Most common issues in UVR

 

- Some models might occasionally disappear from your list (most likely sideloaded outside Download Center) and change their name (probably once they got added to Download Center - e.g. Melband Roformer karaoke ckpt)

 

- Since patch #3, Roformers’ separation times with even smaller overlap are longer than before. Also, remember about inference mode added in one of the later patches. It’s disabled by default as it causes silent separation issues on GTX 10XX GPUs and probably older. Enabling it on newer GPUs might be beneficial for performance

 

- If UVR freezes your PC occasionally during separation, you can change priority of UVR to Idle in Task manager, and the issue is gone sooner or later.

You can force it to be remembered every time you run UVR with Process Lasso (it autostarts with the OS, so you don't have to see the splash screen for a free user every time you want to use it).

- Read for RTX 5000 series issue (if you refrain from using dedicated patch), or use OpenCL (DirectML) in options (slower)
