It's running 140FPS+ with my 4090 @ 4K, so not sure why you're bringing 4090's into the conversation when you said you have a 3060. Why is 4090 perf relevant, and why are you spreading misinfo about 4090 perf? 😛
The game is in EA and as you said devs are still learning how to optimize for the latest unreal engine. These are things you knew before playing the game. It's good to report perf issues, but you're rambling more than helping.
