The original
OCAT

Replacements
Listings that take over the same core job as OCAT.
FPS Monitor
An in-game overlay for Windows PCs that shows frame rate and hardware sensor readings while you play.
FPS Monitor is a closed-source freemium Windows overlay showing FPS alongside hardware sensors with alerts, rather than OCAT's open-source per-frame CSV capture.
MangoHud

MangoHud moves the FPS and frame-timing overlay to Linux with Vulkan and OpenGL games, adding CPU, GPU and temperature readings, configured through files and environment variables.
