Lag and Freeze whenever I rotate or move the viewport or the camera

I run all my programs on an NVME storage, I've did full reinstallation as you said, I removed registry and every related file to substance painter using "Revo Uninstaller" but still the problem occurs.

it is for certain not a hardware problem. 

I've also installed different Substance versions to test but no good result.

Are you using a mechanical hard drive or a SSD ?
I can't see any reason why you have such poor performances...

Have you tried completely reinstalling Substance Painter and deleting all it's related files in the registry to do a clean reinstall? 

Have you checked for conflicting applications that you may have on you PC: https://helpx.adobe.com/substance-3d-painter/technical-support/technical-issues/startup-issues/software-conflicts.html
I hope I can help 

any clue?

I updated my drivers but nothing changd, still the problem occurs, here is the video link:

Hi,
Your log isn't very telling. 
Could you record your issue? lagging is quite a generic term, and it would be useful to know where and when it happens, what actions causes it etc. 
Have you tried updating your graphics driver? Or did you recently updated them?
I hope I can help,

Regards,

Hi, 
Would you mind sharing your config? Could you also be a bit more descriptive around your issue? 
It's possible that your issue is related to a Substance Painter limitation where assets with very few polygons have worse performance than denser meshes. 
On your second issue, the one in the log, it's simply stating that some of the fonts that you have on your computer arn't supported by Substance Painter. This isn't a big issue unless you want to use those specific fonts.
Kind Regards,
Geoffroy SC
