So windows 10...

EDIT


My bootcamp into Window 10 issue got better overnight. Not fully sure why...

Steps I took:

1. Installed Windows normally through the upgrade button, from Windows 7 - gaming FPS was horrible - 5-10 in all games I tried
2. Installed DirectX 9 from an unzippable version because the normal install stops with 'not supported on Windows 10'.
   The desired file is: directx_Jun2010_redist.exe

3. Shutdown system - gaming FPS was STILL horrible.
4. Went over to OSX and installed an August 8 "security" update
5. Went back into Windows 10. Over to:
   Settings > System > About > Device Manager
   Disabled the driver for my Mac monitor (scary) that was called "Generic PnP Monitor".
   - I did this because it was reported as a bad driver that locked brightness to alway fully on, and I guessed that if it had that issue it might have other issues as well...
6. Shutdown the system without testing gaming again. Got up in the morning and on a whim, after making this post this morning, loaded up Guild Wars 2, FFXIV, and Wildstar. All now performed at very high FPS. Problem is solved, not sure which step above did it...

I've wrapped 'code' tags around the link so that you will have to manually paste it in, so people can be sure it is to microsoft...
