Managed to get some time and setup my G2. I'm still using the GTX1080SC at the moment. (Hoping to pickup the 3090FE on Friday).
The color and resolution just isn't "popping" for me. To be honest, my first flight in the P-47, and I felt like I was still using my Rift S. I'm set at 90hz for the frame rate. I also made sure to set my SteamVR to about 50%, (to get as close to the 2160 resolution as possible). Also, in DCS I reset the PD to 1.0. I do like the adjustable IPD slider on the headset, and adjusted a little via that too.
As I noted, things just don't appear to be a big diff compared to my previous Rift S flights. Yeah, I know, I'm doing something wrong... But I'll keep digging, and I know it'll get better. Plus, once I put in that 3090FE badboy later this weekend... :)
