The Hotfix yesterday caused me all kinds of issues with VR for a while - but in trying to find the old graphics setup boot option, I realised that I could not find any of the old pre-launch options including Dev Mode. I recall that in the RCs, the new pre-launch menu had an ‘always use this selection’ option - but how do you get the options back and fire up dev-mode (or non-vr mode…)
Go to Steam Library and right click on rfactor2. Open rfactor2 properties and you will find settings for pre-launch menu.
