I am having an issue with my skeletal mesh of vehicle. I have placed my camera near the mesh for the iron sight view. It works really well in single player but when i start it in multiplayer the nearest mesh texture starts getting pixelated, blurry and quality is dropped. When i move around mesh shows a slight fluid like distortion.
A visual example would help to debug it.
Is your multplayer test on a single computer? My first thought it that running two instances of the app on your machine might have created a performance problem or used up your RAM and some scalability settings are kicking in to reduce resolution. Do you know if you have dynamic resolution or anything like that?
