great to hear! Yes, you can choose speed based on resolution. See the section about "speed and network size" at http://jevois.org/moddoc/DarknetYOLO/modinfo.html
so, if you do, for example,
setpar netin 160 120
you should process at about 695ms/frame (1.4 frames/s). You could also reduce to YUYV 320 240 15.0 in such case. Note that grabbing twice bigger than you will process is desirable as the downscaling by a factor 2 (here, grab at 320x240, then scale down to netin at 160x120) will cleanup some YUYV artifacts (color information is low resolution in this format which only uses 2 bytes/pixel).

the faster you get, the less accurate you will be.
