Sorry I'm a bit of a noob, I've been using the same pc for about 5 years. It had an Intel Core 2 duo @3ghz and only 2gb ddr2 800mhz ram with an EVGA 8800gts. I did very little gaming on it. But Within the past week, I've acquired my new pc parts aside from a new gpu, and a new power supply(Although I have one that does the job) In my new pc I have an i7-4790k @ stock speeds and 8gb of ddr3 1866mhz ram. I've downloaded minecraft/Feed the Beast to pass time, and I've noticed, that the CPU Seems to not be able to handle it. I set my render distance to Far (16 Chunks) and I do get around 60 fps, but it seems choppy. I'll get huge lag spikes here and there, and a lot of times, I'll get whole chunks that just won't load. I'll refresh chunks, still no solution. I installed windows on my pc yesterday, and updated some drivers. I do still have the old EVGA 8800 gts I could use. I'm using Integrated graphics 4600 at the moment, and in this https://www.youtube.com/watch?v=q78iWrusgB8 Video, he uses the same processor with the same Integrated graphics, but gets alot better fps, and his chunks load with ease. Also, in the Video, he runs everything on Maxed out Fancy settings, where as I can barely run them on Fast. So I guess my main question is, Do I not have some Driver installed? Or Is it that i'm using integrated graphics? Is my Java not correct in some way? Or is it something else?
