I got a laptop but i have no problems with vanilla minecraft and other programs. My video card do it's job pretty well(bf3 on ultra). So problem in the graphical mod(optfine).
^ nope it doesn't work(drivers are updated opengl too)
I got no lags(40+ fps) in the desert, but i got lags in the forest(13-19 fps).
P.S. lol i'm kinda israphel
I got pretty powerful computer(i7(4 cores),2GB video card, 6GB RAM). So it mustn't laging. I played on my old computer(i3, 1GB video card 4GB RAM) with no lags. so it's a problem with one of th mods.
I got a lots of lags in tekkit. But i haven't any lags in vanilla minecraft. So any way to delete optfine(probably it's optfine lagging out my minecraft(im laging when i watching on leaves))
P.S. I'm sorry for my english.
