--- Comment #32 from stephematician@gmail.com --- I am not seeing frame rate drops in wine-staging 10.0-rc2, running Horizon Zero Dawn (GoG). Only change has been the update to wine-staging.
I suspected (at first) that this was addressed in https://gitlab.winehq.org/wine/wine/-/merge_requests/3072 - however this has been merged since at least wine-staging 9.5, so there must be some other reason. If I were the type to build wine; then presumably I could bisect between 10.0-rc2 and 9.22 to find the commit.
