For those that are interested, I finally got chance to try my G2 in DCS. All settings turned up, PD at 1.0 and SteamVR set to AUTO which is hitting 150%. I didn't monitor the frame rates, I just went for the experience and a quick "play" given that I was short on time.
I loaded up a self made practice mission where I start on a busy carrier deck in the F18 with rain, wind, low clouds and other vessels nearby. Straight away, the visual clarity improvement over my previous Rift S was blindingly obvious! I can read every single dial, gauge, label and button in the cockpit with ease. The "sweet spot" compared to the Rift S is also amazing! This is probably because I have a reasonably wide IPD, so I play with the G2 at its max IPD, but I can scan around with my eyes a decent amount and still see clearly. In the Rift S this was not possible at all, I would have to move my head at all times and keep my eyes fixed in one place.
Performance wise I also have no problems at all. The head tracking is perfect, no stuttering and no sign of low frame rates. And this is without turning on any of the beta reprojection options too. The sense of speed as you are launched from the cat and fly low over the water is fantastic from the extra visual clarity gained over the Rift S.
Audio: Wow. I'm very surprised how good it is for a VR headset! I own a set of Arctis Pro GameDac, which sound lovely, so it was a surprise for me to hear good audio from something that isn't even sat on my ears. This, in comparison to the audio of the Rift S was actually one of the biggest differences for me! There are sounds that came from the F18's engines that I would never have heard on the Rift S.
As for the hand controllers, I used these briefly when in the WMR home, and I'm on the fence with them. The tracking doesn't behave so well when your arms are in the down position compared to the Rift S. So I imagine in games where you are "aiming from the hip" this could be a problem, however I don't really intent to play many games that I would do that. I own Half-Life Alyx, so I will be trying this at some point, and I own Beat Sabre - which I somehow can see me having problems with, which will be a shame, so I hope I'm wrong.
All in all though, I'm very happy, because my primary use for this headset is for flight sims, and maybe some driving games. For these, it seems perfect.
