Using Avorion Client Beta 0.11 r7857
I just got the game a few days ago. I've been experiencing the same issue: FPS drops further and further with each sector change. After closing the game completely and reopening it, everything runs smoothly until I start jumping to multiple sectors again. It's almost as if the previous sectors I visited never unload. The last time the FPS dropped, I just left the game running with my ship sitting in the last sector I jumped to for an hour to see if, maybe, it took the other sectors longer to unload, but it didn't change. Only restarting the game worked.
I am using an older laptop: ASUS G74SX from 2011 with a 1920x1080 screen: https://www.newegg.com/Product/Product.aspx?Item=N82E16834230103
I've noticed with each sector change, the FPS dropped by 2. My starting FPS is between 35 and 40. After 10+ jumps, it stays between 15 and 20. If I stay in whatever sector I logged out from after logging back in, the FPS stays between 35 and 40 no matter how long I stay there with Pirates and Xsotan warping in every few minutes and being destroyed and leaving the debris. FPS only drops with each jump.
