99% fps?

[bRice153]

I am using the nvidia overlay to monitor my fps in this game. I have a cap of 140fps set and in the overlay it shows 140fps but what is confusing me is the "99% fps metric" below it.

Those numbers jump all over the place and will go from 80 to 40 to 100. What does that metric even mean?

I always thought all that mattered was fps but never understood what the 99% fps is.

It seems the fps and 99% fps never match and the 99% one is always way lower than the fps metric.

Its supposed to be that way. E.g if your cpu is bottlenecking you the % utilization of the gpu will drop. If its 99-100% your gpu is working its max and your cpu is probably "relaxing". Nothing to worry about.

If your cpu is very slow and your GPU is a beast the GPU wont be able to generate as much frames as it potentially could. Same thing other way around.

Well in my case it's a 5800x3D and a 4090

I believe this is what you're looking for:

"Uses rendered FPS scheduling metrics to show 99th percentile data
1 frame out of 100 is slower than this frame rate. 99% of the frames will achieve at least
this frame rate."

That's confusing. So which is the true accurate fps? The one that says FPS or 99% FPS?

its not confusing, your fps is the X fps, the other is your gpu usage towards fps, its not a measure of how much fps you are getting but a measure of how much you're gpu is being used toward fps

That makes no sense as there is a GPU usage stat. The 99% fps is an independent stat. Not Usage, not latency, not fps

I know this is an ancient thread, but just incase anyone else comes across this in a search, most of these replies are completely wrong.

Irongrill was correct, it's not GPU usage it's the 99th percentile. That measurement is showing the bottom end of your frame rate, so it will always be lower than your FPS reading. Often significantly so.
