Xbox Cloud Gaming has had the exact same issues. It was really bad when GTA V and Starfield first joined the service. This is really just a bottleneck in cloud gaming as a market on the whole. The infrastructure isn't there yet and it isn't going to get there overnight. There's also major concerns of power consumption and building the infrastructure itself. It's only been a few years since the massive chip shortages and Xbox has been chastised in the past for losing console inventory due to building up their cloud infrastructure which requires the same components. There's no easy answer of magically having the infrastructure and I don't think Microsoft is further ahead than Nvidia. I also think Nvidia is expecting less gamers than Xbox Cloud Gaming is trying to achieve, so Xbox will have a long road ahead along with Nvidia for making the cloud market a new platform.
