Was me there started the post.
i upgraded to a Rytzen 7 5800X3D. Plan was to make some test to compare but in my etager i forgot it. But i dont see any change in speed under normal use!
Then i upgraded from a 1080 GTX to a 3070 TI grafic card it was better but not a big different! But then i changed my CPU from a 3,2 GHz to 4,7 GHz i saw a big change of speed. SL only use single core so then Casper Warden. Have only 11% its because it only use one core. But if you messure only the core it would be 100%
my simple conclution is its only rough CPU GHz there makes the biggest change.
