 # Benchmarks
-Welcome to Nova Physics benchmarks
+All benchmarks were run on a Windows 10, Intel i5 6th gen machine.

+Chipmunk2D and Box2D tests are used as a baseline to see how Nova Physics has progress so far performance-wise. All benchmark scenes use the same configuration among all engines; 10 velocity and position iterations, 60Hz simulation.

+Data points gathered for each benchmark includes 30,000 frames and shows how long it takes to simulate one step in milliseconds.
