My computer has been preforming very poorly with BeamMP at about 15 fps when I join large sessions that has more than about 10 players.
I have a laptop with a ryzen 5 4600H and a 1650ti, and with 7.4 gigs of usable memory.
Can a memory upgrade improve performance, and if so, will upgrading to 16 gigs be enough?
Does it work on Intel(R)graphics but outdated and Intel core I3
It wont hurt, but you are not going to see a massive improvement
4600h has 6 cores, so anything over 6-8 people you will start to experience lag. Make sure and keep your laptop cooled as well for optimum performance
Beamng is very CPU intensive, it is a rule of thumb to have 1 CPU core per player. You are calculating everyones physics (suspension movements, aerodynamics, crash physics) so with more people comes more things to calculate.
