I followed the link from Ars Technica above and successfully installed the RTX noise filtering software on my laptop which has a GTX.

No license constraints that I can see, but I would not be at all surprised to find out that some future release of the software refuses to run on my GTX laptop. Which may not be too bad - I have been considering replacing my mortally wounded Microsoft Surface Book to with the Surface Book 3 that has an RTX Quadro. In fact, one of the big things holding me pack from purchasing the Surface Book 3 with RTX is my concern that this GPU consumes considerably more power than the GTX alternative, and my experience so far has been that intermittent fan-based cooling on laptops is not good for speech recognition. This is a sort of test drive.

I think it's highly likely that the noise cancellation may work well, but only in steady-state. But there may be problems when the noise level changes, e.g. in the furnace fans turn on or off.

Too early to tell so far, but I thought I would just provide the link above.

Like I said, too early to tell anything so far, except I somehow "feel" that there is a bit more latency in the recognition. With the Dragon parameters set to as fast as possible.

Q: does anyone have a set up to measure latency from saying something, to text appearing? of course the best way would be from an external sound source, but there might be value doing it just inside the software stack.

This latency is different from the occasional long latency delays or stalls that I have seen with Dragon. This latency seems to be rather consistent with the RTX software.

By the way, I saw presentations on this software when I was at Nvidia. It really does look good.  and although it does seem to run on my older GPU, the newer GPUs do have dramatically increased computational bandwidth, which may translate to reduce latency depending on the workload.
