Any difference between PNGTuber+ on Steam from other download methods? +Question about desync/delayed issue

Hey all, for reference I have been using PNGTuber+ for a while and really like it. However, recently when playing some guys the audio will be delayed.

Today I noticed that PNGTuber+ is on steam, so I am wondering if I should get that version for consistent updates compared to just having it downloaded on my drive.

Would it cause problems to have PNGTuber+ running through Steam while another game may be loaded? Or is it better to have it directly downloaded from where ever I downloaded it from? Just wondering.|

Edit: There is another issue that I didnt mention in the question but feel bad if I make two posts about my issues so soon. On another note, sometimes during some games the PNGtuber itself will be laggy and freeze. Would this be a problem with CPU? Or is there something I can do about it?
