Output frames does not match actual frames

[robotamski]

Hello,

I have had a bizarre PC issue for multiple months now, and I have had enough. As the title states, my PC is more than capable of outputting the right amount of FPS for my monitor's Hz; however, now and then it just decides to show a high FPS in-game, but output somewhere around (what feels like) 120Hz. I've built multiple PC's throughout my years and have never seen this issue before.

 

PC Specs:

• RTX 4070
• AMD Ryzen 7 9800x3D
• 32Gb 6000Mhz RAM (slots 2 and 4 (yes, it is correct according to my motherboard))
• 1000W Seasonic
• 360Hz Asus Oled

I've triple-checked the temperatures and cable connectors; everything looks as it should, so I am really confused as to what could cause the issue. It is, as I stated before, not consistent since one day games run perfectly fine, and another day it displays (let's say 700 FPS in Valorant), but feels like 120.

Does anyone have any idea what I can do?

 

I appreciate all the help I can get!

 

Regards,

Ok, take a step back here and look at this from our perspective. You've got a problem that can be quantified using basic tools to give you hard numbers (framerate) yet nothing is mentioned here. We're completely in the dark with no data to go off of, just "feelings" that things aren't right. 

 

Two things are at play here and they are independent. 

 

• Display refresh rate
• Game render/frame rate

Display refresh you set in windows/NVApp and you're done. Game framerate is how quickly your GPU is able to render frames given many factors such as the speed of the card, the resolution and the games settings.

 

It seems in a bit of a roundabout way you're simply describing that the framerate is lower than you expect. You didn't mention a resolution but context clues tell me if its OLED and 360Hz, its 1440p. Just having a 4070 doesn't mean you're going to be able to achieve 360fps or thereabouts in every game. In fact i'm sure in many AAA titles you won't get anything near that natively, but thats when settings come in to play like DLSS/Framegen. 

 

So, my first suggestion is simply to get idea of what it is. You have an Nvidia card so the simplest method would be to use Alt-R and take advantage of the overlay that's part of the Nvidia app. (can be configured with Alt-Z). If you can't figure that out. Nvidia Frameview is dead simple, as is Intel PresentMon. Then there is identifying why the framerate is lower than expected. Are you simply reaching the performance a 4070 can achieve in that game at that particular point? 

 

Many variables.

Thanks for the reply. The FPS itself is not the issue, as both NVIDIA's Alt + R and the shown framerate by the tool in-game show steady and high FPS. The GPU itself is not a particularly powerful one, so, as you mentioned, multiple AAA games are not able to run the games to my monitor's desired refresh rate. I mainly spend my time on competitive shooters, which, for the most part, are quite CPU-bound, so the given FPS normally rests between 400 and 900, with exceptions ofc. 

 

It is a 1440p monitor. I apologize for not mentioning it. Completely forgot, however, it is set to 360Hz both in-game and through Windows/ NV control panel. As far as I'm aware, the 1% lows are completely fine as well, as far as my testing has seen, which is also supported by the fact that I am not having any sudden stutters, but rather a constant feeling of low framerate. 

 

It's hard to put concrete data into account here, as I have yet to see any irregularities other than a complete feeling. This might be very discrete, which I do apologize for, but after a couple of 10's of thousands of hours in First-Person shooters, my feel for irregularities in framerate has been... heightened. 

 

Do you have tips on tests/ checks I should do outside of the regulars (Temps, In-game FPS, Monitors HZ, and the build itself)?

 

Thanks again!
