I won’t be able to try anytime soon the G2 unfortunately, I’ve been using the Index only for the last 2 months.
If you’re using a headset using the SteamVR compositor (Index, Vive) you can “tweak” the motion smoothing with excellent results down to 6:1. I was using 4:1 before WU3 but have to use 5:1 since because of the perf. Here is a recent post (but search my posts with 22.5 or 18 and you’ll find plenty!)
