This issue was introduced in SU2, and it is still present with SU3 BETA, the fps would tank from 80 to 12 for a couple of minutes before it recovers again, happens when panning the camera after it has been still for a couple of minutes, it would also happen when approaching all airports and right before touchdown, the fps would drop and i’m not talking about freezes or stutters, the mainthread would just turn purple for a whole minute and the fps would be 10 to 15 and then it would recover back to 90+, running on a 4090 with 9950X3D, everything is set on ultra TLOD 200 windows 11, this is not specific to an airport or aircraft. Also this wasn’t happening in SU1.
I have the same hardware and I narrowed it down to being a driver problem with the chipset. The driver would mid game shift it to CCD1 away from the 3D cache and it would freeze. I removed the chipset driver with Revo Uninstaller and updated to the latest chipset. And made sure CCPC was set to driver in my BIOS. Haven’t had the issue since. I do get a bunch of stuttering because of the new LOD curve that wasn’t present before. Sadly.
