Choosing the right software for your simulator can be so important if you want to get the best possible experience.
If you are looking to play golf on recreations of courses around the world then I think Jack Nicklaus Perfect Golf (JNPG) and TGC 2019 should be at the top of your list.
For new SkyTrak JNPG is no longer available and so my recommendation is TGC 2019. For other launch monitors and those who are wishing to compete in a full online tour taking part in lots of competitions with tracked stats, world ranking, team events like the Ryder Cup and Presidents Cup then Jack Nicklaus Perfect Golf AND registration at onlinegolftour.net is essential in my opinion.
I've got lots of videos over at my youtube channel showing me playing both each week so please check them out.
