Hi Coop,
X-Plane 12.1.2 r3, Mac OS Sequoia 15.1 Beta (yes, I know!), Intel i9, 16GB AMD Radeon Pro 5700 XT.
Terrible stuttering in the Islanders G5, and also in LES's Sundowner V2 (new plane), and your X-Av. 172G5. Probably an unhelpful log attached. I just shut XP down in the flight.
The G5s flashed in the 172 (a bit like the Entegra problem I've had, which we examined a while back), but didn't in the Beech or the Islanders. Those displays are steady, but the stuttering was impossible.
I installed the latest G5 (and G500!) versions - and I had redownloaded from X-Av, and reinstalled to make sure I had the latest versions.
I'm now getting stuttering with any plane! I'm not too sure what has happened. This only started a couple of days ago. It's probably because I was trying out my new Sundowner. I had hardly flown the Islanders in XP12, as I still use XP11 a lot, and never flew the 172 G5. The flashing G5s, only in the 172, is odd, though.
However, after completely powering down my iMac, and restarting, there is no stuttering with planes not using either the G5 or the G500. So, even restarting XP after stuttering with the plugins, something remains in RAM, and everything is not cleared. Cameron has mentioned that Macs have a problem....
