Recently watching direwolfs latest server play series, him and I think CPW where talking about texture packs and he said that texture packs don't affect FPS, however in my experience it seems that running a texture pack does reduce my FPS. Can anyone clear this up for me. Thanks in advance for any responses

CPW was quite right, the small texture sizes used in Minecraft mean that even going from 16x to 64x hardly even makes your video card notice. Modern games have much larger textures; for example, the largest texture size a state of the art Radeon 7870 video card can work with is 16,384x.
However, what CAN reduce your FPS is a lack of memory, both on the CPU and on the video card side. Modern games use highly complex and efficient texture compression, but Minecraft's textures are uncompressed. Therefore, using HD textures makes your memory footprint explode - for example, a 64x texture pack will rapidly fill up my GTX 460's 1 GB VRAM and keep it topped up. Java itself also seems to get more memory hungry; at least, when I run a client and a server on my computer (6 GB RAM) at the same time, I get low memory warnings with a HD texture pack and no warnings with default textures.

I will try and test it in FTB tonight, but I used a x64, x128, x256, and x512 texture pack set before and I did not notice more than a few FPS different between x64 and x512. I've got an NVidia Geforce 680 with 4GB of VRAM, though, so that could very well be part of the issue.
Gods, I'd love a default-like (similar to MineCraft Enchanced: http://www.minecraftforum.net/topic...anced-updated-1220-fireworks-and-magic-books/) texture pack at x256 (x512 and x256 were not different enough for me to stick with the x512).
I believe the issue would be not the amount of RAM you have allocated to the process, but how much VRAM (RAM on your graphics card) as that is what will be saturated when dealing with textures.
Exactly. VRAM is going to be the big bottleneck for this in most people's situations.
