You just can't fly DCS or any other credible flightsim without VR these days, it makes all the difference and you won't go back once you tried (and are immune to VR sickness). Just the same as with ED for many, including me. VR here makes all the difference. For DCS, they tested the FA-18 with real FA-18 pilots, and IIRC those said the sim basically behaves correctly, but only VR comes close to the real thing and pancake mode is just cumbersome even with headtracking. Look up C.W. "Mover" Lemoine (I think), there are YT videos about the comparison.
I can understand the guys not being able to run VR thinking it's an exclusive | neglible feature made for others, but then, such stances tend to remind me of the Evil Prince from Shrek 1: "Some of you may die, but that's a price I'm willing to pay". Nice. Losing VR support in ED is a major thing and IIRC unprecedented, a huge step back and just saddening. YMMV.
