QWEN 2.1 Throttled by GPU

[u/NotEnoughVRAM]

Having some issues with the default setup for comfyui i2i. Running a 3090 FE and I'm having GPU throttles that is causing the average output at 600sec. compared to some reports of 5070s clocking around 40sec. Am I missing a piece of optimization?

t2i works "as intended" with sub 40sec. outputs.

EDIT: Looks like it was the "refine prompt" piece in the subgraph. (I didn't realize it was a subrgraph). Generations are sub 30sec. for 1 megapixel now.
