- Limits of the game is right. - Over about 1000 SPM you need to design to optimize for frame rate and stop using parts like belts and nuclear reactors that require more CPU to simulate. - You can go a lot higher than 1000 without optimizing for UPS, they’ve made a lot of performance improvements over the years. Highly hardware dependent, of course - I have a very high end computer and was able to flirt with 10kSPM but having to move to beltless designs is a real drag. - Is SPM typically considered continuous production without slowdowns forever, or, is there some unwritten rule about needing to maintain +1000 for a specific amount of time? - I can spike to 700 SPM at times, but it only lasts for a minute or two until a resource or two gets completely sucked dry. (Until I get better production, I just pace my research and buffer enough resources to keep research at 100% for a bit.) - It’s meant to be continuous production. Usually this kind of base is left on continuously and people will post the 10 hour production graphs
