I fly with Gunslinger52 (above) and as his CPG and as CPG for someone else, as well as and for another regular 2-man team in our Squadron, the CPGs are getting repeated CTDs after no more than 5 minutes. The pilots are not getting CTDs, just the CPGs.
Before my CTDs, I've had the Weapons desync issues and the Waypoints desync issues (first all routes were fully populated with WP1, and then what I had as a waypoint was about "correct" for me, but the pilot saw it about 50km further away). I never got to the TADS/FCR desyncs because we C'dTD too often to get that far.
I ended up each time just flying my own single-crew Apache and I'm not trying CPG until it's all fixed because it's not usable at the moment.
There are desyncs that we've all come to live with/workaround, and then there's this release which is fully broken as a CPG. This is a ridiculous state to push a release out. I love the idea of the new features, but some are best used with two humans, and we can't use them as such. Better to make us wait another "two weeks" than releasing something this regressed and broken.
I've flown as a single since the release and while I've not used CPG seat a lot, when I have hopped in there, it appears to be fine, so as far as I can tell, these issues are for multi-crew CPG seat only.
