Cap the scale at s <= 448 to avoid saturation?

Nvidia also caps their scale to <= 448 in transformer engine. Their implementation is a little different because they use amax history.

Here is a comparison:

Seed: 10
Steps: 20
CFG = 1
sampler = euler
scheduler = simple
denoise = 1

prompt = Using this elegant style, create a portrait of a duck wearing a pearl tiara and lace collar, maintaining the same refined quality and soft color tones.

The crown stays mostly consistent between the bf16 and capped-scale weights. However this is only 1 comparison
