So an IIT doesn’t really have a “refresh rate”, but the thermal component does.
I don’t get any motion sickness with Gen3 IIT’s even moving fast, but with digital systems there’s a latency in refresh rate that becomes very disorienting.
The thermal part of the combined system is digital - in the units I’ve looked at, the image from the thermal is “projected” into the IIT’s lens. So while the image from the IIT alone is lag free, the thermal overlay does have lag and can mess you up a bit.
- some_random 3y agoI should have specified, I meant with the overlay. Do you have any idea what the rate might have been? It's a pretty gucci piece of gear, but in 2008 everything thermal was. A 10 Hz overlay would work fine for observation (those monoculars everyone has now can be about that shitty), but movement would be gross.
- fullspectrumdev 3y agoI have no idea what it would have been back then, but the current “best” ones I’ve seen on the civilian market have a refresh rate of 50hz and you still experience some “issues”. I’ve played with some older kit that was somewhere around 14hz or so and was fucking awful, felt like being ill after walking around in them!
