@alessandrogario ok yea there is so much conflicting doco it's impossible to use it. Basically you have to google and hope to find someone else's working config (how I got to where I am now). But if the flags changed then the configs you find in the google search fast become stale. I will try the flags you mentioned. Even just things like flags going in the .flags file and other config stuff going in the .conf file, I kinda worked it out but the documentation was of no help I had to figure it out myself.
