Cyber GPU Stress Test is a compact visual stress testing utility designed for devices like Anbernic RG35XX Plus running Knulli Custom Firmware.
This tool renders hundreds of animated boxes bouncing on the screen to measure rendering performance and observe FPS behavior under heavy graphical load.
- Realtime FPS display as a visual bar
- randomized objects with color and motion
- micro UI lib
- 2 modes (Basic stress test, relax mode ... +2 more in future)
- Fullscreen rendering for performance testing
- Monitor values: FPS, CPU/GPU/DDR temperature
- mini rect benchmark as RECT
- Rust 1.76 or newer
- SDL2 and SDL2_ttf libraries
- Font path (customizable):
/usr/share/fonts/dejavu/DejaVuSans-Bold.ttf
cargo run --releaseTo cross-compile for Anbernic (aarch64):
make build
make deploymake dockerafter make run docker
# cpu-stess-test project builder:
docker run -it -v "$PWD":/cyber-gpu-test cyberfps-debugbuild only in docker:
make buildThen deploy (you can deploy without docker, as option use ssh or smb):
make deployCreate Script cyber-gpu-test.sh and put in anbernic dir roms/tools/
