Hey guys. I've used Universe Sandbox 2 for a long time and now when I launched it for the first time in months, I received huge lag and fps was 10-13. It has worked well previously, with that kind of fps present only when simulating thousands of particles at once, and this time I had just started on creating a star, so only 2 planetary objects.... This is weird considering my PC has i7-6800k at 4.1GHz, GTX 1080 SLI at 2GHz and 64GB DDR4 at 2800MHz....

That is certainly most strange. My specs are far inferior and I can still run it at 30 FPS. Have you tried to toggle the graphics and other settings to see if it makes any difference?

No effect. I just tested it further. It seems the bug happens when creating a star, otherwise it works fine. Terraforming Mars, creating binary system for terraformed planets etc. That is a problem tho because I like to create stars on the game and previously I have been able to do that. Perhaps the problem is solved by brute forcing? :D It seems to me as if a certain circumstance causes a logic loop or stuff gets stuck on the pipeline of the CPU itself. I'll have to see once my Ryzen R9 1950X 16 core arrives along with 128GB RAM. I have to wait a bit longer for Volta Titans tho :/

Good to see you've been able to find a likely cause. If creating a star triggers this problem, the actual trigger leading to it should display in your Player.log. If you send your Player.log file to the devs via this email (http://universesandbox.com/blog/2014/08/support-us2/#emaillog), they may be able to do something about it. Perhaps try that before brute forcing it.

Does sound pretty odd that stars would cause that much of a performance hit. Do you notice it in the default solar system simulation which loads on startup?
You can press alt+F to show the in-game FPS at the top of the screen. When exactly do you see it drop? If you create a new simulation and add a star, does the FPS instantly drop?
