I noticed that UnrealEngineLauncher slows the editor’s FPS from ~37 FPS to ~17 FPS on my MacBook. (UE4 4.2.1-release i5 MacBookPro 16gb ram)
But the Editor constantly re-opens the Launcher. I like the marketplace in the launcher, but if it has this big of an impact on FPS, I don’t want it running unless I specifically open it. So I made this patch if anyone else doesn’t like UE4 opening up the Launcher after they close it.
P.S. Those are the FPS rates with all windows closed, including the toolbar, except the OutputLog so I can read the hitches.
