I would like to take a moment to gripe about Steam's 2-hour refund window when it comes to modern open world story rpg's, in that by the time you get past chr menu (even if you rush it/don't care), fancy game logos, long intro cutscenes, long tutorial bits (I can't even manually save yet), alter settings multiple times, restart game to make sure settings take, etc. it's going to 3+ hours or more and one sometimes gives up on the idea of a refund for that reason alone. The actual Hogwarts castle is likely going to be a performance drop for many and I think you don't reach that for a while.
That gripe over...at the very start of the game, here's what I see, using 2080ti, 9900k, 32GB, no overlays except an fps counter:
--during the pre-shader caching/setup whatever it is, which takes a few minutes, system ram went up to about 15GB for me, so not counting Windows maybe 12-13gb? I forgot to glance at task manager for ram usage after that. >.>
---4k, Ultra, no DLSS/scaling, no RT---
first cutscenes and area you can walk around in (not full open world yet), 35-45fps
----4k, Ultra, DLSS at Quality, no RT---
goes up to 50-60fps, DLSS to me looks noticeably softer but still all right
---1440, Ultra, no DLSS/scaling, no RT---
first cutscenes and area you can walk in, 50-60ish fps
---1440, Ultra, DLSS/Quality, no RT---
90-110fps
...I tried reducing settings but I sort of felt like not everything was registering within game without a restart, would have spend an hour fiddling with that. But just changing one setting, like shadows, down a notch or two didn't seem to make much difference in 4k. I did try -all low- and graphically it's actually not the worst I've seen, although the fps increase didn't seem mega substantial for it.
Debating whether to waste more refund window on testing. 😛
