Tyler's Frame Machine enables cross-platform benchmark and stress testing via an Open Source and portable utility.
Use it to benchmark or stress test anything you want. If you're a frequent benchmarker, hardware tester, or system builder, Tyler's Frame Machine may just be your new best friend.
It can demonstrate differences between framerates, stress-test machines, and even help you calibrate for live streams. Features include physics objects, spawn rate control, gravity control, resolution selection, windowed mode control, physics framerate capping, global FPS capping, camera movement speed, and more. There's no huge installer, no annoying splash screen, and no crazy list of configurations to get through. It just opens and starts to run - you can change everything in realtime.
ATTO Disk Benchmark is a freeware application that measures your storage system's performance with transfer sizes and test lengths for read and write speeds.
