--fast issues with Flux

[wcde]

Expected Behavior

Performance boost without errors

Actual Behavior

1. In multi-gpu configuration supports_fp8_compute returns False, optimizations not applied, however main GPU actually support it (I have 4090 and 3090)
2. After force True it works fine, but with loras terminal displays errors in single_blocks from 30 to 37 at each sampling step. Loras themselves work correctly.

Steps to Reproduce

Debug Logs

ERROR lora diffusion_model.single_blocks.30.linear1.weight "addmm_cuda" not implemented for 'Float8_e4m3fn'
