nvsvc32.exe is in reference to your nvidia drivers.
taken from a microsoft securities website:
"In regards to csrss.exe, It can be a virus, but it is also a Windows file. As a windows file, it can consume a high % of your processor if you enable hardware graphic aceleration"
Tekki, if theres a way to reset whatever you did to your nvidia card, please do it. I'm also concerned that you told me you adjusted your registry settings to maximize ffxi. Best case scenario is that you can revert your settings, worst case scenario is that youve changed your registry settings beyond a point of recovery if you dont know what was changed. That leads us down a path of backup/wipe/reload.....
Since we both play on a notebook with identical cards, I can help you adjust your graphics settings to run in high resolution without using system resources.
Let me know.
