How to deal with time delay when using WebEx remote control? 

I'm trying CTA prep and presentation using two MacBook laptops on the same WIFI hub over WebEx meeting. The time delay is tolerable when I work on the Word document.  But the time delay is occasionally horrible when switching between Word and PPT. 

Has someone tried WebEx remote control between two Windows laptops?  Do they work better than MacBooks for this specific purpose?  Word and PPT are "native" on Windows; and more people use Windows overall.  

Thanks for sharing!
