Looks like deferred context patch isn't really needed. So amount of staging patches basically is now reduced to one. See if removing deferred context improves performance for Nvidia.

Quoting: bekoWill try but I doubt this is related (this time). IIRC I did try this before but it won't hurt to do so again. ty

Follow up: Seems to work much better.

So I'll add gsettings set org.gnome.desktop.interface enable-animations false to my startup script.

So my Witcher 3 worked nicely once as I wrote earlier. I wanted to play it today and now I'll get an error:
err:ntdll:RtlpWaitForCriticalSection section 0x7bd1be00 "/home/user/build/wine-git/source/dlls/ntdll/loader.c: loader_section" wait timed out in thread 002d, blocked by 0009, retrying (60 sec). Any ideas?

The Witcher works still with lutris. I also made some tests with GALLIUMHUD and I don't know what to think of the results. In a village (the very first village) I have FPS around 20-26, GPU load 60 and CPU0-3 40-60. Why doesn't my GPU load go to 100 when the CPU is not limiting? CPU is i5-4440 CPU @ 3.10GHz and GPU Radeon R9 270X (I'm waiting for my RX580).

CPU is limiting, task manager etc doesn't show the whole truth.

Threads are continuously spawned and rescheduled on the different cores. But due to current wine implementation - singleton global shared lock, not enough of them can run in parallel (utilize your 4 cores). This together with a lot of data movement between the GPU and CPU is causing all CPUs to either a) wait for data transfers or b) wait for a mutex to be released (the global lock mentioned earlier). There is a very high activity with patches etc so this might be improved in the future. :-)

Looks like wine-csmt or wine in general is very CPU limited - read: single core performance - when running Witcher 3 at the moment.

I think you are running into this bug.

Reading the bug description, I still don’t know what to do. It seams that it happens only sometimes and it‘s quite rare. I‘ll try to make a new prefix and hope that it helps.

The only major remaining issues now are invisible / distorted monsters (there is a hack patch, but it's causing a freeze for radeonsi), and non optimal performance in general.
