I noticed upon playing with the much anticipated patch 1.07 that the whole world looked worse than it did with patch 1.06. I played aorund with many of the settings, and finally cme to discover the issue.

All diagonal edges are now jaggy. Only perfectly straight lines don't show any artifacts. I went into the Postprocessing and turned Antialiasing off, and didn't see any difference. What's worse, I turned it back on and still didn't see any difference.

Rebooted, tried again, no difference.

Patch 1.07 has somehow fully disabled antialiasing for me. Anyone else seeing this?

Maybe Nvidea need an update for this extra large patch.

Yes, it looks like antialiasing is gone for good.

I didn't like the in game post-processing anti-aliasing which is why I use the SMAA anti-aliasing forced through Radeon-Pro (with my Radeon R9 280x).

Disabling the SMAA through Radeon Pro disables Anti-aliasing in game (since I have it set off in game) as it should, yet enabling the in game anti aliasing works (not as good as Radeon-pro, but it is a definite improvement).

Hold on..will try other computer with Nvidia 750GTX...

Well the Nvidia GTX 750 Antialiasing did work...but it seems very weak..the fact I noticed it more on the GTX750 might be because of the lower resolution i'm running on.

I would think the post-processing on both the AMD and Nvidia will be identical. So i'll post the AMD shots for now:

The real test would require reinstalling the game and trying an older version; since I use SMAA through radeon pro (you can see the improvement over the built in one on the smaa_on.jpg image), i can't say that I noticed a drop in quality for certain; but it looked almost useless on the GTX750 (though it could be due to the lower graphics settings and resolution on that computer).

AA is fine you are not seeing aliasing rather sharpening is a lot stronger turn it down and you will not see 'aliasing'.

The whole point (or main, at least) of the in-game anti-aliasing was to eliminate the 'shimmer' that GPU forced AA often produces. It's very noticeable (shimmering) on my rig. The problem with the in-game AA is that it came with a price: a frame rate hit. I would guess that's why they removed it during the optimisation.

Hmm, I had no shimmering.
I enabled AA from the Nvidia control panel and it looks fine at 4x.
To avoid the shimmering you should keep antialiasing - transparency on off. I think.

anti-aliasing on my game works but it just completely destroys the performance and makes all graphical settings no matter if its set to low or ultra they all have the same performance as ultra.

This worked. In fact, adding the Withcer 3 to the list of games in the nVidia control panel also brought back the game settings in GeForce Experience, which disappeared with the GFE update last Friday.

Glad to help if I can :D
