I can usually run dozens of instances before multithreading and often hundreds once I do multithread with Godot.
I’m curious about your project if you’re having issues. Does it have similar issues in other emulators? Have you tried on real hardware?
I’m getting pretty good frame-rate on at least one of your games. Did you use the version from this website? Did you compile it yourself, and if you did, did you use the --release flags? Do you mind sharing a ROM that has more immediate problems? I’d really like to figure out what is causing these kinds of issue for you in case it’s happening to other people or end-users.
