switch your monitor to 75 from 85 and you will see it.
I don't see any differences between 75 and 120, or anything in between.
And I wouldn't mind betting some people say they can more out of talking themselves into believing it, like how some people used to tell me 'there really is a huge difference between 32 bit and 24bit colour on my desktop' before they understood what those 8 bits did =]
the lighttubes (pipe thingy with gas in it) flickers at 50/60 Hz.. I really don't think anyone is able to notice that.. :p
It might not be registered in the visuals by your brain per se, but if you stare at it long enough your eyes -will- be strained and you will start getting headaches and such. And it's probably bad for epileptics too.
You would set your res and it was 85hz or whatever the windows setting was.
No it wasn't. I had my refresh rate on 85 but my DX apps popped up in 75.
I'm not a newbie at B3D btw...
Not saying you're new, just misguided. Obviously you had one experience. I had another. I also had an experience of one guy's DX choosing 60 for him.
