Perhapse this might be of help?

System.Diagnostics.Process.GetCurrentProcess().ProcessorAffinity = (System.IntPtr) 4;

Now
$property = "systemname","maxclockspeed","addressWidth",

"numberOfCores", "NumberOfLogicalProcessors"

Get-WmiObject -class win32_processor -Property $property |

Select-Object -Property $property

Will display a lot more information than needed. Once the logical cores are identified by the system is there a way to possibly divide that number in half and then place the value into the string above and have that in the file?

There is no rule like "everything ZOS say is correct". Often what "A" agent says colliding with agent "B"s suggestion. I'm not specialized in that area but as I know from my colleagues (I'm a dev. in QA dep.), above normal is more proper option to give some boost.

I was browsing the add-ons here on EsoUI when I came across this one and read your comment and the funny thing is that I had just read a Zenimax employee say just the opposite about 20 minutes ago in their official forums in regards to people having lag/crashing:

Even ZOS' devs are telling people to set ESO to "high priority".

Setting to High means any interrupt requests by other devices, such as audio, input devices, etc have to wait for ESO constantly. Anyone with ASIO audio will get pops, clicks and jitter out the a$$ with ESO set to High. Mice with 1000hz polling rate will suffer from polling issues. It's fighting with hardware devices for interrupts. The end experience is going to be worse with input lag and stuttery audio. Frametimes will suffer on multi-gpu systems due to the amount of CPU cycles required by them.

Here's something on real-time (which is far worse than High but you get the idea): http://blogs.msdn.com/b/oldnewthing/.../10022675.aspx

Realworld results:

Here's realtime kernelstreaming audio with ESO at High: http://i.imgur.com/HTADBFr.png

Here's realtime kernelstreaming audio with ESO at Above Normal: http://i.imgur.com/9Hkx8qO.png

High was fluctuating wildly between 0 and 900%!! Above Normal was 0% sometimes fluctuating to 10%. In-game the audio was constantly skipping.

This is on Windows 8.1, 4770k @ 4.5Ghz, HD7970 Trifire, Gigabyte G1 Sniper 5, Corsair Force GT 120GB SSD

To fix the stuttering in ESO you have to reduce the affinity so it's not bouncing on cores since the game is largely single threaded. It can balance the load on up to 4 cores efficiently but if the threads are bouncing then the CPU is constantly clearing and filling it's cache. You can also go to UserSettings.txt and change the NumWorkerThreads to 0 to stop this. You can set ESO to Above Normal which enables Foreground Boosting on a Windows OS but don't set it to High.

Due to software interrupts and how CPUs work, I wouldn't really recommend setting the game to High. Above Normal, yes but not High. You are usually worse off with High in games, especially games that are CPU bottlenecked.
