Windows 10 is either a hit or miss for most of us.
I've seen people who have had no issues at all and their upgrade process went 100% smoothly, and everything is working as it should.
But on the other hand, for some of us it's causing a **** ton of problems with certain games or programs, even drivers for hardware that isn't even old, etc
Only issue i have had is that on rocket league the left side of my screen there is a weird color distortion strip that goes top to bottom but it is too small for me to care about, other than that I love windows 10. I had to use 8.1 on my surface and I was reminded as to why 8.1 sucked
If you have screen resolution issues, then you're using a high as **** resolution which is excessive anyway. 1920x1200 works perfectly. The only thing I've had an issue with was installing Logitech Gaming Software, and all I had to do was try again. You're smoking crack if you think it was a bad decision.
