I wouldn't say the 2080ti is insufficient, it's just that in another sim I play it's a game of inches regarding performance, and I want the very fastest hardware I can throw at it, ie the 3090 and 5950xAMD cpu (once it gets here). For AH3 I'm sure the 2080ti will suffice, and I'll try it shortly to be sure.
I haven't tried the G2 with my remaining 2080ti yet, I'll do it tomorrow and compare it to the 3090.
Eagler, do you mean can you have another type of HMD installed on the same system? The only other HMD I have left atm is my first gen Reverbs, sold the Index and Rift Ss off. I haven't tried to go back to the Reverb gen 1 yet either, but from the docs it says it should work fine. I'd expect the Index would as well, the Rift however, I'm not sure there wouldn't be any conflicts between the Oculus software and WMR.
I got my G2 from PC-Canada Eagler, for some reason Canada got the pre orders first before the USA and other countries. They sent me emails on the 10th saying it shipped, and I got it on Friday after a delay due to a blizzard snow storm in my area.
