Ok, I want to make this VERY clear. I understand 100% that shaders are very demanding because minecraft was never meant to have them to start with. I am also aware that sues is optimized very poorly and that shaders runs differently for every person (supposedly)

So PC specs

I use amd 13.12 drivers (if i update to the newest ones dxtory runs HORRIBLY and all other recorders i have tried dont give me the nice options dxtory uses... though i may have to start looking again)

cpu - intel i7-4771 3.5ghz

16gb of ram

2x r9 280x with 3gb 384-bit gddr5 (not that it matters, java doesnt use cross fire)

optifine settings

before you say it, changing the render to 16 instead of 32 doesnt change ANYTHING (which is really freaking weird)

So, I'm a bit confused, woudnt a r9 280x run shaders far better then 20 fps? could it possibly have something to do with the fact I "cant" update my drivers to the latest version? Another thing to note, I'm only using 20% of my cpu and 70% of my gpu (acording to msi after burner) and 100% of my second gpu? shoudlnt it not even be using the 2nd one? I'm just lost for words honestly....there is jsut so much that doesnt make sense with my issue that its not even funny

I have a gaming PC that was built less than a year ago and can get up to 500 FPS on vanilla Minecraft. That number drops to 10-60 with shaders. It really is because the game is not optimized enough to handle them efficiently.
