Hey, I got Gears and omg, its seriously the best console -> pc port/game ive ever played. Just excellent.
It has a feature that scales the resolution UP based on performance. (higher performance adjusts the screen percentage at a guess.
Does anyone know if this is an engine feature, or custom?
Thanks 
The editor has a similar feature with automatically lowering the scalability settings when the system is stressing, but to my knowledge this is Editor-Only. Looking at GoW4’s settings and all the system scalability options they have to monitor performance this seems to be a built-in feature for their game. There are some really cool stress testing and other features that they have for the game!
