What are the minimum device requirements to be able to run this smoothly?

I'm using ROG Zephyrus laptop, i7 core, and Nvidia GeForce RTX, 16GB ram. It's quite laggy for me, took a minute to fall to the ground after spawning. Anything I can do about it besides upgrading? Love the concept though, can't wait for it to be completed!

maybe it's your laptop man i'm playing on an intel core i3 cheap laptop and it runs smooth

[..]

i have 4 gb ram, gt 710 gpu, and amd phenom ii x6 cpu, and game runs smooth with small lags while moving in 4d

rtx *what*? Just saying rtx doesnt mean anything
However check to make sure ur not accidently running on intergrated graphics and not the gpu.

There was an issue with Minecraft, possibly still there, where it gets bad if there is too much RAM assigned to it. Essentially, Minecraft doesn't clear its memory well when given more RAM and, as such, it eventually gets slogged down by the massive amounts of used memory that are not being cleared.

Could be the same, here, given that it is likely a common way to design this type of game. Would make sense why the other guys have less powerful specs and yet doesn't have an issue.

Of course, like the above guy, you didn't specify the exact model of your graphics card. It could be the high end or low end for that series. But... I imagine it would be the high end if you haven't thought of it being a problem, due to your high specs having issue whereas low spec players haven't had any issues.

Meh, who knows until more problems keep being addressed and conquered.
