Virtual reality pre-rendered frames Nvidia control panel question

[COWZYOV]

I just want to clarify, the higher this number is set to in Nvidia control panel, the less strain is put on my cpu?

Does this setting only affect VR, or is it for all games?

I wouldn't suggest you use it for VR, since more frames = more input lag = motion sickness for a lot of people.

If you hover the mouse cursor on the setting, then a short description should appear below,

there's also an explanation for typical user scenario's.

It seems this setting is only for VR games.

So I can’t use it to get an fps increase in non-vr games?

you wouldn't get an FPS increase anyways, it just makes it smoother and less tearing, just like any other kind of v-sync.

No, it won't change the strain on your CPU.
But it will allow your CPU to 'render' more information to send the GPU, while it is choked up.
It's one of the ways I improved my FPS on Battlefield 1, and if you're SERIOUSLY CPU bottlenecked, I would recommend using it, since it will increase performance.

Latency increase is negligible in my experience.
And more FPS (which is what this setting will do, if you're CPU bottlenecked), would result in higher framerates, which means lower latency.
They will cancel eachother out, or you will get lower input latency from the higher framerates.

This setting is for VR games only. HOWEVER, there is another setting for normal games, just called 'pre-rendered frames', it does the exact same thing, just for non-VR games.
If you're CPU bottlenecked, and have insanely low FPS, I do recommend setting it higher.

What're you talking about? This has nothing to do with any type of framesync...
This setting increases the buffer size of how much data the CPU can store about frames, before it's sent to the GPU, which in a CPU bottlenecked enviroment would increase the framerates.
It does make it smoother, because of the higher framerates, but it wouldn't change tearing, since tearing isn't created on the GPU, it's created by a frame overwriting another one in the front buffer.
