Torch 2.5.0 very low performance

[rsxdalv]

I believe the last working version was 2.4.1

with 2.5.0 I am seeing 10x slowdown and low GPU usage:

    _type='bark',
    seed='2493791119',
    text='test',
    burn_in_prompt='',
    text_temp=0.7,
    waveform_temp=0.7,
    max_length=15,
    history_prompt='voices\\Alice.npz',
    history_prompt_semantic='voices\\Alice.npz',
    long_prompt_radio='Short prompt (<15s)',
    long_prompt_history_radio='Use old generation as history',
    outputs=dict
)

I observe the same issue - torch 2.6.0 is not working, 2.5.0 works but slow, 2.4.1 much faster
