Thanks for the honest reply.
I have no way of telling how many FPS I'm getting, but it's far below 60, that's for sure. My best guess would be around 40 on most courses and lower in the editor.
I did try the mouse swing, but it's incredibly hard to not draw/fade a shot with it, simply because of the way I'm used to holding a mouse.
Also holding down a button and "swinging" with the mouse is not very pleasant for me, so I'd rather not go to using the mouse.
I have not tried other controllers as I do not own other ones, but I do use this controller in other games like FIFA and never had a problem with it.
Again, I understand you're a small team and I know how priorities work, but I'm also a paying customer like anyone else and I currently have a game that's unplayable. I don't mind a challenge (heck, it's the reason I was thrilled there was finally a simulator golf game), but I can't adjust my style of play to "oh, I'll probably get the 89% shot on this hole, so let's club up", you'll understand that's not an option.
I've said this before, but I think a really simple solution would be to give people some form of calibration and/or sensitivity setting, so they can tailor their swings to their likings. Some people might enjoy ramming the stick continuously, whereas I prefer to have a more smooth back- and downswing like the Tigerwoods 13 for example.
Anyway, I'll obviously keep an eye on the patches and try it here and there, but to be completely honest: I don't think the performance will dramatically increase any time soon. Maybe Unity is not up to the task
