Ah, my mistake, I took your reference to 'UI' to include the map. I hadn't really noticed a change in the inventory display to be honest.
What's got me puzzled is that, like I mentioned in earlier post, 1.31 also use VRAM hard and eat into the shared memory as well, without the same issues. I guess the clean-up/memory management processes might have changed for the worse in 1.5?
Same, but again, I don't see the delays escalate. Rather they come and go.
Um, did I say I ran without issue at 4k/max settings? No I did not

I've always said I see the FPS drops going into the map. But not all the time, and yes I can (at 1440p) run very happily in 6 GB without any obvious problems for a good while (1-2 hours I guess), and it's not a continuous issue.
It's all academic, in that I doubt we'll be told what the issue was when it's fixed (I'm sure it will be). Judging by how many of us see it (ie everyone using RTX?) and the fact that it's not been quickly addressed in a hotfix like the audio, suggests to me that it's not at all straightforward.
