Not sure how much that changed in the last 2 years, but this is a check from german office of statistics from 2020:

Isn't it enough to just change the description file? All other files should be identical if I'm not wrong. So instead of loading the whole course it should be enough to change just this one file. But really not sure. I think I read something like that somewhere

Just watch your snap. If you keep missing it then the resolution may be the reason. In this case you should go down step by step until the snap is back again. We had this problem several times. You can also try to go down in quality, from Ultra-High to high etc.

The private tab was also ment for the official Golf Clubs (http://social.perfectparallel.com/) which never really got online because the API didn't work. Once we created a tournament it effected the OGT Tournaments. As so many things, Andrew never fixed the problems :(

You all know PG balls have an iron core and bunkers and water traps are magnetic in PG? Thought everyone kn0w this :D :D

they also have mouse swing. No 3click but RTS I think.

I know for sure we had some courses with restrictions, Augusta was one of them, the first course had to be renamed. Not sure if something changed meenwhile but TPC Sawgrass is a PG course and they didn't have the right to use the real name.

Maybe something changed with the user created courses ...

Name restrictions by the golf courses. If they don't allow to use their name there is no way to do so.

steam seems to have some lag Problems what can cause jittery swing meter. Other games are also effected, mainly ego shooters etc.

This might be a steam thing. If steam doesn't synchronize (PG) Data this happens. I had this some weeks ago and at start steam told me the sync is not available. Also steam seems to have some lag Problems what can cause jittery swing meter.
