What I did for that ages ago was to limit the amount of buffering to 12-20 packets in the driver using the (now obsolete in the code landing) various qlen_* files, and also disable wmm. At 50Mbits, I typically see 20-60ms latency on my p2p links which is probably close to "good enough" for vnc. But the header of your message had "AC" in it... and at this point, I think going AC is good, regardless of the state of the drivers - you should be able to get 260mbits or more, fairly easily out of that, and so long as you can't saturate it, get pretty low latency, and we do have fq_codel (if not airtime fairness) patches for the ath10k. The DSPs are better. Take a look at the latest ubnt gear. I'm using the indoor uap-lite's a lot and I like 'em. They take to an openwrt reflash really fast. I have not as yet found a suitable replacement for the nanostation M5, but....
