Ok. Thanks for your help. I'll post any solutions here once I find any.

Hahah alright. I'll try other ways maybe. But is there any way I could manage to force forge not to reload the default texture pack, and instead maybe wait till minecraft responds itself. 512x512 definitely works. I ran it on vanilla minecraft with no optifine or anything and it runs stablely with 60-80fps with the highest settings possible. It consumes only 500-700mb of ram.

I recently installed forge with optifine on 1.6.4 minecraft because 1.7 is not out yet. There has been a problem for me loading the 512x512 Sphax PureBDcraft texture pack. As soon as I clicked the texture pack, minecraft freezes a while and then it reverts back to the default texture pack. This only happens with texture packs above 128x128. 128x128 works fine. Vanilla minecraft works perfectly with the 512x512 texture pack, it shows minecraft not responding for a minute and then the texture pack loads up. Optifine+Forge+GLSL doesn't work. I do have the GLSL shaders mod installed with the sonic ethers shaderspack. My minecraft has been allocated 8gb of ram and it still reverts back to default everytime I click on the 512x512 texture pack.
