Solution to Very High GPU Usage afterwards of Premiere Pro 25.2 Update.

[Gaurav25856014nf32]

If you are having very high GPU Usage like maxing out even without doing anything then it could be AI features that came after 25.2 Update and you having old GPUs which doesn't have AI capability. So, simply go to Edit > Preferences > Media Analysis & Transcription > Visual Analysis (TURN OFF 'Analyze all imported media to visually search your projects'). I literally ignored all updates since 25.2 because of this turned ON. I think Adobe should turn this ON by default only to GPUs by detecting if they are capable of AI.
