Requirements for Stock Visual Enhancements so my PC does not freeze.

[Klapaucius]

I tried upgrading my SVE to the high res version, and my computer just choked. 

I was assuming, since I run Premier Pro on this PC and do video editing, that I would be fine.  To be fair, my card is getting old, though I have seen on a few forums that the scatterer may be the issue? Anyway, what are the specs needed to run the high res Stock Visual Enhancements?  

And can someone explain as well the difference between the Environmental Visual Enhancements and Stock Visual Enhancements?

Also, even downgrading to the medium res, I still seem to have lag issues (for some reason whenever I am landing a plane on the runway, just at approach).  I do have a dozen planes parked just off the runway (I've been comparison testing all the stock aircraft and launchers), so that may be contributing as well.

My specs:

 

Windows 7 64-bit

Intel Core I7 3.4 Ghz

16GB Ram

NVIDIA GForce 660Ti (https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660ti/specifications)

KSP 1.4.2 with Making History Expansion

Current Mods:

Planet Shine

Kerbal Engineer

and then Kopernicus and Firespitter, which seem to be required to run the above...
