"Memory_usage" in the CLI during processing and what it means

[dartusf123]

Hello,

10GB 3080 GPU (running at execution_threads=2). Currently processing a 21000 frame video and memory_usage is hovering around 1.2GB. Previous video was 14000 frames and averaged out at 4.1GB. I've also had other videos hover around 2Gb. It's rather inconsistent from video to video. Currently, memory used on GPU Z is at 100% and dedicated GPU memory usage on task manager is also pretty much at 100% (so 10GB total used according to these, but only 1.2 GB used according to the roop unleased CLI).

Few questions:

• What does the memory_usage variable show?
• Why does the memory_usage change from video to video?
• Does the memory_usage variable being low mean overall worse processing performance? If so, how do I get it to reliably stay higher?

Something I've noticed is that sometimes after a few videos or after I've played a game or something, the performance is pretty terrible, so I end up having to restart the computer and performance is back up again. Not sure if this is related or even if I'm correct about that observation.

Thank you for all of your work on this by the way!

memory_usage is ram usage

gpu z show vram usage

if vram filled up performance drops, only need relaunch roop instead of restart
