Pardon my ignorance.  I've been playing on High Settings with an average framerate of 58.  In this article they have AF set to 16x and vertical sync off.  I have my AF at 8x with Vsync on.  What exactly do these two features do?  Again pardon my ignorance on this subject.

OK, now that I've actually googled these two settings, I have enlightened myself.

So what do you experts recommend. V-sync on or off? Will it help with my jittery framerate?
My framerate ranges from 40-61 depending on the action. I'd like for it to be more consistent. ME2 gave me no problems.

V-Sync is when it capps your rendering rate at your monitor's refresh rate. I usually leave it on because without cap my video card could render some of the old games at 500 fps and that will fry it out. My LCD refresh rate is 120, so even with V-Sync it will still only cap at 120 - e.g. a non-issue for most games.

40-61 FPS is normal. Shouldn't worry about it. A lot of ME2 areas are self-contained, so it is easier to render. Wide open spaces (such as Sundermount and Wounded Coast) is where my fps takes a nosedive, but that is to be expected.

v-sync is only useful if you have a lot of screen tearing, like when the top of your screen renders a from ahead of the bottom, it weird looking and rather distracting. but if your not having excessive screen tearing but still enable v-sync it can cost you performance.

I'll leave it alone then. Wasn't sure if v-sync off would bring my framerate average a bit closer. ME2 works flawlessly on full settings, barely dipping below 60. I guess I was spoiled.

Then again my DA:O had this issue with degrading performance the longer I played. A patch eventually corrected it. I can say DA2 on High works and looks a lot better than DA:O on very high.

I always turn Vsync on pretty much for the fps cap - unless the game offers an alternative method to cap fps and there's no screen-tearing, in which case I use the framerate cap option and leave vsync off...

The reason I always want to have an fps cap in my games is to stop the gfx card rendering tons of frames in completely unnecessary situations. For example my fps record on this new card is 2200+ frames - that was while idling in a game's menu, which started slowly pushing the gfx card upto 92 degrees, which was the point I decided to quit and force Vsync on the gme through the Nvidia panel (the game didnt even have the decency to include an ingame vsync setting).

As for AA and AF.. I usually set AF to 4x or 8x (depends a bit on how good the game textures look) and AA I may set to anywhere between 0x and 8x depending on how badly the game needs it. Some games just look much worse without AA than others do.

For example I tried the Rift beta and that was a good example of a game which desperately needs high levels of AA to smooth out the edges (the jaggies on those character and object models made my eyes bleed!). And yet other games I've played looked fine with 0xAA (though usually I still set it to 2xAA for good measure - you know, just to nip any aspiring jaggies in the butt).

At the very least this article shows in great detail how DA2 is horrendously inefficient, especially on the "very high" settings.

Great read, thanks for the link dude. BioWare, take notice and get your act together for ME3.

[TheAxeMurderer7]

I hope ME3 works as flawlessly as ME2 did.

As for the article. It is extremely hard to notice the differences between High and Very High in the screenshots. Makes me feel better that my 5850 can only handle High setting.

A 5850 should be able to trounce this game. It runs Mass Effect 2 at a flawless framerate. There's simply no excuse for this kind of poor optimization.
Dragon Age 2 was a rushed job, simple as that. The visuals do not justify the technological demands of the game.

I'm with you on that.  I still hope they release a patch that optimizes this game for DX11.

Correction on my settings.  I actually had it at 2xAF.  I moved it up to 16x and lost 6-8 fps.  I didn't even notice a visual difference.  As for V-sync, I see what you guys mean.  I only got a few extra fps, but now with screen tearing.  And the fps was in the 400-500 range in menus.   V-sync on is a good thing.

Until their is an optimization patch, my settings will be:
High
Hi-Res textures On
1080p
V-sync On
4xAA
2xAF
Ambient Oclusion On (aka fancy shadows)

If you have a 5850, the game will play great at these settings.

The most noticeable effect of AF is on the floor of games. If you look at the floor, close up will be detailed and far away will be blurry. AF seems to determine how far away the game switches from detailed to blurry. Personally I find 8x does the trick on Nvidia cards and 16x on ATI.
