v 0.5.9 Unplayable

Unfortunately PS crashes as soon as I enter

          Video.OpenGL.UseExtension.GL_ARB_shader_objects = false

into the .cfg file, even if I uncheck VBO.

You could try disabling GLSL.

Tried this and it crashed the client before it could finish loading. Deleted the line and reopened the client...may have made it worse?

it may be a good idea to clear the shadercache after changing that setting - from my experience not doing so and changing that setting may cause crashes/corrupt the cached shaders

This actually did the trick with me here! I manually deleted the file Shadercache (not with the updater) after adding the GLSL disabling line into the planeshift.cfg
Such a simple thing! I knew it! Thank you RlyDontKnow! 

PS has never run smoother than now! Perhaps you can add an option to the updater in the graphics section to disable GLSL in the future?
