As the gpu unlock project described, Video generation (BF16) speed up +15~20%

Since the install on Ubuntu is very easy now, I tried this tool and run H3 video generation.
System spec:
i7-6700K @4.2G, DDR3 32GB @1600MHz
ASUS TUF 3060 12GB
Ubuntu 24.04 LTS
Generation workflow reference:

0.4M 3:4 (576×736) 5 seconds 24fps
dpmpp_2m_sde + sgm_uniform
pytorch attention
A video generation time decreases from 248s to 190s, improve about 23%.
However the power consumption increased from 150W to 170W at the same power limit setting
sudo nvidia-smi -pl 170Before unlock even set power limit at 187W the maximum consumption was still about 150W.
After unlock set power limit at 187W and GPU run at 187W.
Since the difference I tried to set power limit 150W and test again, it ranges from 200-220s a video about +10~20% improvement.
Summary
Finally do any thing on your own risk, happy generation!
Even nvtop screenshot can be PG-13.
