Also, don't whack everything to ultra as in some cases, the visuals are actually worse than if the setting were set to high
I have textures set to ultra and a mix of high/ultra for the rest with RT off and dlss balanced (make sure you use 2.5.1 version as this also helped improve performance for several people), I'm getting a locked 4k/60fps and at 3440x1440 with dlss quality 100+ fps. There will be traversal stutter especially in hogsmeade or when entering new rooms in hogwarts but as noted by review sites, this happens even on the best of the best hardware, I have found the experience better/smoother on my 4k display tbh since fps is capped to 60, bit weird since fps is over 100 on on the aw monitor but it doesn't feel/look as smooth and no issues showing in frame latency either, maybe something down to animations not playing nice at anything above 60 fps
Thanks, I did clock that. I tried most of the reddit fixes out there with zero benefit, capped the framerate at 60fps like you and found that to be better, but the real gamechanger (literally) was dropping textures to high. I didn't want to do it, but the game is now perfectly smooth with only the very rare dip when loading into a new area etc, but it is completely unrecognisable compared to the horrendous stutter fest I had earlier.
So yeah, if you play at a high res, try dropping your textures a smidge to high to combat those huge dips to the teens when it is running at 100+fps elsewhere. If you are just getting low but steady performance, obviously try tweaking the settings in the video above instead.
And yeah, it does seem like running out of VRAM on a 3080 is indeed a thing at high resolutions. We all knew it should have had 12GB!
