The speaker compiled Doom into RISC-V machine code, first disassembled it using Excel formulas (discovering Excel is Turing complete), then built an ONNX model graph representing a full CPU with RAM as a tensor. The result ran at roughly 2 kHz — one frame every 3-6 hours. The talk wraps with practical advice: when using AI coding assistants like Copilot to optimize performance, always establish a benchmark first, use the rubber duck/contrasting hypothesis feature, and understand that downloaded models may not be optimized for your specific hardware (GPU, NPU, tensor cores). ## Full article daily.dev links to this article rather than hosting it.
