Tried all options with the current a executable and recent codebase. Worked without any issues!

My only suggestion would be to add /r_drawsunrays just because they're looking neat :)

Hmm, neat in fact. We are running out of space a little but I will see where I can place that.

With f46eda991d1f9667f3a698df712945ee08a522a9 I added the sun rays option to graphics effects menu page an realigned some of the other systems menu options. The switch is working but on my integrated Intel graphics sun rays are not shown to me somehow. However, the switch works. Closing this as implemented.
