So yeah, it appears the issue was caused by the Honolulu add-on I had installed. It’s really large, like 24gb. I removed it and went back to the just Waikiki area mod that I had prior that is only like 560mb and spawned at the airport in a couple of spots with no issues. I was looking at the reviews and someone else mentioned also removing the parked planes so it seems it was the mod at fault. Also tested with the new PMDG 737 which is beautiful. Seems the mod was the cause. Even framerates are back to normal now.
