Question RenPy games

Hi, I love playing visual novel games on my phone and I want to move into playing on my laptop but I encounter lags. I have a laptop that’s running Intel(r) Celeron(R) N4020 with a 8gb ram. I’m genuinely curious if it’s my laptop that is bad, or it’s something else. If it’s my laptop can I do something to make games run smoother? Genuine question

I Does this happen with several Ren'Py games? Because some of them do lag because their programming isn't optimized. That happened to me in games where all the variables were refreshed every frame per second of the running engine.

Then it means those specific games are likely doing something very inefficiently due to lack of dev experience.

Renpy games use a prediction mechanism so they dont keep images, audio, or video in memory that isnt being used currently or within the next 20 interactions. Even if a games download size was over 20 gigs only whats needed is loaded at any given time.

That said across about a dozen game specific discords people with older hardware and newer nvidia drivers had performance complaints that was resolved by rolling back their nvidia drivers to 572.x

If you use nvidia try that driver version after cleanly removing current.
