Hi Nenenui
I am not experiencing this issue after 1.5.17.0 SU3 Beta. I am really confused, At release notes it says “Various back-end updates; no user-facing changes” here. I didn’t fly for 3-4 hours and didn’t do a landing test but my fps is not dropping anymore (or it is recovering so fast now) and my mainthread is staying normal while downloading near at my full download speeds (100mbits). Previously, my fps was going down near 15-20fps and mainthread was hammered while downloading, everything was going red on devmode fps display.
Here are 3 videos, quick tests, tested random new airports and planes, also tested Devmode aircraft spawner. Click - Click - Click
edit: is my rolling cache full or something and not caching? I am really confused now, don’t wanna delete rolling cache…
