OpenClaw users hit CPU fallback with Ollama

A Reddit user says OpenClaw on Linux is much slower than running the same Ollama model directly, even though the machine has an RTX 4070. GPU activity appears during startup and prompt loading, then drops to zero while the answer is being generated, with the CPU taking over instead. The post is asking whether this is a configuration issue or a known OpenClaw/Ollama integration problem.

// ANALYSIS

My read is that this is a setup/debugging post, not a product launch, but it still surfaces a real integration pain point for local-model users.

–The symptom pattern points to a backend/runtime issue rather than a raw model problem: GPU used during load, then CPU used for token generation.
–The likely failure mode is that OpenClaw is routing generation through a different path than the direct Ollama CLI/API flow, or it is forcing a configuration that reduces GPU offload.
–Context-window or session-history overhead may be contributing, especially if OpenClaw is sending large prompts or maintaining long chat state.
–Because this is a user report rather than a verified bug report, the technical cause is still an inference.
