I believe these gpus dont have direct hdmi/DisplayPort outputs, so at the very least its tricky to even run a game on them, I guess you need to run the game in a VM or so?
People have gotten games to run on a DGX Spark, which is somewhat similar (GB10 instead of GH200)
In AMD I’ve read it works great, but for NVIDIA chips, in mouse heavy games, it becomes unusable for me.
But I also think that for people that didn't try a "snappier" alternative, it was possible not to realize it's there.
Try and make a comparison with Parsec of even the Steam's own streaming. You will notice a big difference if the issue still exists.
I now remember there was a way to go around it (a bit cumbersome and ugly) which was to render the mouse pointer only locally. That means no mouse cursor changes for tooltips/resizing/different pointers in games, etc. But at least it gets rid of the lag.
