It is not particularly surprising that the performance isn't great with WebGL disabled. After all, that's why we took the time to create the WebGL particle layers in the first place - to improve the simulation's performance. So I don't particularly feel like any action is necessary on this, but I'll assign to @ariel-phet to make sure that he concurs.

agreed @jbphet, I don't think any action is necessary, Webgl should generally work with Edge, unless the graphics card is black listed (you would think that would be less likely with Win 10 computers).
