PerfBar - On-Screen Performance Overlay for Jailbroken PS5

Version 0.1.2

A standalone on-screen performance overlay for the PS5. It draws FPS, frametimes, 1% lows, CPU/SoC temperatures, and RAM/VRAM usage directly over your games.

Why this exists

If you've tried using the built-in performance bars in etaHEN alongside kstuff, you know they often fight over kernel control and cause instant kernel panics.

perfbar was built to fix that. It is a completely standalone payload. It does not require any other payloads, and it does not fight with any other payload for kernel memory. You can run this alongside your normal setup without causing a System Software Error.

⚡ How to use it

1. Send the PrefBar-complete_VX.X.X.elf payload to your PS5.
2. Start a game.
3. After roughly 5–10 seconds, the overlay will appear in the top-left corner.
