I honestly have no idea, I’m currently on my laptop and doing about 8 grapichs on the scale thingy and not lagging at all. So I’d say people can handle it. Shadows are still a little issue and pain to figure out.
Sir it does affect your game so if you have a good network connection as well as a computer with 8gb ram+ and graphics card then it can handle the amount of lag and fps varies from 20-30
Network connection is not the only causing factor of lag.
Mainly it’s the amount of 3D objects the computer has to render at any one given time. The graphics settings in roblox changes the amount you can render and therefore makes it easier for the PC.
It also does not matter about your graphics card because ROBLOX relies on the CPU for rendering calculations.
I am also pretty sure that ROBLOX is a 32bit program [correct me if I’m wrong] which means it can use up to 4GB ram and no more.
You can use it over 2gb ram as well and in the lighting that volo has shown he has used future lighting where your pic has to render more objects since it chances lighting interface and causes a different reflection. So it needs a graphics card at that point of time.
3.7GB max, with 200 MB reserved for core roblox functions, as game devs we got access to 3.7GB, as a sidenote Roblox on mac is 64 bit, only on windows is it 32 bit.
