I have Windows 11 and the game works just fine in both windowed and fullscreen mode. What does "not work" mean in your case? Does it not start? Does it crash? Is there some graphics issue?

Please enable the LogLevel=debug setting and attach the debug logs (DDrawCompat-Tank.log).

Ok, thanks! I can reproduce the issue now by enabling the ForceD3D9On12 setting. On your system, I suppose it's enabled by default because your Intel driver doesn't have native Direct3D 9 support. See here: https://www.intel.com/content/www/us/en/support/articles/000091239/graphics.html

Even though you also have an NVIDIA GPU, as far as I know there is no way to use that for Direct3D 8 and older APIs. See here: https://nvidia.custhelp.com/app/answers/detail/a_id/3733/~/games-based-on-directx-8-and-older-versions-of-directx-will-only-run-on

Unfortunately, D3D9On12 doesn't work well with this game even without DDrawCompat, so the issue is at least partially on that side, although the artifacts are different than with DDrawCompat. I'll try to improve compatibility with D3D9On12 in the future, but I'm not sure when I'll be able to get to it.

Let's keep this open until I can fix it, so that I don't forget about it.

This particular game seems to work well now in v0.5.0.
