It's a hard GPU freeze. It renders input unusable (keyboard doesn't react to any keys). You can still access the system over ssh remotely though, but it's not even rebootable, and you can't restart sddm, because GPU is hanging.

Ahh, yeah forgot you'd mentioned that input was ignored too :/

I haven't seen a freeze like that but I'll run some more tests for you - I'll try it on my Polaris card too :) I've CC'd to the bug report.

Thanks! If it would freeze on Polaris on the same system setup, it would confirm it's Polaris specific bug.

OK - I have seen a game 'freeze' with this patched version of Wine but it's similar as mentioned previously and I can unfreeze it unless the game is set to fullscreen = crashed game but not system.

Happens on save.

You mean with Polaris?

And when it's fullscreen, you can't unfreeze it at all and need a reboot?

No to both, sorry. Just adding FYI.

It's possible the newer kernel is the key solution here. I'll try 4.15 when it will be available in Debian testing.

nope, still freezing.. :(

Hm. It must be an amdgpu Polaris specific bug. Weird, but I hope Mesa / kernel developers can do something about it. So far no one responded in the mesa bug. Once we'll collect more info, I can update it with some details about Vega.

I tested yesterday evening with Vega56 and the patched / hotfixed wine master. I cant use fullscreen due to the loose of input sometimes but windowed it worked. I didnt get a single freeze in about 3 hrs. Will do more testing the next days.

Ubuntu 17.10, mainline kernel 4.15-rc4, Mesa 17.4 Oibaf ppa.

@maspeber: that's likely the game 'freeze' I'm seeing too.

@Shmerl: can you easily compile a later kernel to test?

For reference I installed Win10 on a second disk I had lying around - on Ultra settings (HairWorks off) I'm seeing a solid 60fps @3440x1440 and 100fps @1080p. There's also no slowdown in FPS in town areas - it's very consistent - and the GPU load is showing 100%.

@Shmerl: can you easily compile a later kernel to test?

According to @lod above, newer kernel doesn't help it. Did you have a chance to test it with your RX 480 to confirm the freeze?

I'll update bug report once that will be more clear.

By the way. I saw somewhere that Vega got better GPU reset support, so may be that's why it's not causing a hard freeze but only soft freezes for some?

I dont get a freeze where I had to reboot the OS (like the old wine builds e.g. near hanging man tree). Since 2.22 on sometimes (e.g. after a quick travel) the screen stands still in fullscreenmode and dont accept input from keyboard or mouse. I can alt-tab to the terminal and then if I move the mouse I look around in TW3.

With the compiled master and the patches/hotfixes Shmerl mentioned, I played in windowed mode without an issue (despite the performance) for at least three hours. I will do more testing the next days :)

Did you try the save with rotfiends? It's not about how long you play, but about specific effects causing some issues.

So far I posted in the bugs, that on Vega this freeze is not reproducible. Feel free to add your hardware and driver details there.

sorry, got a freeze with "Moderhäuten" ("Rotfiend")

I played yesterday another two hours without any issue. I fought ghouls, Alghouls, Harpies, "Verschlinger" (similar to Moderhäuten - Rotfiend). Than I wanted to be sure and try your save. I cant read it (I play on GOTY and I think the save game isnt compatible) and than I ported to "Reuseninsel" (the Island with the tower where Y do Keiras (?) Quest with the "Pestae"). I fought 6 Moderhäute and got with the last one the freeze :( I was able to alt-tab to my terminal and exit wine.

Sorry, I play on German so I dont know the English names - but "Moderhäute" should be "Rotfiends".

It is a GOTY save (GOG release).

I think it allows exiting on Vega, because it supports better GPU reset than Polaris. But at least we know now, that freeze still happens. Can you please comment with your findings in both bugs?

This is a great topic, and thanks to all of you who works on this.
I decided to test it with the GOG version 1.31.
- i5-2500K @ 4.2 GHz
- GTX 780 @ 993 MHz
- Kernel 4.14.5
- Nvidia Blob 384.98
- Wine-staging 2.21

Like so many have reported, performance is very weak i have between ~12 and ~18 fps with most of the settings on MAX (HBAO+, Vsync Off).
I have ~20 and ~26 fps with settings on LOW.
My GPU utilization is around ~70% and my CPU ~50%.
It's frustrating when it runs pretty well on Windows. (The last time i tried, about 2 years ago). Except the poor performance, the game looks nice and no bugs or missing textures at the moment.

So it's the Nvidia's fault here and no workarounds ?

Anyway, my next Graphic Card will be an AMD one as i said. ^_^

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.

So I finally had time to check again tw3. This bug still annoys me. If I use dumbxinputemu to get my gamepad to work and override from winecfg the xinput1_3.dll the witcher won't start complaining err:ntdll:RtlpWaitForCriticalSection....
If I don't override the dll tw3 starts normally. I have also tried different wine versions and it always "crashes" if I override it.

If i recall correctly this happens when you copy the 32bit ddls to the x64 bin directory. Make sure you copy the 64-bit dlls ("file xinput1_3.dll" should tell if its the right one.

Not sure if needed here but did you try to copy and override the other xinput dlls as well?
