How did you activate TAA in Skyrim? I didn't know it was natively supported.I’ve got TAA active in SkyrimVR, looks really nice and the shimmering is awful without it. The existing AA in Elite is not that great to my HMD enclosed eyes - though the picture is getting slightly better as my hardware gets better I’d much rather a less costly software solution did the trick
By the way Skyrim can be played with internal super sampling as well as SteamVR super sampling. Since Skyrim is not that GPU demanding you can go for 2xSSAA or 400% in SteamVR on a 1080Ti and hit 90 Fps easily.
I bet the lower image is TAA, since it induces a bit of blur. While the upper image's trees seem unfiltered, which are not covered by MSAA (unless it has been specifically adapted to cover transparent textures).I give up. Where is the difference?
