I've been getting pretty poor performance since I upgraded to Windows 10, not the beta. i5-4670, 8GB RAM, GTX760 If there is more than one planet in the view the performance tanks, maybe 5FPS, even if there isn't really much going on. Graphics settings set to the lowest or highest have no impact to the frame rate. Steam overlay is disabled, no other programs with overlays, nothing of note running in the background. Any suggestions?
