I was playing Super Mario Galaxy on my laptop this morning and It was playing mostly normal. I usually have some slowdowns in the hub world and bigger galaxies but that's it (I always have my laptop plugged in when I play). During the evening I started playing and It had slowdowns on the title screen and that never happens and It was running slower than usual. For the Config, I have the default settings and for graphics I am using Direct3D 11 and have Skip EFB access from CPU on.
