Better Fps Render Distance Mod FAQ

It's on by default once the mod is installed, so you don't need to enable anything. Just launch the game and your render distance becomes a 3D circular shape instead of a square. If you want to adjust how far it reaches, use the horizontal stretch option.

It appears in the vanilla Video Settings menu as a slider added by the mod. Drag it higher to flatten the circle into an ellipse, which cuts out distant chunks above and below you. If you use Optifine, that button won't show up and you'll need to edit the config file instead.

Optifine replaces the vanilla video options screen, so the mod's button doesn't get added there. You have to change the stretch value directly in the mod's config file instead of through the in-game menu.

It squashes the circular render distance into an ellipsis, so more chunks are loaded out to the sides and fewer are loaded far above and below you. The higher you set it, the less of distant caves and high-altitude terrain gets rendered.

Fly up high or stand on a tall mountain and set the stretch to its maximum, then look at the shape of the loaded area around you. You'll notice the render boundary is round or elliptical rather than a square, and far-off sections below you disappear.

It doesn't remove caves, but a high stretch value means distant cave sections far below you won't be rendered until you get closer. If you're caving and want to see more underground, lower the stretch so the shape stays closer to a circle.

It typically reduces the number of chunk sections being rendered by roughly a tenth to a third, depending on your stretch setting and terrain. That translates into a modest but noticeable FPS gain, especially on lower-end machines.

It works alongside Optifine, but you lose the in-game slider and must configure it through the config file. It generally plays fine with other performance mods since it only changes the shape of the render distance rather than replacing rendering code.

Lower the stretch value back toward the middle or bottom of the range, or reset it to the default. A very high stretch makes the ellipse so flat that nearby terrain above and below you stops rendering, which looks wrong when you're on uneven ground.

No, your normal render distance slider still controls how far the mod reaches overall. The stretch only reshapes that distance into an ellipse, so you can keep your usual render distance and just trim the vertical spread for extra FPS.

It appears as a slider in your video options, but only if you are not running Optifine. If you use Optifine, that button is hidden and you must set the stretch through the config file instead.

Fly up high or stand on a tall mountain and set the stretch to its maximum. From there you can clearly see the render shape flatten into an ellipsis and the lower/higher sections disappear.

That's expected behavior, not a bug. A higher stretch means less terrain below and above you is rendered, so distant caves and deep sections stop showing up.

Popping usually means your stretch is set too high for your render distance, so chunks load in late as you move. Lower the stretch a bit or raise your render distance to smooth it out.

Yes, it works alongside Optifine, but the in-game video options button for the stretch is not available with Optifine installed. You'll need to adjust the stretch through the config file instead.

It typically reduces the number of chunk sections being rendered by roughly 10 to 35 percent, which translates into a noticeable fps boost. The exact gain depends on your render distance and how high you set the stretch.

Start low and raise it gradually until you notice caves vanishing or terrain popping, then back off slightly. There's no single best value since it depends on your render distance and how much you care about seeing below you.

No, it only changes what gets rendered on your screen, not the actual world data. Missing caves or sections are just visual and will reappear if you lower the stretch or raise your render distance.
