What happened
A modder attached a Radeon RX 9070 XT as an external GPU to a Steam Machine, achieving over 100 FPS in Crimson Desert on High settings. The setup involved relocating the boot drive to a USB-C port and using an M.2-to-OCuLink adaptor with an eGPU dock.
Why it matters
This is a niche hardware modding feat with little practical takeaway for builders shipping software or AI workloads. The OCuLink eGPU approach may be worth noting if you are exploring compact GPU compute setups, but there is no actionable decision here for most developers or founders.
Discussion angle
Brief mention only: whether OCuLink-based eGPU docks are becoming viable for compact local AI inference rigs, though this article doesn't cover that use case.
