EarthModule

disconsented: Ok, I did the following steps: I started Tekkit from the tekkit launcher, took some debug screenshots while playing, then quit and uninstalled the Tekkit-modpack. I relaunched Tekkit-launcher with administrator rights and re-installed Tekkit-Modpack. When I started playing the first time after install, minecraft crashed (this has actually happened everytime after installing Tekkit-Mod, just forgot to mention). What I figured so far: While playing statistics: FPS is constantly between values 0-9 but average is 0-5. Java is taking around 1.4 GB of RAM while playing Tekkit-Mod. It also takes around 30-60 % of my processing power. Debug Screens while playing first time: 1, 2, 3 (Sorry for the quality, full screen print screens did not work. If you want I can take full screen debug-screenshots after I get some software that takes screenshots while fullscreen is on) While re-installing log (nothing interesting here, I guess) First launch-log after installing (that crashed): according to log it tried to do something with forgeMod before encountering javaException (same one as below). The Log also has numerous warnings and severe warnings like "[WARNING] [Forge Microblocks] Mod Forge Microblocks is missing a pack.mcmeta file, things may not work well" and "[sEVERE] [Minecraft-Client] Using missing texture, unable to load: calclavia:textures/blocks/multiPart.png" Crash-report when first launching after install: Reason of the crash seems to be Java Exception (java.util.MissingFormatArgumentException). On the end of the crash report I found another error: Vec3 Pool Size: ~~ERROR~~ NullPointerException: null Second time launching the game after installing log (Just for comparison with the first one, if someone wants to do that ) Generating new wold -log (Lots of warnings) I guess I can conclude it has something to with installation-process, just can't pinpoint the exact reason.

Thanks for your quick responses to my issue! Curunir: I don't know if IssueTracker is right place, as this has probably more to do with my machine than code. I tried turning my antivirus software off, then ran Tekkit-launcher as administrator and re-installed Tekkit, but problem persists. I'm going to try out Fastcraft and another re-install to produce clean errorlog. I'll let you know if I find something worthy.

Hello! I'm experiencing lag while playing Tekkit in single player survival to the point its unplayable for me. I'm using latest Tekkit recommended build with Minecraft Java Version 1.80.31 (64 bit). No additional mods are used. From Launcher Options I've allocated 5 GB of ram limit for java to use. I tried to change Minecraft-video settings to minimun, but the problem persists. Vanilla Minecraft works smoothly. Any help with this problem is greatly appreciated, I would really want to play Tekkit and conquer the moon! Minecraft video-options I use: Graphics: Fast Render Distance: Tiny Smooth Lighting: Off Performance: Max FPS 3D Anaglyph: Off View Bobbing: On Advanced OpenGL: Off Clouds: Off Particles: Decreased Server Textures: On Use Vsynch: On My computer specifics: OS: Win 8.1 (64 bit) Processor: Intel Core i5-2430M Processor speed: 2.40GHz Number of Cores: 4 RAM: 8.1 GB Video Card: Intel HD Graphics 3000 Video Card Dedicated Memory: 32 MB Video Card Total Memory: 1.6 GB Java Version: 7.0.670 EDIT1: Found Tekkit-Launcher logs for today, they seem to include lots of "GL errors". here are couple of first lines from the log: http://pastebin.com/ECHgrx6Q
