Question Average FPS is high but single digit 1% and 0.1% lows

[stutterdeath2025]

I experience a lot of microstutters in almost all games (except tf2 probably), and my 1% and 0.1% lows are atrocious - they are around 3-1 fps, meanwhile average fps is 130. I only recorded them in one game (dead space remake), but stutters appear in every game, so I think this is happening in other games as well.

I recently upgraded my pc and replaced everything except discs, keyboard and the monitor (monitor is ~ 3 months old), but the issue still persists. Current specs:

CPU Ryzen 7 7700, GPU RTX 5070, PSU DEEPCOOL GamerStorm PN850M, MB 650M Gaming plus wifi, RAM 16x2 ADATA XPG Lancer Blade, Samsung SSD 970 PRO 512 GB, 2 x 4 tb Toshiba HDDs, LG Ultragear monitor​

What I tried:

• Changing power plan
• Disabling monitor audio (nvidia high definition audio)
• enabling A-XMP
• Using DDU and reinstalling drivers
• Several windows reinstalls
• Deleting Nvidia app
• Locking framerate + vsync + gsync
• Disabling game mode and game bar
• scf scannow command
• installing games on ssd instead of hdds
• checking disks health (all 100%)
• Disconnecting LAN cable
• Disconnecting the keyboard or the mouse. The latteer seemed (only seemed though) to help the issue (the mouse is old), but I am not sure yet, will need to test with a different mouse
• Problems started before I installed msi afterburner, so it cant be the issue as well
• the GPU is powered via 12v 2x6 connector, so that cant be the issue
• I use Display port

Maybe the BUS usage is some kind of a lead? It seems to be frequently hitting 100%, but when I googled this I couldnt find any information on whether this could cause problems or how to fix it.

Hey there,

What bios are you running on the mobo?

Hi, I am using the base one, which was running when I unstalled the motherboard. I didnt think it could be the issue, but I am going to try and update it, then report back

Yes, this could very well be the issue. Some of the newer bios updates solve GPU bugs. Make sure to clear CMOS after the bios update.

Okay, so I did three things: replaced the mouse and then tested the game, then updated the bios and tested it again, and then changed the mouse back to the original. At first It felt like replacing the mouse improved things a bit (1% and 0.1% lows increased):

Then I updated the bios, and I dont think it changed anything

After doing that I returned the previous mouse, and framerate was the same (didnt save the logs sadly)

So I am very confused- it seems none of these steps in particular helped, so most likely the changes have to do with the way I played the game, idk. My fps is still very chaotic and 0.1% lows are way lower than they should be at 1080p high settings

If you are using the latest Nvidia drivers, go back one version. Many people said they had issues with them.

I doubt thats the issue, since I had stutters even on my previous gpu (3060). if Nvidia drivers caused this, I would need to go back in 3-4 months of drivers (when the issue started to be noticable), and there were no drivers for 5070 at that time

 

[stutterdeath2025]

I looked into the issue a bit more. Stutters seem to happen each 30-40 seconds, but sometimes more frequently. Cant really say anything else.

Get an app called Zen Timings, run it and check the FCLK value, rightmost column second line.

Find the setting for FCLK in the BIOS (i don't know what its called in your board you may have to look it up, its the infinity fabric speed) and try manually setting it to 1800 which is the default speed

Nothing changed. I also tried increasing the frequency, but that caused black screen, so I had to clear cmos. Also, Idk if this will help, but in one of my cpu-intensive games (rts) my screen starts to flicker (losing brightness) when I hover over a lot of units. This doesnt happen in other games (including other rts), but it didnt happen before the upgrade. Maybe its something with the cpu? Like, it should be responsible for 0.1% lows. It's temperatures seem to be good and stable

Here is the picture with 1800 FCLK. I feel like stutters are the same or worse

GPUZ if needed

Now that i look at the charts a bit more closely, the big spikes and dips are in the GPU2 which should be the iGPU of the 7700. Did you connect the screen to the 5070 or the motherboard slot?

The GPU slot. Its just that for some reason main gpu is labeled as GPU2, and amd gpu (probably MB integrated) is labeled as GPU1

Before upgrading, the previous system worked?
If you still have it, try putting the new GPU in that and see if it works and the old GPU in the new system to see what happens. At least this way you can exclude the GPU as the problem

 

[stutterdeath2025]

Here is me playing cpu intensive game (Hoi4). Two things of note - frametime is stabely very high, and cpu usage is strangely low. Doesnt make sense to me

okay, gonna try it now

So, fps became way more incosistent (as expected), and micro stutters appeared more often.

 

[Teknoman2]

My only guess is that the PCIe slot may be bad if you get the same thing with both GPUs.

Should I try installing gpu in the second slot then?

 

[stutterdeath2025]

tried running it in idle, there is gotta be something loading cpu. aaaah

Maybe I have to somehow make my gpu as GPU1, and my integrated gpu as GPU2?
