Used to run at a solid 60 in the previous patch (Ryzen 7, 8 Gb VRAM, 16 Gb RAM), but now I cannot comfortably play without FSR turned on, so yes, the overhaul does seem to be quite taxing. Even with FSR on some conversations just have my FPS drop below 20 (in the druid grove, for example).
It will probably get ironed out by the release at the latest, given how D:OS2 EA was barely optimized at all compared to the full version which ran smoothly and crisply.
