Thank you for bringing DRM-free version of Universe Sandbox, I was waiting for it. Game / program is very good but optimalization isn't so good. I have 110-120 fps in Solar system with 80-85% of GPU usage (1080Ti) and about 45% of CPU usage(i7 4790K) (QHD 1440p and Ultra settings) but after adding Saturn rings 2 times, I have only 60 fps with only ~50% of GPU usage and still ~45-50% of CPU usage. Game does not use performance of hardware. I hope it would be fixed in nearly future. Also font-size is very small in objects-add menu. I scaled up interface to 125% and all buttons icons etc. are good but font-size in some places is very small.
