Sampler v5.0 now glacially slow on MacOS

Any reason why this new version (5.0.0) is glacially slow and significantly slower than the previous version on MacOS (M1 Max 32Gb, Sequoia)? UI, selection, scolling is extremely laggy (at least 1 second delay for any drop down or UI element), zoom and pan is extremely stuttery and lags even if only 2D is displayed.
Not hitting any memory limit, still free memory with zero swap.
Sampler has always been a bit chuggy on MacOS but this is a significant performnce decrease.

Out of interest. What would you approximate the time required for this to complete?

hours? days?

 

It really depend of the number of linked asset you have.

Also, the performances of your computer (SSD speed, and processor) have a big influence, the biggest bottleneck possible is an external drive with poor performances like an HDD or cloud storage with on demand files.

Hi,
it should take the same amount of time it did with the previous version.

Hello.

Did you upgrade to the last 5.0.1?

If yes, Substance Sampler will perform again (sorry...) the linking of your stuff.

Regards,

Guillaume

FYI, this issue has returned, it seemed OK for a day but on next open its back to glacial, including UI response even with an empty material . CPU util is around 20% thats it.

Hi,

Regarding your log file, it seems Susbtance Sampler is linking all your content with this update.

You have linked a lot of resources, that is an heavy processing, can take times.

Normaly, when the linking process will finish, you should be back to normal experience.

 

Keep me informed.

Guillaume
