| Metric | Standard PBR | Potato Shader | Improvement | |--------|--------------|---------------|--------------| | Texture samples | 6–10 | 0–2 | | | ALU instructions | 200–500 | 10–30 | 85–95% | | Register pressure | High | Very low | 80% | | Frame time (1080p) | ~8 ms | ~0.5 ms | 16x faster |
| Use Case | Description | |----------|-------------| | Low-end gaming | Running modern games on integrated GPUs (e.g., Intel HD Graphics, old laptops) | | Mobile VR | Reducing fill rate and overheating on smartphones | | Game modding | User-created "ultra-low" graphics mods (e.g., Skyrim Potato Edition ) | | Debugging | Isolating performance bottlenecks by stripping all lighting | | Retro-style games | Intentionally creating a PS1/N64-era aesthetic | 5.
