How to fix micro stuttering in games with RTX 4090 and i9 14900k? (I will go nuts)

Hi everyone,
I've been experiencing micro-stuttering similar to what's shown in the video, especially during scene changes. I'm seeing frame time spikes and FPS drops to 5 or 10.

Look closely at 8. second.

I've been trying to fix this issue for three weeks now and have tried everything I could find on the internet, but nothing has worked.

Here's my rig:
- Intel® Core™ i9-14900K
- ASUS ROG MAXIMUS Z790 DARK HERO
- GSKILL 64GB (2x32GB) Trident Z5 RGB 6400MHz CL32 DDR5 1.4V
- Corsair iCUE H150i Elite 360mm AIO
- Asus ROG Strix GeForce RTX 4090 OC Edition 24GB GDDR6X
- MSI PSU MEG AI1300P PCIE5 1300W 80+ PLATINUM
- 10 x Corsair iCUE AF120 RGB Elite 120 mm PWM case fan. 4 exhaust, 6 intake
- Windows 11 Pro  ( up to date)
- Samsung 990 Pro Nvme 4TB

Here's what I've tried so far:
- Updated to the latest BIOS & VBIOS with clearing CMOS.
- Installed the latest NVIDIA drivers.
- Updated all drivers from the motherboard manufacturer's website.
- Tried with XMP on and off.
- Tried with GSYNC and VSYNC on and off.
- Tried different motherboards and RAM.
- Ensured that the PSU and all cables are securely connected.
- Ensured that GPU, CPU, and RAM were fully inserted.
- Using balanced/high-performance power plan.
- Ran Memtest, AIDA64, and Karhu RAM test for at least 8 hours, all came back okay.
- Tried with hardware-accelerated GPU scheduling on and off.
- Tried with HDR on and off.
- Reinstalled Windows 11 three times.
- Installed games on an NVMe SSD (Samsung 990 pro 4TB).
- Reinstalled NVIDIA drivers using DDU seven or eight times.
- Reapplied thermal paste four times.
- Tried ASUS multicore enhancement with both enforcing all limits and auto settings.
- Installed contact frame.
- Tried 2 different HDMI 2.1 cables, multiple HDMI ports (both GPU and monitor), 2 different display port cables, and different display ports on the GPU.
- Changed the monitor with a brand new one.
- Set Nvidia control panel to maximum performance.
- No Armoury Crate, iCUE, etc. bloatware. Pure clean Windows. Only fan control and SignalRGB installed. No background processes while gaming.

Games experiencing micro-stuttering:
- Cyberpunk 2077
- Battlefield 2042
- Microsoft Flight Simulator

Games running smoothly:
- CS:GO
- Call of Duty: Warzone

Please help me and guide me to the right path for debugging more.

Hi @mrblithe ,

based on your issue, since you have tried many methods and the problem still persists, we suggest trying different hardware platforms or replacing the graphics card to test different games to eliminate the possibility of hardware failure.

Considering that you can run CS:GO and Call of Duty: Warzone without issues, we also recommend contacting the developers of the games for further assistance.

If testing other games with a different graphics card runs smoothly without any lag issues, we suggest taking the graphics card to the nearest official repair center where engineers can diagnose the problem for you. 

Thank you.

Hello

Did you manage to solve the problem?
I experienced similar problems when I used MSI Afterburner for UV GPU, I uninstalled everything from MSI and it's ok, also the RGB backlight is a problem when any effect other than static light is turned on.

Try running UFO Test: https://www.testufo.com/animation-time-graph to see if there are any deviations.

I have a similar set:
CPU: Intel i9 14900k (Adaptive offset -0,075v)
MOBO: Asus ROG Strix Z790-E Gaming Wifi II
RAM: G.Skill Trident Z5 RGB 7200MHz CL34-45-45-115 1.40V
GPU: Asus ROG Strix GeForce RTX 4090 OC
