I just read about TGC this morning and have been doing similar searches to find out if my OptiShot (which I love!) is compatible. The best answer that I found on HB Studios' forum was the following, posted in August:
"Once the integration with ProTee is finished(possibly early Oct.), [HB Studios] will work with Any hardware sim company that is interested in getting TGC sim version to run on their devices. Users would then purchase TGC sim license from their respective hardware companies. I.e. Optishot, Flightscope, etc.."
I am hoping DD/OptiShot gets behind this! The launch pad is great for what it is, i.e. no LA monitor, but there are so many areas where the software could be improved: tracking stats such as GIR, FIR, handicaps, having a course designer or interfacing with other golf sims, etc.
I know that a lot of people were disappointed when integration with TW was no longer available. From what I can see, the only addition in OptiShot 2 is going to be the ability to play live, which had been rumoured to be in the product for well over a year. Integration with other applications would be fantastic. I'd definitely fork over a nominal amount to be able to interface with The Golf Club.
