Live2D Severe Lag
in Help
As soon as I open the program, I have severe lag. I have this lag before I even open a file, and across versions. I have tried both 4.0.06 and 4.0.05, and had the same issue. I have increased the amount of RAM the program can use, updated Java, and my own drivers, and cannot figure out what the problem is. Any help?? This is my first time using the program, and it does not make me hopeful.
I have a GeForce RTX 2070 Super and 16GB of RAM

I noticed some lag spike today when I opened up a project, but it was my CPU spiking, not Memory.
