As you notice from the title ive been having some horrible lags issues... i used to play on short with optifine, i would get like 35-40 fps. now for some reason ive had to play in tiny and i still get a crappy 15-25 fps... i dont know why. My computer is HORRIBLE for minecraft... it has 3gb of ram and a AMD Sempron(tm) processor LE-1250 2.20 GHz. my graphics card is a NVIDIA GeForce 6150SE nForce 430. if you know anything about a way to reduce lag or anything about my comp plz help me!
