Threadripper Pro 3990x - can BeamNG utilize 64 cores?

    This is more of a technical question for the development team, I think. The Threadripper Pro 3990x is made primarily for animation and not for games per se. And let's put the price point to the side for this.

    Since I'm constantly torturing BeamNG to the limits and it's always said that the more CPU power, the better, I wonder if BeamNG would be able to fully use the 64 cores if the simulation requires it, or if it just - due to game coding and programming - only uses up to let's say 16 cores?


    Thanks for the insight! Always been wondering :D

    I "think" it probably could as most extra cores past the main 4 that run the game engine (I think) are usually used to run cars. So like 5 extra cars are usually spread across 5 extra cores. 20 cars across 20 extra cores. So on and so forth... so in theory, 60 cores could run 60 cars as if you only had one... if your graphics card can keep up that is.

    BeamNG can use up to one thread per vehicle, + some extra fixed threads (such as UI process, render thread, audio thread, etc).
    How those threads are distributed across the available cores, is up to the OS. Maybe they are distributed evenly, maybe they are not, depends on what the OS thinks is optimal.
    If you only spawn one vehicle, you'll hardly come close to using all cores. If you spawn 100 traffic vehicles, you're more likely that they'll end up landing in all cores or in most of them (again, up to the OS to decide that).

    Thanks a lot for the reply! That being said, there is no limitation from the game's side due to coding or programming? Theoretically, BeamNG can use all 64 cores. Thanks
