Thanks for the help on this, I deleted the driver and reinstalled and everything started working as expected.
Now I just need to work out how to get the RGB lights working as they're currently stuck blue and I can't find how to change them
Machine arrived today, eagerly downloaded Mechwarrior 5 from Xbox for PC.
At 1080p with Gforce recommended settings, I am getting 42 fps and massive drops. Others with similar hardware are getting 120+!
Any idea what might be wrong?
