For the most part, I have found that GeForce Now is not bandwidth limited. NVIDIA has spent a lot of time and money tuning the service to do clever dynamic upscaling locally on your machine to minimise the sort of block compression artifacts and frame skipping that you would normally see from say YouTube or Netflix. It's not even particularly latency bound, since round trip times less than 40ms are for most people (unless you're a very competitive player), completely unnoticeable. I've played with latencies at around 60ms and I still find it tolerable (although occasionally a bit annoying). Instead it's very sensitive to network jitter. Even 1 or 2 ms of random jitter can dramatically reduce the quality of the service. And given the distance between your local machine, and the number of hops required between your device and the server, there's a lot of room for random jitter. Part of the problem can be mitigated, by carefully ensuring that everything in your home network is dimensioned properly. But the rest of the pipe is owned by your ISP, and they could apply all sorts of dodgy QoS parameters that increase your likelihood of experiencing jitter.
