GPU Weights setting ignored for first generation

Nobody has claimed this yet.

Hello,

Everytime I start webui forge or change the model and do my **first** generation, the GPU Weights setting seems to be ignored (even when I modify it before to be sure)

The fix I've found is to interupt the generation and start again

`[Low GPU VRAM Warning] Your current GPU free memory is 223.35 MB for this diffusion iteration.`
`[Low GPU VRAM Warning] This number is lower than the safe value of 1536.00 MB.`
`[Low GPU VRAM Warning] If you continue, you may cause NVIDIA GPU performance degradation for this diffusion process, and the speed may be extremely slow (about 10x slower).`
`[Low GPU VRAM Warning] To solve the problem, you can set the 'GPU Weights' (on the top of page) to a lower value.`
`[Low GPU VRAM Warning] If you cannot find 'GPU Weights', you can click the 'all' option in the 'UI' area on the left-top corner of the webpage.`
`[Low GPU VRAM Warning] If you want to take the risk of NVIDIA GPU fallback and test the 10x slower speed, you can (but are highly not recommended to) add '--disable-gpu-warning' to CMD flags to remove this warning.`

Start by reproducing the first generation after launching the web UI or changing the model, with GPU Weights set explicitly, and compare it with a generation after interruption and retry. The issue provides no file or test entry point; done means the configured GPU Weights value is honored on the first generation and the low-VRAM warning reflects that setting.
