--- Comment #20 from Kimmo Myllyvirta kimmo.myllyvirta@gmail.com --- Created attachment 59759 --> https://bugs.winehq.org/attachment.cgi?id=59759 hack for wine staging 2.21
I'll leave this hack here for now. I can try it only with the combat training tutorial until bug 43464 is fixed, and upcoming wine 2.22 needs a different patch.
In short; Tried nvidia graphics debugger. The game is using garbage volume texture in the final steps, which results to black screen or garbage. It needs support for 3d->3d and 2d->3d copy in wined3d_device_copy_sub_resource_region.
