Drone Autonomy Without a GPU: Why CPU-First Simulation Matters for Decentralized AI
The GPU Gate
If you want to test a drone autonomy algorithm today, the first question is rarely about the algorithm. It is about your hardware.
The best-known drone simulators are built on game engines tuned for photorealism. They assume a discrete GPU, often a recent NVIDIA card, plus a Linux box set up just right. If you have that, they are excellent. If you don't, you are locked out before you write a line of control code.
That gate quietly decides who gets to work on drone intelligence. A student in Sri Lanka, a hobbyist in Lagos, a researcher at an underfunded university: they all have a laptop. Few of them have an RTX workstation or a cloud GPU budget.
I built SkySim to remove that gate. It is an open-source drone flight simulator that runs real physics on an ordinary CPU, with no GPU required. This article is...
