Got so fillipn tired of my system crashing, jumping and running like a dog whilst in ed and VR, that yesterday morning i wiped it all off and reinstalled Win 10, used latest 1803 image, used latest Green team drivers, took 8 hours to redo everything (Biggest thing that took me time was strangly enough Voice Attack, it just would not see my Voice Pack, so went back an edition and works fine).
I must say with all the latest stuff on my VR is double whipped cream smooth and FAST, i can go back to my original 1.25 SS and 2.0 HMD and the rest on fast/ultra and still get no jumps or freezes. Brilliant.
If you have a spare DAY, and you are having issue from too much crud slowing your ED down, just Wipe it!!
