Launcher Version: 1.0.1.3

Operating System: Windows 10

Java Version: dunno

Antivirus Program: I can see trough almost every wall and floor, they're all invisible. Also trees are on a different hight or are floating in the sky, textures are messed up (I can see sugar can laying flat on the ground). This all happens when I loaded the world. But before, it never happened. This is in Tekkit btw.

You're using a version of Windows from the future. There's your problem.

In all seriousness, it's probably an OptiFine problem. Get the version of OptiFine Standard that matches whatever Minecraft version your Tekkit is running (probably 1.2.5), and drop the contents in the appropriate modpack.jar with 7zip or WinRAR.
