Strong disagree there. I just came off finishing Cyberpunk after playing a little of the new SC patch on the PTU yesterday. SC was way WAAAAAY more stable than Cyberpunk. On my 1080ti and Ryzen 2700x I get a fairly consistent 50 - 60 fps at ArcCorp and beyond. Installing on an SSD removes a lot of the loading bugs too. I can get a simple combat mission or trading run, get in my ship, do it, fly back and steal some whale dad's ship for a joy ride without any crashes, hitches or weirdness. This can change if there are a lot of people on the servers though. Which only ever happens during the free flight events such as the one last month where they gave everyone every released ship to try out. They still can't handle more than 50 people well. There's a video I watched that shows the current state of SC. The big difference between SC and Cyberpunk is that Chris Roberts isn't saying SC is done and it's all your fault that the game is buggy.
Oddly enough, Cyberpunk has a lot of the issues early SC 3.0 had before they put in clientside Object Container Streaming, Static and glitching NPCs, weirdness with Elevators, objects not spawning properly, quests bugging out, performance and stability issues. The list goes on. And chaps my ass that the shill deflection is just "get a better PC" when I know my PC is better than at least 95% of the other ones out there. Not flexing here, just putting into perspective how shitty CDPRs optimisation is. You shouldn't need a 3080 just to get a decent sub 60FPS experience.
