I’m really surprised I haven’t had any major framerate drops in TotK. I’m using my launch-day system, so as old as they get, and playing hand-held almost exclusively it’s been pretty darn smooth.
That’ll be your retraction settings that need to be tuned. The pressure inside the nozzle isn’t getting high enough when starting a new layer. Took me a couple minutes to see the issue since it’s black and shiny. I’ve used retractioncalibration.com before to help get my retractions tuned
I don’t do it for every spool, but I’ll generally tune for each brand I have. Elegoo’s PLA prints different than IIID Max PLA+, so I have profiles for both. I’ll only tune a new spool if it’s not printing well with the brand’s profile
