Ok first, I downloaded FTB on my new computer, which is windows 7 ultimate 64x edition( my dads company gets licenses for it), and 2 gb graphics card and 32 gb of ram. I run FTB with default TP and it is fine for about 2 minutes, and then I get 0 fps and it never goes back up even when it sits there for a full day. I tried it on my other computer with 512 mb graphics card and 4 gb of ram. It still has problems. From the message box thing that it comes up with so you can see what it is doing, it says it is out of memory. Then I installed optifine and it works with hd graphics and text but it still runs out of memory. I also do not know how to get the new TP and the ad don textures to work so I can use both. It is in the same file. Any help is appreciated. My first computer is a new custom build so I am still trying to get everything to work properly.
