If you’ve stumbled upon this article without reading the previous Minecraft modding tutorial, we’d strongly urge you to jump back and give it a solid read over before continuing. Let’s take a look at the guts of the Optifine menu and break down what the options found therein do. While we can’t promise that level of improvement, we have yet to install Optifine on a machine and not see either the concrete FPS rise and/or the overall performance improve. With Optifine on the default settings it will play Minecraft at 15 FPS with additional tweaking it will play Minecraft at 24-30FPS or so. Without Optifine the computer renders vanilla Minecraft at 3-6 FPS and the game is choppy and unplayable. The ultrabook was made for great battery life and a slim form factor, not serious gaming. Great battery life, great portable profile, but not so great in the GPU department. One of our laptops, for example, is a super slim ultrabook from a few years back. Not only is Optifine great for all computers running Minecraft (Mojang, as much as we love Minecraft, has been a little sloppy with their GPU and graphic optimization code), it can take a computer that barely renders Minecraft and provide a playable experience. While we wouldn’t devote an entire lesson to a single gameplay-tweaking mod, we can’t stress enough how great Optifine is and why you should install it and seriously configure it.
