What do you mean, you cannot alt-tab back in? What actually happens?

Please also try the latest master version of DXVK. You cna find a build here: https://github.com/doitsujin/dxvk/suites/6067454616/artifacts/209680631

The game minimizes to the task bar and continues running, but I can't tab back into the game. Neither clicking it from the task bar or alt-tabbing will maximize it. I have to kill the process to close it and restart the game. I just tried the build you linked and unfortunately it does the same thing.

Does it help if you make a file called dxvk.conf next to the exe and insert d3d9.enableDialogMode = True ?
To make sure it's picking up the conf file you can enable the hud in it also.

Sadly that did not help. I enabled HUD as you suggested to confirm it's reading the conf.

I remember not being able to alt-tab while using d3d8to9 and dxvk either, with the original 32-bit version of the game (which only has d3d8 support). And it doesn't provide a non-exclusive or windowed fullscreen mode to work around the problem, sadly. I always thought it was a Wine problem, since AFAIK WineD3D also doesn't handle alt-tabing here very well.

Edit: Just FYI, alt+tabbing now works fine in Wine, so it looks like it's a Windows only issue.

Edit: actually nevermind didn't realize you are on Windows 7 so no new changes will work here.

Please reopen in case the issue exists on Windows 10/11 or Linux.

It still happens on Windows 10 21H2 and DXVK version 2.1.

Please test the very latest master and set up a config file with the contents: d3d9.deviceLost = True

Sorry, by latest master you mean 2.1? I tried with d3d9.deviceLost = True and I still couldn't tab in.

Sorry, by latest master you mean 2.1?

No, I mean the development version as of 20 minutes ago.

Thanks for the link. Now when tabbing out, the game gets stuck on the last frame before tabbing out. If I try to alt tab again the game minimizes. If I try to maximize the window, the game crashes.
