Application Unresponsive
I write this message because I have problems working with Live2D Cubism 4.0, since I get the message that it "does not respond" every few times, and because of this I have closed a file without saving several times.
I observe in my task manager that it is using too much RAM
My specs, are
Processor: AMD Ryzen 7 3700X 8-Core Processor
Memory: 64GB RAM
RTX 3070
I would like to be able to solve this problem and work in good conditions with Live2D please
, thank you very much in advance
