 - The slider stops at **10x** even though the runner supports up to **100x**.

 - Speeds above roughly **10x** are useful for throughput, but animation becomes progressively harder to follow visually.
 - At **50x** and especially **100x**, small simulation deltas often round down to **0 ms sleep**, so execution becomes effectively CPU-bound.
 - In CPU-bound ranges, expect higher processor usage and less visually smooth animation than at `1x`.
