Youthcat Games rebuilt Dyson Sphere Program's multithreading system from scratch, achieving an 88% performance improvement in logic frame efficiency. The new system introduces custom core binding, dynamic task allocation with work-stealing, flexible task scheduling that allows parallel execution of previously sequential logic, and enhanced thread synchronization using hybrid spinlocks. Testing on AMD Ryzen Threadripper PRO 9985WX (64 cores, 128 threads) revealed scheduling overhead and false sharing issues at extreme thread counts, which were subsequently optimized to double frame rates on the same save file.
