Hello. I'm running Dragon DPI 15.6 on a Dell Inspiron 7000 with an eighth generation I7 processor. I recently found an interesting windows setting in the graphics section, that forces applications to run with GPU acceleration. If my graphics card is an NVIDIA GeForce MX250, would manually assigning Dragon as one of the applications that uses GPU acceleration by default, improve performance? Or, since speech recognition isn't a graphical process, would this be pointless?

I suspect this indeed is pointless when it comes to Dragon. It could probably have an effect if you are working with video editors like Vegas, Filmora, Power Director etc. or photo editors (certainly if files are big), 3D editors, and particularly with gaming.

Thanks, after I posted, I realize the feature was so simple to enable, that it made sense to do an empirical test. What I actually found was kind of strange. Without any graphically intensive programs running, telling Dragon to run in high-performance GPU mode does seem to improve performance (although this could be a placebo effect). However, I have a tendency to run Dragon alongside some graphically intensive software (Zoomtext 2020 & QGIS). In those circumstances, it seemed like the performance of Dragon decreased from baseline. I suspect this is because Dragon then had to compete with the other software for the GPU.  So if you're using Dragon in the absence of graphically intensive programs, there might be a benefit. However, if you're running Dragon alongside graphically intensive software it doesn't make sense to run GPU accelerated Dragon.

I wonder what Dragon is doing that benefits from GPU acceleration? Almost certainly not graphics. Possibly large block copies - although would have to be very large to overcome PCIe lossages.


Related: some of us find that using Nvidia RTX Voice - now NVIDIA Broadcast - for noise filtering helps quite a bit, as in the following thread:

I would be surprised if Nuance is doing that sort of thing in Dragon already.
