I love this idea. Such an elegant solution. Hopefully simple.
BTW, one thing I use, even with vorpX, is the excellent FPSVR app available on Steam. I’ve disabled it a few times for testing to make sure it isn’t the cause of any problems (performance or hooking), and it’s never once been the source of any issues whatsoever for me. So it seems like a fairly save bet. It includes a clock. I usually use it in wrist mode except in racing sims.
