Nvidia game stream is incredibly robust over the internet. Nothing else even comes close. The latency is incredibly low and the video quality is awesome with almost no compression artifacts like competitors often suffer from. A buddy and I used to stream our home PCs to the office when it was slow and even with both of us streaming at the same time the performance was great. If you weren’t playing a twitch shooter you could honestly hardly even tell it was streamed. This was over a meager 100mbps connection too.

The next closest alternative is Parsec which can manage very low latency, at the expense of significant compression artifacts if your connection isn’t rock solid or your CPU isn’t the fastest.

Steam link streaming is a very distant 3rd, and I actually found that critical components of many games simply did not work. Like for example Unity games where you adjust your camera by pushing and holding a button while dragging the mouse would just not work.

The issue is down to encoding performance, Nvidia performs a LOT better with comparable GPUs.

With that said, h265 is okay from what I've seen, but any devices you're streaming to that use h264 and even a 1060 will stream better than a 6750xt etc
