I'm using mip-map:4
v-sync, unlimited framerates.
fancy, maximum light detail.
I have the setting on my graphics card to:
mipmap set to 2nd highest setting out of 4 settings
and I set the
anti-aliasing to x4 without any anisotropic filtering.
I get no white lines at all and everything renders nicely at locked at 60fps with no screen tears even when shaking my mouse vigorously while staring at animated blocks.
So..... I dunno. The anti-aliasing removes the white lines though, that's what I know.
My graphics card is almost 10 years old, I'm running with 8 mods and my memory usage doesn't go above 400MB used.
goes back and forth between 200 and 300.
Wouldn't say my performance is effected and everything looks nice, no white lines on the grass included.
I don't use optifine either.
Using mipmapping for now
