Skyblock.net is a cool server and I really love it. But Minecraft is really laggy sometimes. So I ask(search) the ultimate GOOGLE to make minecraft stop lagging. Sometimes Minecraft is laggy in the offline worlds too. Minecraft is not laggy for me anymore. WINDOWS So here are the things I use -Minetweaker(I use this profile everytime)(Must Use) -Razer Cortex(This is a game booster. Helps minecraft and other games too) Minetweaker is the ultimate software for Low FPS Issues. You can install forge, optifine by just selecting the list from this software. MAC This is a common issue. You can view the original thread here. While the standard RAM setting of 512 MB initial (-Xms) and 1024 MB maximum (-Xmx) is sufficient for most users, a high-resolution texture pack or installing lots of mods may demand more. To allocate more memory to Minecraft, right click Minecraft.app and select 'Show package contents'. Within the Contents folder open Info.plist. It will open in Xcode, Property List Editor or TextEdit depending on the installed software. In either way, you'll want to find the 'VMOptions' key and change it to your needs. This is how your edited Info.plist should look like in Property List Editor (Xcode) or TextEdit: If this helps you, please leave a Thumbs Up or a Like Button!!
