What you actually need.
ART/GTO Solver is a CPU-only engine — DCFR across a multi-core worker pool. Real requirements scale with library size. The Viewer runs anywhere a modern browser opens.
Windows machine
Windows 10 or 11, 64-bit. macOS and Linux are not supported. The engine is CPU-only — no NVIDIA GPU, no CUDA, no driver dependencies. Add cores, get faster solves.
Disk space scales with depth × coverage
Two dials drive your storage budget: how deep you solve and how many spots you cover. Per-spot sizes range 400–800 MB; a full library midpoint sits in the 3–4.5 TB band. A single 6–8 TB external USB-C drive holds the whole thing.
Anything that runs a browser
The Viewer is a self-contained web app served from a one-line local HTTP server. Open it in Chrome, Safari, Firefox, or Edge. It reads .artgto files directly off disk and runs entirely offline once the server is started.
