Today I'm out of nostalgia for playing Minecraft. (on the latest developer version) I've stated that I have damn little fps although I have a Msi RTX 2080 and a i9-9900k. I really do not know why it could be. Since I partly have up to 45 fps.
RAM released? But even that is unlikely. Play the latest normal version. Development versions are not called that in vain.
So I have partly 32 Gb ram so I do not really think that it is because the PC is not even really old xD
How can you partially have RAM? It's about releasing it for Minecraft. By default, only 1GB is enabled.
In the settings, there's a point where you can set the max frame rate
