Thank you for the link to the LightMass information. Also I noticed one MAJOR thing that I overlooked and then saw it was a conflict with 4.9.x-4.10 was I had EVGA Precision X on and installed to control the fan settings on my EVGA Titan X. Uninstalled it and installed MSI AfterBurner and now I have pretty much no lag in the editor minus the initial “load time” when grabbing an asset from the Kite and Open World assets. I also found out that in Windows 10 Precision X for some reason uses a Graphic Hook that not only caused issues with UE4 but completely blocked access to the ENB graphical mods for FallOut 3/4/New as well as Skyrim. Even when I uninstalled it before I could with the latest build it had to force close some reinstalled Windows 10 Apps/Tiles, think it was Note Taker and something else. When I get back home I will reinstall 4.10 and see if Precision was the issue.
So to anyone having issues with 4.9-4.10 and you are on Windows 10 uninstall Precision X if you have it cause if you don,t you have to Task Manager kill Precision X and the Prevision X Server service running which is way down the list in the advanced view and if you’re not use to killing services with task manager can be a pain. Also if needed I can post this finding as a potential performance issue fix in the AnswerHub/Wiki
