Sekiro regression in 1.10

[Keelhauled]

There seems to be some sort of regression in dxvk 1.10 in regards to sekiro in the form of stuttering. Specifically at least 1.10, 1.10.3 and 2.0 have the problem but 1.9.4 doesn't. Relevant proton issue ValveSoftware/Proton#2444.

System information

• GPU: Nvidia 2070
• Driver: 525.78.01

How do I reproduce this? The game runs at a smooth 60 FPS here.

From a glance, all the reports i've seen about it are on nvidia.

The stuttering happens everywhere for me.

I was thinking of trying out some of the commits between 1.10 and 1.9.4 but sadly the github actions artifacts have expired. Is there any other source of those old builds?
Also here are my full specs https://gist.github.com/Keelhauled/0411e93dfdb7ab976fb3acd50fb1b314

Managed to reproduce this on my laptop and bisected it to 26381fd.

I don't understand why this only affects Nvidia, this makes zero sense to me right now. There's nothing wrong with this commit and it does not have any unwanted side effect in this game.

So after a bit more digging it turns out that there's frequent memory allocations now because the game is weird, and that's particularly slow on NV.

This branch fixes it for me: https://github.com/doitsujin/dxvk/tree/sekiro-memory-workaround

Thank you, that seems to fix it perfectly.
