[F22-Raptor-2006]

I changed it and then started game and there was no difference. Then I looked at the config file and it had changed back to 1 again!

Mine is slightly different it says:
VideoSetupId=10
Water=1
Effects=1
ForceShaders1x=0

(Vid setup is 10 not 17)
I changed effects to 4 and they changed back to 2 (was originally 1)
