Again with this idiotic bullshit.
30 FPS is not better in any application in videogames. It may not make AS MUCH of a difference in certain, extremely static games like Hearthstone or something, but come, the fuck, on. Jesus.
If you are incapable of getting 60 FPS on the hardware you're dealing with, that's fine. Say that, and I'll accept that. I'll be ok with 30 FPS locked if you couldn't manage 60 with what you had to work with, but don't lie through your god damn teeth with stupid comments like this just to hide the fact that you couldn't achieve it.
