this is just rubbish, the difference in a new route made from scratch with UE5 and in comparison with UE4 is day and night, really. look at the bus in Berlin it has unbelievable graphics with UE5 and costs less then one route add on in tsw.
So you are also okay with performance being much worse. Ue4 already struggles performance wise. Ue5 with lumen and nanite require even more graphical power which means more memory usage and therefore worse performance.
here the thing i was trying to find tutorials on making projects on you tube but it getting harder to fine now since alot of it on unreal 5. and yes i try making project using unreal 5 tutorials video for tsw unreal 4 but it won't work.
