that's the answer to that but, what extent do you guys overhold the ender is it, the engine is it primitive component level like render and physics I think we just do what's needed and some stuff is pretty low level some stuff is not let's see overall the engine it's like we've we've had to do some jace mentioned before that we've we've done, instant spline rendering which is not supported in engines that's something that we had to you know create ourselves there's a bunch of, optimization that's like done specifically for satisfactory like the way we we, utilize the unreal engines like replication graph that's also tailored for specif for satisfactory so I guess, and yeah rendering is a big part of that like being able to render a lot of items being able to render the way we do with the conveyor belts and stuff like that like there's a bunch of special things for specifically satisfactory that we have to tailor the engine for
