Use https://buildbot.orphis.net/ppsspp/index.php?m=fulllist or your own builds and bisect which commit exactly broke it(by bisecting I mean just go to half between last builds known to work and broken, in just few tests you will find it).

Most people doesn't use Win 7 anymore and can't even test it anymore due to lack of win 7 support for modern hardware, it's getting less and less compatible with time especially with lower level apis like vulkan.

ppsspp-v1.12.3-263-g712b87ae5-windows-amd64 can't run games. ppsspp-v1.12.3-257-gb3bd06805-windows-amd64 can run games. But popup a dialog when closing.

If click Y, it will popup twice more.

If click N, it will popup a crash dialog.

Thanks, that's good info!

The culprit is then, somehow, this:

• #12108

So it doesn't like creating the pipelines on a background thread, which seems very weird. But something we can fairly easily work-around, I think.

This might be related to this https://github.com/hrydgard/ppsspp/issues/15744?

Unable use Vulkan on Windows 11 either..

@ hrydgard It doesn't only happen in Win7, then need the issue edit the title?

[hrydgard]

@jvhellraiser is that right at the start when starting the game?

[leoxxx]

I found his title display "instance:2", so two processes are running. And this game is 1 player game.

@jvhellraiser is that right at the start when starting the game?

That is correct once you select Vulkan API and load any game error appear.

[hrydgard]

that error is super unexpected. will have to look into it

another one from discord:

I found his title display "instance:2", so two processes are running. And this game is 1 player game. yeah here is one without the instance 2, by the way not to brag about it but i can run multiple ppsspp at once

[leoxxx]

I know PPSSPP can run multiple instances in a PC and 1 player game needn't run multiple processes. I just explain another process is running and your issue is the same as mine.

https://github.com/hrydgard/ppsspp/pull/16256 v1.13.2-1605-gceb4186d0 Can run game, but still popup 2 error dialogboxes after closing. @hrydgard Should I close the issue?

[unknownbrackets]

If we call vkQueuePresentKHR during shutdown for cleanup we probably should ignore errors, even device lost. Maybe a validation error is happening, though.

Does this happen even if you only open PPSSPP, and then close it? Or do you only get those errors if you open a game?

[leoxxx]

Only closing. https://github.com/hrydgard/ppsspp/issues/10646#issuecomment-475105946 2 no error dialogbox. I think I should close this issue and reopen 10646.
