fp16 is not working (Z-Image base incompatible with RTX 20 series, RDNA2 and older)

Please look at this issue here: https://github.com/Comfy-Org/ComfyUI/issues/12176
This is a dealbreaker for users of GPUs older than Ampere (Pre RTX 3000-series, as well as pre- RDNA3.)
Many users still use these kind of GPUs without BF16 support, and Z Image Turbo still worked with the fp16 hack ComfyUI uses.
I hope this can be fixed.
