After taking a short break from MC I decided to play Tekkit again,
and noticed really weird graphics/outlines on all blocks.
A few screens :
Updated nvidia drivers but the problem still persist.
Tried changing a few in-game graphics options but no changes.
Ran the launcher again due to the cant connect to MC issue.
Not using any custom texture pack or any other mods than the onec included in the Tekkit pack.
Launcher/pack Version: Tekkit 2.1.1
Operating System: Win XP 32bit
Version of Java: Java 6.0.310.5
Description of Problem: strange graphics + outlines on all blocks
Error Messages: N/A
Link to pastebin of log: N/A
Edit : solved
