Try putting everything on high, including AA and AF, then dropping it down to DX9.

[ArmeniusLOD]

Medium quality is only using DX9 hardware level function calls, High uses DX10 (theoretically and hopefully), and Very High uses DX11 calls. DirectX 10 was notable for its lack of performance so I believe that is the issue (in theory ).

I had the same issue with very poor performance and I'm running a GTX 580 and i7 950. I found a Bioware post though saying that the demo has performance issues with DX11 but that these issues have been fixed in the final game. See here:

DX11 + Medium Settings seem to be stable for me, though I'm not sure there's much difference between that and DX9 + Medium settings.

My frame rates are much worse. Even on Medium, I'm dropping below 20 fps in battles, and the city location in the demo is painful to walk through. My system beats the recommended specs. I don't game on the PC very often. Maybe my expectations are too high, given my hardware? My graphics card is a Radeon HD 5970.

I play at 1920x1200 with DX11, high graphic and graphic is not so good and also slow.

I have a gtx295 + core2duo e8600 @3.8 ghz.

I know that my vga is not dx11, but I don't like that there is only dx9 and dx11 and dx9 users can only select medium graphic.

What's the rest of your hardware? CPU, Ram...
I have a HD4670 and i keep above 20fps when on dx11 and hight details. Medium keeps steady between 50 and 60.

I played demo via Bootcamp (Win7, 64-bit) on my MacBook Pro 5,3. 2,66GHz Dual Core, 4 GB RAM, 256MB GeForce 9600M GT. I can only get steady 30FPS at medium details and 720p resolution.

Some tips to running in DX11 I found very interesting for nVidia users with SLI setups and Stereoscopic 3D hardware (works good both in Plain 3D and Stereoscopic 3D):

As you know Dragon Age 2 Demo is out today and it comes with some bugs( non optimizations for 3D). So I am going to tell you how to play it at best settings available:

1. First of all some claim that it doesn't have DX 11 support. FALSE!!!! IT HAS...so navigate to Video and choose DX 11. Then select HIGH for Video profile ( HIGHEST IS DISABLED in demo). RESTART THE GAME!!! Now if you start the game you will have like 15 fps (on QUAD SLI 2xgtx 295(and I know GTX295 is a DX 10 card but works in DX 11 nevertheless)) in stereo 3D + ghosting and various shiets...err artefacts. (Try it to see the diff).
2. Now go to Nvidia Control Panel and disable 3D support. From the menu bar choose 3D Settings > Show Multi-GPU Visual Indicators and start the game. Well what do you know...NO SLI BARS...because the default nvidia PROFILE DOESN'T HAVE SLI ENABLED >:
3. Nicely navigate to your install folder and rename the DragoAge2Demo.exe(in bin_ship folder) to Metro2033.exe ( we need a game with DX11 and 3D support). Launch the game...WOW we will have like 60 FPS in plain 3d from 30FPS (non SLI Plain 3d).
4. Activate the 3D Vision support from nvidia panel..and play the game.

PS: If you have any other profile of a game that supports DX 11 and offers better graphical results PLEASE let us know. Hope this helps someone;))
Also DX 11 is not officially supported in the demo ( the bad performance etc...should be fixed in the final release... ) 

Best Regards,
Me

The DirectX 11 renderer is a software implementation, and High quality uses DirectX 10 hardware calls, which is why you can run it with your GTX 295. Very High uses DX 11 hardware calls and will be available in the retail version, which you will not be able to use with your GPU.

Not really on topic, but kinda I guess:



Could someone make a screenie with DX 11 of Cassandra (from the not pre-rendered scenes) please? I'm playing with DX 9 and it's really bothering me that her hair seems to be different (pre rendered - jet black, rendered - ashen). I'm interested if it's because of the inferior shader or is it just a bug or demo thing or something?

So it may be:) I don't want to use DX 11 on a DX 10 card..only DX 10:)) I wrote the above post in case someone is interested in "quick fix" if they have a SLI setup (don't know for Crossfire).

First, I had a typo in my original post.  My graphics card is a Radeon HD 5670.

So, I just tried DX9 for the sake of it, wondering, is DX9 locked at 30fps?

It's constantly at 30 now, jumping 1 or 2 fps higher every now and then, as i mentioned before with dx11 and medium i run at a stable 50.60fps.

I'm just curious, choosing DX9 for me lowers the max settings I can pick. Example: I can only pick Medium in Graphics Detail and Anisotropic Filtering is disabled. As for the other settings, I set Anti-Aliasing at 8x and enabled Ambient Occlusion, resolution at 1920x1080 and just by eyeballing Fraps during the rendered opening scenes and the first battle I look to be averaging about 170 fps, though it can vary between about 110 and 230 fps depending on the scene, and I'm using a GTX 580 and i7 950. Enabling DX11 and setting details to high as well as setting filtering to 16x drops me down to 28 fps and introduces the graphics artifacts, though thankfully Bioware assures us that these issues are only relegated to the demo...

[The-Sapient]

Tried updating my video drivers, to no avail. I wish I knew if this was as good as my system is, or if I could do something to make it better without actually buying anything.

[Siegfried.m]

But in the game can I use at least high details if I have only dx10? It's really a bad bad thing if I can use only medium settings if I have dx10.

Which means your graphics card is one generation newer than mine, basically, it should be better, and I have a hard time seeing how a quad core at 2ghz wouldn't be strong enough, I don't use AMD though, but as far as i see you should be able to run medium on a high and steady fps...

Well, I played trough the demo using the DX11 renderer and could use high details, and my graphics card sure isnt a DX11 card so

And yet I can't get my frame rate consistantly above 25 FPS no matter what settings I choose.  I haven't used a PC for graphicly intensive gaming in a long time, so maybe there is some setting somewhere that I don't know to check?  I goofed around with ATI's control center settings quite a bit with no real changes to performance.  Could me CPU really be choking the game this much?

[RaenImrahl]

Your AMD processor is strong but not top-of-the-line. DA2 uses the same engine as Origins, albeit supposedly better optimized. Origins is a CPU pig... ultimately, it's not about how many cores you have (beyond two) but also how fast they run. So a 2.0GHz clock speed means you'll have to govern your expectations a little.



That said, you could try the demo at the lowest res/no AA/low graphics/no vert sync and see how much that improves it. If it's not by much, then there's something else that needs to be optimized in your system. If playing at rock bottom does improve things dramatically, then you can incrementally increase settings until you come up with a good mix of visuals and performance.



Two other thoughts... first, try it without any enhancements from the Catalyst software. Second, you may need to do the same procedure when the full game comes out... I don't think the demo is a good representation of the engine tweaking Bioware/EA has alluded to thus far (other than combat animations,which are shockingly fast).
