FurMark vs Piston

FurMark is a free Windows application for GPU stress testing and graphics benchmarking. It applies a sustained 3D workload to examine thermals, cooling headroom, power limits, and overclock stability. OpenGL and Vulkan rendering paths are available where supported. Benchmark choices include 1080p, 1440p, and 4K presets, along with timed passes. Artifact-oriented checks help identify visual problems such as sparkling or corrupted textures, which may point to heat, memory strain, or unstable tuning. For sensor context, FurMark recommends pairing runs with vendor tools or overlays, including GPU-Z and HWiNFO. Downloads come as an installer or a portable edition that runs from a folder or USB stick without installation. It is aimed at overclockers, PC gamers and builders, reviewers, benchmarkers, and support technicians. The FAQ points to a forum for troubleshooting. Tests should be supervised, temperatures watched, and unsafe runs stopped. The listed plan costs nothing for personal testing on Windows 10/11.

Piston is an Android app that turns a phone into a scanner for vehicle diagnostics. It works with OBD-II and EOBD vehicles through a separate ELM327 adapter connected by Bluetooth or WiFi. The free plan costs nothing and includes reading and clearing diagnostic trouble codes, viewing Freeze Frame data, and reading real-time sensor data. Access is limited to information the vehicle provides through OBD2. Premium adds sensor charts, CSV export, Readiness Monitors, fault history, cloud sync, and VIN reading. Some older vehicles may not support VIN readout. Piston uses Firebase services for crash reporting, monitoring, analytics, authentication, remote configuration, and cloud storage. Settings provide opt-outs for several data services, and account deletion permanently removes associated data.
