Sorry for taking some time to test this. I have tried running the game as-is in compatibility mode, but it crashes when trying to start a match, only menu works. Fully rebuilding the game in compatibility mode prevents the crash, but the graphics are broken, it would require a lot of changes to make it work as expected.
I’m afraid not. It’s not about optimisation - different renderers require completely different settings. It would be almost like developing two different games.
I have re-enabled the download for version 0.4.0, it contains all of the single player content, uses previous version of the engine and maybe will work, but no guarantees.
