I recently bought the Gear VR (using it with S7 phone) and just discovered the Trinus VR... what's the current status of LFS compatibility with Trinus VR?
Yup, that's the way it goes. Or you can download it first, and it'll run in demo mode until you buy the license and unlock the entire content. There's lots of info at http://www.lfs.net/ about the procedure.
I have 2GB of RAM, and my fps went down from above 100 to below 50 (even below 30 at times) when changing from 32bit WinXP to 64bit Vista. I also have no sound in LFS (test patch U) with Vista. I will probably be trying 64bit XP soon, will let you know how it goes.
