I built my own GeForce Now / Google Stadia clone for up to 8 gamepads to connect to the same instance. It's GPU-accelerated, UDP-based and all C++.

It works well and I still use it with friends and family to play games together. I even designed a logo, registered it for an EU trademark, and made t-shirts.

But when Steam Remote Play Together was announced, I decided that there wasn't a market for it anymore, so instead I switched to building real-time AI tools in C++.

My next idea, funny Webcam filters for desktop, was then pre-empted by Snap Camera coming to desktop. With so many FAANG-scale companies releasing free tools, it has become really tricky to find financially viable niches.

How much does it cost for a GPU accelerated VM in the cloud? It would be great if there was an automated way to spin up a VM, install your software and then destroy the VM when you're done. After all, GeForce Now and Google Play don't let you play your full Steam library.

I wonder if there even are a lot of clouds that provide consumer GPUs. I heard GPUs designed for computation doesn't perform as well in games

The dealbreaker is that consumer GPUs (and their drivers) have a terms of use prohibiting various aspects of datacenter usage.

I did not yet try it myself (maybe it doesn't even work anymore?), and it might not be an option for businesses.
