Just purchased, can’t run rocket league. Opening the game just runs it as normal, on the desktop. Tried all the generic troubleshooting methods; disabling antivirus, disabling overlays, unplugging extra monitors etc but nothing seems to work. Dialog box that says “Attaching to Rocket League.exe” opens when opening the game, but nothing happens.
Please add -dx9 to the game‘s launch options in Steam. Rocket League recently got a DX11 renderer, but the vorpX profile (currently) is for DX9. Unsure yet whether DX11 will be possible, I will check it shortly.
