It has been a long time since I have played Minecraft. The last time I played was around 1.6.4, with the (I believe) Technic modpack and the Sphax texture pack with full modded support. The game worked fine, never had any issues.
At the time I was using a Radeon HD 4650 graphics card. I recently upgraded to a Radeon R7 series graphics card that is much much better than the previous one I was using. Everything that I have played using the new card has worked fine as well.
After picking up Minecraft again and downloading a few modpacks (Yogscast Complete and the DireWolf 20 Packs, both latest versions) the game hardly runs at all. I'm not even using a texture pack yet. I have 4GB or RAM allocated to Minecraft which is fine since my system has 8GB. I doubt that RAM is the problem since previously I was also using just 3GB allocated. The problem shouldn't be the graphics card since it's newer and better in every way than the previous. CPU is the same as before.
Vanilla Minecraft works fine and runs at a stable 60 fps, can go higher but I have vsync on. I was also playing vanilla fine with a 256x texture pack at 60 fps just fine. The modpacks for some reason do not work, even on fast textures with all particles and everything turned off. Is there something I am missing that is completely destroying my performance here or what?
