Optimizing for mobile, disable post processing completely

I thought when I chose low quality when creating my project Unreal Engine would disable ALL post processing. But the GPU Visualizer says post processing is still going on, specifically “Tonemapper#3 FramebufferFetch=0”. Is this a necessary part of the engine or can I disable it? I know it does not look like a lot, but on really weak phones it could make all the difference, especially since the game is currently unplayable on my LG android because of the slow framerate. Any help appreciated!!

Hi Zach,

As far as I’m aware the tonemapper cannot be fully disabled, but you can try using the console command ShowFlag.Tonemapper 0 to see if it is disabled for you in your packaged game. If not, then you’d likely have to make some code changes, but I’m not exactly sure what would need to be disabled and if it would have farther reaching repercussions for doing so.

I’m fairly certain the ShowFlag commands are editor only, but I could be mistaken.

I’ve tried this. It works in editor and in launcher, but not in packaged game.
