Honestly the biggest one for me is DLSS, despite the claims of “support for ultrawide”, optimization isn’t particularly great at 5120x1440 (32:9), talking about 40fps avg on medium settings on a 2080ti. I can get it to run at a consistant 60fps if I scale resultion down to 85% but then it effects the visual quality.
Running 2560x1440 (16:9) runs at a comfortable 90fps at high and 3440x1440 (21:9) runs at 70fps also at high.
So DLSS is something that I would aboslutley love to see added sooner rather then later.
