Spoutcraft is Minecraft with a bunch of mods added to it. Optifine is a part of it but a modified version due to the fact that when we added it the maintainer of Optifine didn't know what the heck he was doing. Spoutcraft will naturally have lower FPS due to the additional mods. Here are some tips and tricks to help get the most out of your FPS. Grinch's Tips & Tricks (Move your mouse to reveal the content) Grinch's Tips & Tricks (open) Grinch's Tips & Tricks (close) Lower the graphic settings! Yes, I know. You can do maxed out options and a high resolution texture pack with Vanilla. Want a giant cookie? This isn't vanilla, its meant to allow you to do more in the game than Vanilla can do. Turn off the minimap The minimap can drastically reduce your frame-rate on older graphic cards. Its highly suggested you turn this off if you have extremely low FPS. Defragment your computer Yes it sometimes is that simple. Sometimes people are too stupid to realize they lag in Vanilla AND Spoutcraft and just assume it is Spoutcraft (Not accusing anyone directly). Defragment your computer and hope for the best! Update your graphic card drivers Updating the drivers will help a lot as usually the company that powers them (Intel, AMD, nVidia) provide lots of fixes/optimizations in newer drivers. Update Java! Update to Java 7, Update 4. Do it! Regardless, I do not think this needs to be a "Spoutcraft sucks" or "How do I improve my framerate" thread. Since the topic is "New Party Frames". On Topic: I'd like to see a more refined/slimmed version of the party frames. They are currently a bit bulky.
