Difference between resolution quality and screen percentage

I was wondering if anyone knew the difference between resolution quality (sg.ResolutionQuality 0 - 100) and screen percentage (r.ScreenPercentage 0 - 100). It seems that resolution quality at 10 looks much better than screen percentage at 10 and offers slightly less performance increase as screen percentage (120 fps vs 70 fps in cave effects demo at 1440p). Also resolution quality 0 looks to be about the same as %50 screen percentage and neither seem to affect a UMG hud. Some clarification would be appreciated.

Up, same question.

You can take a look at the console commands and what their values change by going bringing up the console command window with ~ and entering “r.ScreenPercentage ?” and/or “sg.ResolutionQuality ?”

These will bring up how they work using their tool tip.

You can also see more information about sg.ResolutionQuality in the BaseScalability.ini file in the engine folder.

Have a look all this and look at the output log or the console window when checking values that are being set and how they affect each other.

Thanks man!

Is ResolutionScaleValue related to either of these in anyway?
