Ok so I ran across this post a few days ago and decided to try it out. Sure enough the new setting made everything deeper and richer color wise. +1 rep for this!
But then later on I was goofing around with G-Force Experience and it told me that I was not optimized for Elite (the only game I play. Yeah, I'm old and lame). In the past it had said that I was which I found odd but I decided to let GFE re-optimize. Boy am I glad I did!
It turned off the Anti-aliasing, shifted a couple of Highs-Mediums-Ultras and changed the resolution to 1920x1080 from 1200something and BAM! It's like I have a whole new graphics card! Things are WAAAAAYYYYYYYY crisper, tighter and more detailed than ever before. It even looks like there is woodgrain stuff on the dash of my Python. Who knew?
I have been half- looking at upgrading my GPU but I think for now I will stick with my lowly GTX 750. It is serving me better than ever before.
Welcome to the wonderful world of Full HD!!!
