The median of 10 sample sets is compared against the baseline on the far right side of the table. Multithreaded benchmarks divide the processing amongst the specified number of workers. 5 extra sample sets are run as warmup. All measurments were taken on Intel(R) Core(TM) i9-9900KS CPU @ 4.00GHz with 16 logical cores. Unity Editor version: 2022.3.6f1.
