I have been playing Space Engineers without any problems, and I decided to see if it works over RDP and RemoteFX (which provides DX11 over rdp session) but I forgot to enable some options, resulting in non-RemoteFX session. I turned on Space Engineers, and game naturally said "The current version required Dx11 card. If you would like to play blah blah blah blah" I noticed that I had non-RemoteFX session, so I quit it and came back to my desktop to play it. I logged in to my Windows account, logged-in to Steam, and clicked 'Play' button on Space Engineers. Then it would say that my computer don't have DX11 card. I tried deleting and installing the game, and latest development branch, and even as far as trying DX9 branch. Latest development branch said I don't have DX11 card. However, DX9 branch worked. I could even switch renderer to DX11 and it worked fine! EDIT : After using DX11 renderer in DX9 branch, main branch worked. --System Information-- OS : Windows 10 CPU : Intel Xeon E3 - 1231 v3 RAM : 16GB GPU : AMD Radeon R9 200 Series Feature Levels: 11.1,11.0,10.1,10.0,9.3,9.2,9.1 Driver Model: WDDM 2.0 DDraw Status: Enabled D3D Status: Enabled AGP Status: Enabled I can provide full dxdiag if needed.
