Help For Antialiasing!

.

 

If you have the rig, supersampled FXAA is the way. TAA for me has a lot of weird leftovers during movements (wipers leaving a trail etc.), pretty weird behavior for supposedly the "best" AA method.

 

I have TAA, I’ve done FXAA with screen percentage enabled at 150%. I play 1440p rendering it at 4K, but I noticed some flickering lights as a result so went back to TAA.

 

TAA all the way, with full 4K. Takes care of just about everything, except some minute flickering here and there.

 

Supersampling > TAA > FXAA

 

This.

 

If you're using TAA, I would recommend using these Engine.ini tweaks to reduce flickering and ghosting.

Code:

r.TemporalAASharpness=2.0
r.TemporalAASamples=4
r.TemporalAACurrentFrameWeight=0.2

How do I use supersampling

 

I wouldn’t bother, it isn’t a patch on TAA, certainly at 4K.

‘Supersampling’ in this instance is changing the screen percentage in settings. By scaling the image at higher than 100% you are rendering the game at a higher resolution, which is then displayed at your monitors resolution. In theory it is a form of AA that works, but I’ve yet to see an example of it in action that looks better than proper AA.

If you turn AA off and render 4K at 200% (so effectively an 8K image on a 4K screen) it still looks awful. It still flickers and has poor image quality with jagged edges everywhere.

It might look ok if you upscale a 1080p image to 4K on a 1080p monitor but at higher resolutions TAA is the only way. It is way more FPS friendly too.

 

This is the reason why I use TAA (hint: it's in the name). Temporal artefacts like flickering can't be wholly mitigated by supersampling, at least at reasonable resolutions, so temporal antialiasing is the much better way. The flickering of moving objects is what is most noticeable in a simulator, especially since you are always looking ahead into the distance with scenery flying by, so it is only natural to use the antialiasing technique specifically designed to reduce those aliasing artefacts.

It makes a huge difference at 1080. And you can run both, it isn't either/or

 

You can do it more directly if you have an nVidia GPU; open the control panel and you can set oversampling options, up to 4.0x. And, again, you can use it in addition to TAA.
