Very old screenshot... then StarForge had some type of fps cap (VSync) @ 52.6fps

• CPU can't handle the load of "buildings" correctly: CPU Bottleneck (=engine has to be optimized)
  and / or
  
• Nvidia has to create a real StarForge SLI profile

Unfortunately after installing a new Nvidia Driver, you have to set your SLI Profile again!
Even with the "Express Installation"... :(
(But only the SLI Profile Settings, the tweaked Settings stay the same.)
--> You can "prevent" that by Exporting all customized profiles (with Nvidia Inspector) and import them back after the Nvidia Driver Installation!
