Been using a G2 since launch here.
Performance is perfectly acceptable (12900k, 4090), main issue is stability. Most crashes occur at the end of flights or when using the menus during them - which is easy enough to avoid.
Had one very annoying one last night though, just starting my approach after an hour long cargo mission.
Have been using the OpenXR Toolkit throughout, but am gonna try disabling it and see if that makes any difference.
