Dedicated server requirements

I’m doing some shopping for development of the dedicated server side for my game and looking for some information.

Say I have a maximum of 10 players on a dedicated server for a multiplayer only game which is physics based like rocket league. Wondering what the specs I should be looking for in a likely windows based vps.

To start I’d likely only be running one server session.

Cpu/ram that’s needed

They say : dedicated server are very low cpu usage. Did you try it?
