Title: Windows 8 bug? Poor fps / performance issues (GPU perfectly capable) Version: 3.1.2 OS: Windows 8 Pro Java Version: JRE-7u11-Windows-x64 Description of Problem: Screen flickering, very poor fps drops... what appears to be massive network spikes too yet not network lag just fps lag. First time I launch tekkit it will be fine running at 70-120fps with a HD texture pack no lag at all or network lag... If I close the game and leave my computer Idle for about 20-30 minutes, re-launch tekkit I get 20fps MAXIMUM.. mostly 12-20 fps with a huge spike in the network connectivity graph... the only way I have seen to solve this is to restart, as soon as I restart my pc its fine again, now this is a fresh install of Windows 8, so there is no "interference" I checked tekkit is only using 1GB of ram at most.. and not even half my CPU. I have the latest beta driver from nVidia (the stable driver does not support Windows 8 (it does but not for minecraft anyway because of OpenGL stuff)), the latest Java is installed for Windows 8, the latest Direct X is installed, DX11 copatible GPU's, both GPUS are SLI'ed. Error Messages: There is no error messages. Error Log: ...Or error logs.

Thank you this solved my issue... http://forums.technicpack.net/threads/the-server-gets-an-error.23763/

EDIT: FIX FOR THIS ERROR ... Try this http://forums.technicpack.net/threads/mod_ic2advancedmachines-unsupported-major-minor-version-51-0.2324/ I believe I am getting the same error, the TechnicLuancher works fine, but the server when I extract it and run the launch.bat.. I get the same errors...
