Overall experience is very good with AMD graphics. Most games run on Steam out of the box. There are also emulators for all the systems I've wanted to use. I use Faugus Launcher for other stores like BattleNet and Epic Games (Magic Arena).
For the most part the games just work, it's more system issues that I've run into where Linux suspend mode and the audio stack can be a little flaky and required Claude to diagnose and sort out.
I've had better luck since the switch to Wayland. I don't play many FPS games but mouse input & overall smoothness for strategy games has been great. Check your mouse settings, you might need to set a higher USB sample rate. Piper is a frontend for adjusting them.
While product often does operate in a waterfall model, I think this is the wrong mindset. Good product management should adopt a lot of the same principles as software development. Form a testable hypothesis, work to get it into production and begin gathering data, then based on your findings determine what the next steps are and whether to adjust the implementation, consider the problem solved or try a different approach.
