Vive is not very good for DCS due to its low res screens.
I am running the Odyssey+ (had the vive, rift and original odyssey) and the + blows them all away. The Anti-SDE filter does wonders and I am able to read every bit of text and gauge in the cockpits, spot tankers at 23nm and fighters at 12-15nm. My PC is struggling to run it (new build coming) but it is working at least.
the HMDs will only get better resolution over time, but DCS will have issues running them, even on top of the line PCs.
