Any component from 2013 has no place still being used in my opinion we are talking eleven years here.
For instance in 2013 4gb of ram was the average standard in non gaming/specialty pc's. Back then we were still on ddr3 so that ram was also slower. Good luck running more advanced renpy games with that.
The most common processor was still dual core, the Core i3-3220 at 3.3 ghz.
So, i'm probably going to blow your mind here and for this i apologize in advance:
(that's ~25% faster than the i3-3220 you mention. it's from 2014)
I can tell you with full certainty: these RenPy games? They run fine. Heck, Cyberpunk 2077 runs at 40 fps on ultrawide resolution with a gtx1060 plugged into it.
I won't of course argue that new hardware will be considerably faster, but people vastly overestimate the base level that's actually required to run your basic game that uses a framework which wasn't built to rely on the newest, shiniest whistles. (or alternatively, underestimate the level of power they already had at their disposal a decade ago)
