I’m old enough to have clustered some 16 desktop PCs using openMOSIX a long time ago, before the era of multiple cores and threads.
The whole cluster would function like a single Linux system, automatically spreading the work between nodes.
I used it to run SETI@Home for a bit of fun.
It was a neat idea, but never went mainstream. Soon single PCs were powerful enough to run virtual machines and be partitioned instead of clustered.
I think upscaling is a good idea. Most of the time I’m running around while dodging bullets, arrows or fireballs, so I don’t really have time to examine the details of the foliage around me at the pixel level. I also will not buy an overpowered space heater so that the grass in my game looks more realistic. I don’t want a triple fan monster sounding like a turbojet near me.
