Does capping FPS helps or stresses cpu?

[Tom is a Door]

At the moment my pc is pretty unbalanced, I hope to change it soon, but for now I have to deal with A4 6300 as my CPU and an awesome R9 270 as my GPU, was wondering if capping would give some breathing space for the cpu if I capped it 30 if the games allows me

doubt it, could try it though.

Why cap it?

It's not like the GPU is being mean to the CPU and stressing it in any way. The GPU depends on what the CPU is doing, the CPU will do the compute part of the game, and pass instructions on to the GPU, which then proceeds to render them.

See it like the CPU takes the load, and the GPU gets its part to do on the game. The GPU is way faster, in this case, and it gets the job done easily, then it gets bored until the CPU finishes what it has to do.

With frame capping you are only telling the GPU to do even less. Either at 20fps or 120fps the CPU has to handle the same amount of data to the GPU, you aren't helping it by crippling the experience.

It would probably cut down on heat if there are thermal concerns.

wont change the absolute performance at all. You might get a smoother gameplay if the framerate remains at 30 than if it's jumping between 40 and 30.

But you won't speed up the PC at all.

 

And yes, you draw less power.
