-dx12 seems to be broken

[dreimer1986]

Starting a new game or loading a save with -dx12 causes loading to take about three minutes. Then it force closes with:

P.S. Are the WIP Windows builds MSVC2022 Debug or Release builds? These logs look a bit spartanic to me.

Hi @dreimer1986 !

Thanks for report. Apparently newly introduced shadow_resolve pass doesn't compile for DX - looking into it

[Try]

7dbd988 - fixes crash on my machine.
Please don't close ticket, as I need to develop proper solution + add unit test

[dreimer1986]

Confirmed. Crash is fixed. Loading times are quite a bit longer though..

Loading times are quite a bit longer though..

This is probably not related to fix - load time become slower, for the sake of mesh-optimization in 37f7ac68eda50734240b4d96636570adae953604 :D

[dreimer1986]

Naaah, these loading times already were before the fix. Only the crash be gone now is new. As expected ^^

Need to implement masking for DX and probably for metal as well
