The latest driver does not work atm. Use 320.49 or an older one.
If the latest drivers doesn't work with the shaders, how do you explain this ?

I believe Karyonix is going to work on that after he finishes Optifine compatibility (assuming the conflict with Optifine can't be fixed by the same modifications he'll make to his class modification code).
Edit: Actually, a hacky way to get it to work is to rename IFP's jar file to something starting with z, so that it gets loaded last. This seems to make it work, but it's not the best solution.
