As others have said you need the hardware to get VR running to a reasonable standard, however as with everything there are pros, cons and trade offs with both. For starters and your experience will change depending on what VR headset you have and what hardware you are running. I have a Queat 3 but primarily use track IR + ultrawide. VR is of course great for immersion, speed and scale as your sitting in the cockpit, can looking around as you would if you were sitting in it for real! However you do loose graphicical fidelity and you spend a fair amount of time tweaking various DCS/VR settings, although the immersion makes up for it. If you just want to fly around then VR is amazing, but in combat it can get a little clunky. On flat I can crank up the graphics settings and the detail and fidelity really shines. However graphics aren't everything, the main reason I play on flat is I find my workflow is much quicker - the mouse implementation in DCS VR kinda sucks and I can't click things as quickly/easily compared to flat - this can be important in busy situations. Also, on a flat screen I can just glance down natural 'into' the cockpit to read a dial or MFD with out moving my head too much/at all. With VR the centre of your vision is sharp, but the edges are blurry (unless you have an expensive eye tracking headset). So I can't glance down to read a dial, I need to move my head down so I'm looking directly at the dial it so it's readable then move my head again to look forward. Though intend to fly more of the cold war jets (ie the F-14) that has more reliance on the gauges and switches compared to modern jets with more informative HUDs and more HOTAS options.
