Anti Aliasing and Edge Smoothing

[slizzedy 70]

I have a HD7870 and all settings in the catalyst control panel are set to application settings (dont know the english term sorry).

 

I see only very little difference between anti aliasing off and very high, but a notable drop in performance. Check the screenshots, edge smoothing is set to off.

If this is MSAA then very high should be like 8 sample, and 8x MSAA certainly does make a bigger difference in image quality than you can see on my screenshots.

 

Also using FXAA/SMAA and anti aliasing together seems to break both anti aliasing and edge smoothing, but still costs performance.

However when using only FXAA/SMAA I get some proper anti aliasing but not on all objects/not from all viewing angles (look at the scaffolding in the back), which I believe is in the nature of FXAA/SMAA. Also there's absolutely no drop in performance from edge smoothing.

This is kind of confusing, is it normal that AA+Edge Smoothing completely breaks both of them? Is it an AMD related issue?

FXAA

• Does not require large amounts of computing power, achieved by smoothing jagged edges according to how they appear on screen as pixels, rather than analyzing the 3D models itself as in conventional anti-aliasing.

 

MSAA

• The edges of polygons (the most obvious source of aliasing in 3D graphics) are antialiased.

MSAA starts first, FXAA works with the interpolated Frame after

Theory and praxis - two completely different things.

@OP: Does enabling ATOC cause the grass to look like many ##### for you?

Yes it does.
