If you mean Windows 11 performance then yes but not a lot
It loads faster, takes up a bit less space on the HDD and seems to be less processor intensive
Thats just a gut feel - I have done any extensive testing
I dont run Tellicast on this PC - that runs on a separate Linux box , however I do run all Davids software and all my python scripts on Windows 11 and average CPU usage is around 2% with an I7 processor
