I did not find anything wrong in your log file. Please wait for a moderator to assist.

Astalos cause format reinterpretations which are slow, if your computer is powerful enough simply using native 240p resolution pretty much fixes the slowdown but unfortunately for you, you have a pretty old and low power CPU i5-5200U so maybe that won’t work.

I see thanks, i will try it out.
