphic related issues, right up until the final fight with Hayder where it became jumpy and glitches. Maybe I was just lucky?

[Syrellaris]

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

The demo is about 1-3 months old. The full game shouldn't have any problems...

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

I know, it's strange, but part of me thinks that they DO use DX10 (though if they used 10.1 your 8800GTX would be left in the dust since only Radeon card ever supported 10.1 over 10.0). I just can't think of a logical reason why they would jump straight from DX9 to DX11, plus I've heard that nVidia 7-series owners are experiencing a good deal of graphical issues which may just be related to the demo but may also have something to do with the fact that they don't support DX10 features.

I have a GTX295, which I know isn't a directx11 card (Directx10, I think). However from doing a little bit of research, it seems the 295 does include a fair number of the Directx11 features (tessellation being the main exception). I have Dx11 installed on my machine. With regards to the full game, will I have to select Directx9 because I don't have a dx11 card, or will Dx10 be available on the drop-down menu, or will I able to select Directx11 and take advantage of some of the features?

Thanks in advance, and apologies if my question either seems completely ridiculous, or has already been answered. xx

Okay, so I've now posted in 3 different threads with questions about DirectX, 2 of which I started myself, and 1 of which got an answer from a Bioware employee (though not a Dev that worked with the graphics):

- The "Very High" setting, which is unavailable in the demo, is the setting that will enable tesselation and a bunch of other DX11 features and will only be unlocked if you have a DX11 card.

- The "High" settings introduces some DX11 features...likely the same ones you referred to, and also uses DX10 features.

- It sounds like choosing a DX9 renderer is like choosing DX9 + some DX10 features, and will disable the DX11 "Very High" setting.

My other thread is here, and the thread with the Bioware response is here (but don't expect much from the Bioware response, like I said, he's not a tech person).

Many thanks bikeracer. Apologies for making you post in a third thread.

Haha, no worries, it is my thread after all. Besides, I'll probably keep looking for more infromation on this DirectX stuff until either the game comes out or one of us hears definitively from an engineer what settings use which DirectX features.

2 GTX 560 ti in SLI are much, much better than a 580 with less price. Actually for that price tag is probably the best config you can have.

You're right about them being better performance for about the same price as the 580 but there are other considerations, i.e. they require more power than a single 580, produce more combined heat than a 580, SLI (while still much more reliable than CrossFire) still occasionally has issues with new releases, and the 560 limits you to only dual-card SLI, so 2 560's can't be upgraded, whereas I could still add another 580 to my system when I need it (hopefully not for a while). Anyways, essentially, I agree with you here, I just wanted to point out that there are circumstances where a 580 might be preferable.

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.
