See attached video, VR mode is enabled in all clips but the recording is a screen capture of my desktop display (which shows the issue, but the aliasing is far worse looking through the VR headset).
I have found that irrespective of whether Hardware-accelerated Ray Tracing is enabled or not, if DLSS is enabled it causes significant aliasing. The aliasing goes away if DLSS is disabled.
Interestingly, partway through my testing to capture this on video, when I enabled Hardware-accelerated Ray Tracing, restarted Enscape and then enabled DLSS it started going crazy, not just aliasing.
I'm using an HP Reverb G2 headset, rig is an AMD Ryzen 5800x and RTX 3080.
I've made a log also and have referenced this post.
