I have noticed a few performance related issues with VFX that I'll share with you--I can't necessarily say that this is your problem but it definitely is/was *my* problem.
First, I use an I7 2600k that is moderately OC'd to 3.8k, 16 gigs of DDR3, and a GTX 770 4g video card.
My CPU usage does not increase linearly with the number of VFX viewers I have present. My original setup had 63 VFX on my main screen with 7 VFX sources per client. With all of them loaded, I was getting ~20 fps on my main and 100% CPU usage. No amount of tweaking with the CPU assignments solved the problem. As soon as I hid the VFX, back to capped 60fps. So, since I wanted to maintain all of the VFX, I checked to see if hiding the VFX in windows that were not focused fixed it.
Blam, went from 100% CPU usage/20fps to ~60% CPU usage/30fps. I don't know why, but ISBoxer/Innerspace/whatever was still using CPU to generate those VFX in my other 9 screens even when they weren't the focus window. Now, that still doesn't solve my problem as I went from terrible fps (for me) to only marginally better fps (for me). So, saving a VFX set in your alt screens that only has their VFX sources present and loading that when they're not focused *may* save some CPU for me. I gained considerably (not enough for my personal tastes, but still a major gain).
Going to cross-post this to the VFX forums and see if anyone there has further suggestions. Hopefully it helps you some!
