I'm using optifine and I tried to turn off fire and portal animations, but it doesn't work. Other options like smooth lighting, minimizing particles, etc work though, does anyone know what might be wrong?
Are you using the latest version?

I'm using Optifine HD Ultra C1 for minecraft version 1.7.10
