FXAA Question Cant figure it out
  1 / 2    
Hey folks! I understand how powerful FXAA is and it is performing better than 4MSAA but i have a question

When I turn on FXAA through the Nvidia Control Panel for a specific game, do i have to turn off other AA features?

Or should I Turn off AA within a game to allow FXAA to be forced via control panel?

Or should they work together?

For the love of GOD I cant figure it out.

They can work together, in DX9 and above games.
But they are 2 different things, so you can use one at once too.

Now I'm testing with DX8 and DX7 games.

Using the injectors for SMAA and FXAA, we could still use the MSAA as well. (SMAA being similar to FXAA, but with less blur)

For awhile I was running Skyrim with injected SMAA, 2x MSAA, and 2xTrSSAA, it was pretty excellent quality-wise.

With the new driver out, I've been playing with just the in-game FXAA, disabled MSAA and TrSSAA, adaptive v-sync, and max prerendered frames set to 1 (to reduce input lag).

Edit: TL;DR, the AA you use depends on your system. If you have ample GPU power, might consider combining several methods of AA. If you have lower end hardware, you may need to use the minimum, which would be a fast but powerful algorithm:

The minimum in my opinion, would be based on FXAA or SMAA based on it's superior quality-to-performance ratio over MSAA+TrSSAA.

To even approximate FXAA you would probably need 4xMSAA, plus TrMSAA, which is far more costly than post-process AA like FXAA or SMAA.

TL;DR: FXAA will provide high quality edge and transparency anti-aliasing that may be especially beneficial to the non-high-end hardware. Or to high end users who want extreme FPS.

i turned on fxaa and did not notice a difference in bf3, i turned on and off the in-game aa setting as well. What I "did" noticed was that with fxaa on , windows live mail gets some blurred text ...what am I doing wrong ? is FXAA supposed to achieve good eye candy and better frames opposed to using gpu crunching in-game aa settings?

FXAA's benefit is that it works with games that are incompatible with traditional full scene antialiasing methods. Yes it performs well, but quality is not the best.

FXAA actually is not better than 4x AA, it is just a good already effect to remove the Aliased object borders that is 60% faster to do than 4x AA but 4x AA still have a better effect but for real time gaming the fxaa is awesome because it removes the alising problem keeping a good performance.

You can yes use FXAA over other AA but that would just be waste of postprocessing, you will be wasting frames by doing so, so for the FXAA improve your frames remove the other AA effects.

if you have already maximum framerate possible for your refresh rate with AA and the game have it well implemented (or even via nvidia panel forced AA) keep the AA because it is better than FXAA.

Use it in any game you want, just have to deal with slight blurring of the entire screen. Even in newer games like Skyrim there are situations where MSAA fails, FXAA in essence can pick up the slack.

I have the problem that I can't turn FXAA on in the Skyrim tab via the Nvidia panel.

Is there something that I have done wrong?

No, as was explained in the article linked in this thread FXAA is made available as a selectable option in the driver menu unless the game already has support for FXAA. Skyrim already supports it as an in-game option. Go to the options menu of the skyrim loader then advanced and check the box that says FXAA.

Exactly.

But the driver-provided FXAA will probably grow in quality and performance in future releases: so why block it in profiles of the FXAA-shipped games?
The perfect solution will be a driver-override option for these games so driver FXAA can overtake game "native" FXAA.

it is not "Automatic" you need to Enable it via game Graphics panel settings, and by doing so you can remove Anti-Aliasing you will gain a lot of performance (if you aren't already running it at smooth)...
