            Bug ID: 44141
           Summary: Divinity: Original Sin 2 massive slowdown with shadows
                    enabled
           Product: Wine
           Version: 2.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: wine-bugs at winehq.org

Log file running Divinity:Original Sin 2 with shadows enabled.

Enabling shadows fills the log with:

fixme:d3d:wined3d_debug_callback 0x2377a6a0: "Program undefined behavior
warning: Sampler object 24 has depth compare enabled but is bound to a
non-depth texture, and used by a program that samples it with a shadow sampler.
This is undefined behavior.".

Driver is Nvidia Proprietary, no idea what other drivers say with shadows
enabled. It goes away when shadows are disabled, and framerate returns to
normal.

Possibly related log messages that seem unrelated to shadows being
enabled/disabled:

fixme:d3d11:shdr_handler Unhandled chunk "RDEF".
fixme:d3d11:shdr_handler Unhandled chunk "STAT".

fixme:d3d_shader:shader_sm4_read_instruction_modifier Unhandled modifier
0x800000c2.
fixme:d3d_shader:shader_sm4_read_instruction_modifier Unhandled modifier
0x00155543.

fixme:d3d11:wined3d_depth_stencil_view_desc_from_d3d11 Unhandled depth stencil
view flags 0x3.


Clean wine directory, absolutely no dll overrides.

Attached is a log of running the game to the menu screen with shadows enabled.
The game menu screen has 3D rendering which triggers the bug. A log without
shadows is essentially identical sans the wined3d_debug_callback line spammed
as stated above.
