I installed the Nvidia DLSS Plugin to implement it in a game I am working on. It is working in the editor, but I noticed that some console commands are not working anymore even if I turn DLSS off. For example r.ScreenPercentage=25 has absolutely no effect. Also trying to set the DLSS-Mode via Console Command in the Cmd is not working at all. For example r.NGX.DLSS.Quality=-2 has absolutely no effect. But I can set it via the DLSS Settings Menu. The performance in the editor is as expected, with DLSS Quality I win performance against DLSS off and DLSS Ultra Performance is saving the most performance.
But it gets very strange if I try to activate it in the game via blueprints. It seems like I can enable or disable it via r.NGX.DLSS.Enable=x because if I disable it, my r.ScreenPercentage is working again.
But it seems not to work changing the mode via console commands in Blueprints. If I try it with the DLSS Node and set DLSS to Quality, I am even LOSING 50% performance against native. I have to set it to ,performance" to reach the same performance like Native+TAA does give me. The picture quality also seems not to be affected much in the game.
I am doing many things with console commands in my main menu. Is it possible, that something interferes with DLSS? At the moment I simply cannot use it for these reasons in my game, very sad. 
- I am losing 50% performance in game with DLSS Quality. WTF?
- In the editor I am winning 50% just how it should be.
- Some console commands seem to be bricked.
Any ideas?
