It's not. Been playing 4 years without headlook gear. But I can say that it's a massive disadvantage in A2A combat. You need a decent system for DCS, not necessarily high end but it is quite taxing. Bring decent memory. And SSD install.I've been watching quite some dcs youtubes lately and what I notice is that many use vr, it looks awesome btw, do you guys use vr too and is it a unwritten necessity?
Since I switched from pc to console the only thing I realy miss is a good flight sim and Hotas.
Dcs looks so good that I might even consider buying a pc again, you need a quite powerful system to run this in all it's glory I presume?
And then try out the cluster bombs.
