Reply to comment by WeirdGamerAidan in ELI5: Why do computers need GPUs (integrated or external)? What information is the CPU sending to the GPU that it can't just send to a display? by WeirdGamerAidan

After posting my reply I considered I might have been incorrect in what I assumed from your comment, so I apologise. I assumed you were talking about when a game doesn't select the dedicated graphics and defaults to the integrated graphics on the CPU, which is quite common and would lead to low frame rates. I've never actually heard of a CPU skipping the integrated graphics and directly rendering a game, which sounds interesting. What does it appear as in your task manager?

When it happens, as soon as I load up the game cpu usage skyrockets to 100 and gpu stays low, and the game runs at like 1 fps. Happens the most with Roblox and Superliminal. I usually have to reload those games several times before it works properly.

I don't recall if in task manager it shows it's using the gpu

Interesting, and also quite strange. What CPU do you have?

Uuh I think it's an i7 but I'm not at home rn so I can't check. I'll try to find the laptop online and see what the cpu is. If it helps task manager displays the integrated graphics as "intel hd graphics 620"

Online search was partly successful. It is either an i7-7500U, i5-8250U, i5-7200U. Iirc I think it's the i5-8250U
