Hi there and thank you for the report. Are you able to make a apitrace of the game?
Bisected to start with commit https://github.com/doitsujin/dxvk/commit/1b0d2e80c6e4273917c8e49464d51ea57e679b2d
Apitrace that reproduces the issue: https://drive.proton.me/urls/FGCYGJRNZW#zVWvfNiXdWPy
Notice how the trees change appearance depending on if they are on the right or left side of the camera. At least on Nvidia as i haven't checked amd.
Nothing extracted yet.
As of version 2.7 some new rendering artifacts have appeared. A video of these artifacts is posted below. Turning off anti-aliasing seems to remove the artifacts. Downgrading to previous version of dxvk also solves the issue.
Others reported the same issue in the Morrowind discord server. It is seemingly affecting users of both NVIDIA and AMD hardware.
