Any way to PREVENT 2 'enabled' Shockwave players in Chrome?

gang just a maintenance question: I use Chrome, Firefox, IE10.
I do run into the issue of lousy Flash performance on Chrome if/when multiple instances of Flashplayer/Shockwave are enabled in Chrome.

First, can someone tell me why it is that Chrome does not automatically parse this issue and only allow one to be enabled?

Secondly, what is the RIGHT thing to do in such cases? in the current 'at issue' case I'm looking at, both 'pepperflash' and straight Adobe [just updated] are both installed; one in the user/app bin for chrome settings per-user; the other WOW64 path in Windows. You can see that I have currently disabled pepper and enabled Adobe 'stock' version.
