Bug 1:Spectator mode doesn't do effects on mobs that have an effect

Cannot confirm.
Probably your computer cannot do the shader effects.

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]) here.

Yea Thanks

There you go:

Shaders are not available because OpenGL 2.1 is not supported, ARB_shader_objects is not supported, ARB_vertex_shader is not supported, and ARB_fragment_shader is not supported.

You need a better graphics card for the shader support.

im on an old computer thats why
