I have three monitors at home that all have screen refresh rate at 60Hz.
I know that usually when FPS surpasses or is higher than the screen refresh rate, then visual tearing occurs.
However, I found a very mysterious thing... when I was testing, my FPS was lower than 60, the same tearing occurred! The only way to solve this tearing is to use vertical sync.
My question is, usually when FPS is lower than the screen refresh rate, there shouldn't be visual tearing, but how come I still see tearing on my screen???
PS. I can't find the sub-category for monitor display... so I'll just put it in Graphics Cards... sorry.
