There is a problem when you do not go to run the second time in the prologue. On day 1, when you go to open the door you go directly to the second running event, but when you return you are in the garden and you can not open the door. Bad
Unreal 5.6 was a performance update where Epic actually spent time optimizing their code for once. CPU usage should be about 10~20% better and graphics 5~20% better depending on lumin usage etc. So in theory, it should perform better... key word is should.
