    I have a project that when open in Unity 2019.4 uses 1.4GB of system Ram as shown in the image below:

    Opening the same project in 2023.2 and it uses nearly 3 times the memory, what is causing that?

    I have tried deleting the library folder in case there was any corruption or something, but still its using 3x the memory.

    2023.2 is a beta. Meaning it's probably a debug build of some sort, thus slower and consuming more memory.

    Beta builds are not debug builds, they shouldn't be slower or consume more memory. They are built exactly same way as non-beta builds.

    It's hard to say whether this is expected. It could be a trade off between memory & CPU performance. It could also be a bug. I'd recommend either reporting a bug with a project attached or look at the memory profiler to narrow down what's causing the memory usage increase.
