I bought and played DA2 the day it was released, enjoyed it for what it was, but noticed some serious issues with DX11 rendering. I put it down to my aging computer, and the fact that it was a brand new game, and stuck to DX9.

Last month I bought a new computer: i72600k, 16GB RAM, 2 GTX560 Ti's with 2GB VRAM running in SLI, and a 240GB SSD. DA2 was one of the games I really wanted to play through again, to experience the story from a female lead's point of view, playing a new class, and experiencing the game in all it's DX11 glory. Surely it had been sorted out by now, right?

At first I experienced odd flickering shadow bugs and frequent crashes. After updating my drivers to 280.26 the shadows are fine (great even!) but the frame rate was abysmal and I still experienced the odd crash. I disabled SSAO, and the game now runs without crashing, but between 20-30 fps in outdoor environments and in Kirkwall. Indoors it varies based on viewing direction, between 20-60fps. That directional frame-rate even occurs in cutscenes, with one scene in Gamlen's house jumping from 60 fps when facing him, and dropping to around 8fps (!!!) when focused on Hawke and her mother. I also notice some insane glitches during cutscenes in his house, with checkered multicoloured squares flashing up on the screen every few seconds.

What exactly is the issue here? Surely I don't need a more powerful computer? Is DX11 in DA2 just completely flawed? If anyone knows a workaround then I'd love to hear it. I'd like to try disabling tesselation and seeing if that improves matters, but the only way I can see to do that is to turn off ALL the DX11 features together.

Any advice?

Thanks for reading.

I am running a single AMD6950 and only 2 AA and get 30-40fps with dips into 20s. If you haven't tried scaling back the two sliders a couple of notches do so. As far as the other issues, haven't seen them, so either it is mods or nvidea drivers conflicting.

[Darkstorne]

I've now updated to the 285 beta drivers, and performance has significantly improved. Framerate is now constantly 40+ during gameplay. The dialogue cutscenes, however, are still bad. Framerate can dip down into the 20's, and the screen keeps flickering to black behind the characters. Very odd.

At least it's playable now. I'll just have to squint during the longer dialogue sequences to save my eyes >.<

I've only just started installing a few mods, and they're all hair and eye cosmetic changes (required for slight face changes to Anders and Fenris). All issues reported above were on a vanilla install.

I suppose that you have patched the game to 1.03 even though you haven't wrote it but if you haven't I strongly recommend you to do so. Otherwise, I'm sorry to say that I have no idea unless DA:II have a problem with slit that I haven't heard of.

I run the game pretty smoothly with a Sapphire Radeon HD 6850 and AMD Athlon X3 450 so according to me it should work perfectly for you and I hope it will soon

Do you have any graphic settings "forced on" on the drivers that aren't supported by DA2? That would cause slow downs for sure.

(Really the problem could be a lot of things. But I can confirm for you the Nvidia drivers have been fixed.)

[Darkstorne]

The game is patched to version 1.03, confirmed through reading the documentation. It's a Steam game anyway, so updates automagically. As far as whether anything is forced on, I had been forcing triple buffering on through the Nvidia Control Panel. After switching it back to the default setting of 'off', there's no change. The black flickering persists.

I'm still noticing certain areas cause huge frame rate dips too. I've just been in a cave that reduced my usual interior framerate of 60 down to single figures when looking in a specific direction, even when at the edge of the map - leaving nothing else to be rendered other than a cave wall, with nothing beyond said wall. Really stange behaviour

It's annoying, but not game-breaking, so I'm assuming there won't be any future patches for this game. I'm still glad Bioware pushed for DX11 tbh. Early adopting of technology will always have its issues, but it helps to push the technology too. Here's hoping they get to put this experience to good use with DA3, and give themselves more time to polish the finished product.

Cheers for the help everyone.

Try disabling AA (or set it to x2), also make sure you have installed latest drivers for gpu, but also for motherboard, sound card, dx11 latest drivers (June 2010!). And latest updates for windows as well. If this still not help wait for next DA2 patch / nVidia drivers update.

Steam may be the issue. Not certain though. I have my game on disc, but also set to run through steam. When playing normal I have no problems with lags or any other issues, but when I run it through steam the lags pop up. At least that's my experience with it.

I remembered reading this particular paragraph from a video card review on hardocp and thought it might help ya dark.

Dragon Age 2 is still a burden for modern GPUs, when you set the game to "Very High" it opens up several options that are taxing on video cards. The three settings that affect performance the most are SSAO, Diffusion Depth of field and High Quality Blur. NVIDIA has done a lot of performance work lately, and have gotten SSAO performance up, but Diffusion Depth of Field and High Quality blur still slow the GTX 580 down quite a bit. We found that even with No AA we could not have both of these options enabled. We found if we disabled them, we could then enable 2X AA on the ASUS ROG MATRIX GTX580 Platinum and reference GTX 580. This was the best combination of settings, and let us smooth out some of the jaggies.

Maybe turning one of the following options they mentioned off, will help your frame rates, because even a single super 580 can't handle da2 with everything maxed out.
