Vulkan Backend = PC freeze

[RemagOrter]

I have a big problem with the Vulkan Backend. It's randomly freezing my Computer when i play Super Mario Galaxy (havn't tried other games so far).
I need to press the reset button on my computer then.

I made screenshots of all relevant settings and stuff:

If anyone could be so kind and look into it, maybe i just have some settings wrong?

Thanks in advance.

Under Graphics > General, try setting Shader Compilation to Synchronous (Ubershader) and then enable Compile Shaders Before Starting.

So a couple of things you can check if that didn't help
-Switch Audio from LLE to HLE. There's really no reason to be using LLE anymore for 99% of games (unless you're using the DPL2 Decoder, which you aren't)
-Graphics > Enhancements:
---Unless you're having graphical issues, you should leave Force 24-bit Color and Arbitrary Mipmap Detection turned on.
-Graphics > Hacks: Unless you're seeing graphical issues, turn these back on
---Ignore Format Changes
---Store EFB Copies to Texture Only
---Defer EFB copies to RAM
---Store XFB Copies to Texture Only
---Fast Depth Calculation
---Disable Bounding Box (especially this one, it can cause slowdowns when enabled in some games, and it's only used by a few games that actively enable Bounding box in their .ini config)

Thanks a lot. I'll try it now and EDIT this later with more input.
[EDIT]
First i have to say, that i have no kind of performance problems. Even with "Shader Compiling -> Synchronous" i barely notice the rarest and smalest hints of stuttering with these settings. Fraps tells me my CPU never goes over 45°C, 2 of 8 Cores running at ~ 20-30% the other 6 at ~7%. GPU max 34°C and running ~ 22-29%. (i7 7700k, GTX 1080 Ti)
So i took my time reading the descriptions of all that settings again and i'm a bit confused and have a few questions. (Because i want the games to be emulated as accurate as possible. Normaly i set the Internal Resolution back to 1x.)

Now i got some questions before i start testing these settings.
1. Audio Emulation. I hear tiny differences if i use HLE, mostly in GameCube games. Does this affect the Vulkan Backend and can be part of the problem?
2.Graphics > Enhancements: I really have some kind of grafical issue if i force 24-bit Color. On my real Wii i have some kind of collorsteps, mostly in the sky or floors and walls. That dissapears mostly. So i would prefer to not force 24 bit color if it's not crash related.
3.If it comes to accuracy, i really struggle with myself activating any Hacks, cause all the descriptions are offering more performance in cost of accuracy and/or few grafical glithes in few games. And as long as these are also not crash related settings, i would love if i don't have to touch them.

But i'll give all these changes a chance. This will take some time, because the crash normally needs few minutes to happen and i need to restart my computer every time.

Thanks in advance.

[EDIT]
OK i tested these settings. and more, cause nothing helped. And my PC still freeze after a while.
I think i'm stuck with D3D11 and OGL.

To try and answer your questions posed:
1. Honestly Audio emulation shouldn't affect Vulkan. If you try Vulkan + LLE and Vulkan + HLE and the crashes happen in both, it's Vulkan. If the crash only happens in one of them, them it's the audio engine.
2. Sounds good. There are some issues with it, so like it said, if you are having graphical issues with the option, then don't use it
3. If a game absolutely needs one of the settings to be turned on or off, it's setup in that game's per-game .ini file to force that setting one way or another. But for a lot of games it doesn't matter one way or another, or they might have slight graphical issues in one setting but not a big enough issue to force the setting. So it just comes down to if you have enough performance overhead to spare. Your computer does, but other computers might not, so if you ever play on a weaker computer, something to keep in mind

Something else you could try would be uninstalling your GPU drivers, and then using the Display Driver Uninstaller (DDU) tool (you can do a Google search for it). This will give you a clean slate to reinstall the latest drivers from Nvidia (probably should download the installer beforehand) that may fix the problem if there's something slightly broken with the way your driver is installed that isn't triggered by anything else except Dolphin's weird usage of drivers.

Thank you for your time. I also spend some time testing alot of things. And i really think your last sentence could be really helpfull, because nothing else helped fixing the vulkan crashes. I'll give it a try now.
Cross the fingers for me.

[RemagOrter]

Ok, i would say this is solved.
I used DDU like you told me to. That way i also got rid of GeForce Experience. I followed the DDU Guide.
I was able to play Super Mario Galaxy now for over 30 minutes without any problems.
Thanks alot for your hint with DDU. After doing countless "New Installations" with GeForce Experience, DDU finally did what GeForce Experience prommissed.
No clue what the problem was, but i´m glad it's fixed now. From now on i'll never use GFExperience again lol.

[KHg8m3r]

Yeah when all else fails, DDU is the last stop before a OS reinstall that could fix it
Glad it worked, enjoy
