You're facing challenges with timing issues and frame spikes, and you're running low on creative solutions.
You're facing challenges with timing issues and frame spikes, and you're running low on creative solutions.
So here we are... let's look at the details:
Processor: I9 9900k
Graphics: Asus RTX 2080ti
Motherboard: Asus z390-F
Memory: 4x8 Corsair 3200mhz
Power Supply: EVGA 750 G2 (eco mode active)
Operating System: Windows 10 64-bit
GPU & CPU idle temps: 38-40°C
Cooler: NZXT Kraken x73
Storage: Two M.2 drives – one for Windows and related apps, another solely for games
Using afterburner; frame limits from RTSS. Slight GPU overclock detected, but problems persist even when turned off. No CPU overclocking.
My concern is these precise timing spikes—either increasing or decreasing—which show up in RTSS stats and are visible on the screen. They disrupt smooth gameplay and cause noticeable jitter every second, which is what’s bothering me.
Even with my setup, I can force a game to run at 60fps, and in RTSS, at lowest settings, the issue still occurs, despite my hardware being capable of much higher performance.
I’ve tried everything possible. There’s no visible thermal throttling. At full GPU load, temperatures stay between 60-70°C, and CPU usage never exceeds 50%.
I’ve attached some screens to illustrate this problem (images available here):

Have you considered enabling Vsync on high or even ultra speed? Also, check if hardware scheduling is available—it’s a newer option. This issue seems to stem from timing mismatches between the GPU and your monitor. Do you have another display ready to test, like a TV or something else?
You’ve explored several options—try listing what you’ve attempted so far instead of repeating them. A good next step could be uninstalling the existing drivers via the display driver uninstaller, updating to the newest version, and checking for a BIOS upgrade.
I’ve been struggling a lot, making it tough to recall. To make things easier, I performed a fresh installation of the Nvidia drivers and used a display driver cleaner in safe mode. I also checked my BIOS settings, which are up to date.
After that, I tried Kombustor, but the problem persisted.
I’m open to trying any solution right now.

Have you attempted this with Afterburner and RTSS removed? Also, did you try turning off the motherboard’s HPET timer—Windows should handle it independently.

The display is a Samsung CRG9 32:9 at 120hz, and I attempted my older 144hz monitor—it produced the same problem. I tried enabling Vsync with all settings, but the issue remains. Since I didn’t have hardware scheduling options, I forced an update to Windows and now have the correct configuration. It changed things somewhat; I believe it’s improved a little. I’ll need to keep testing to confirm. I’m starting to notice that the timing between the system and the app feels increasingly off.
It looks like your motherboard doesn’t have a switch for that (Asus Z390-F gaming). Maybe you’re onto something. I checked WinTimerTester and it displays a fixed 10MHz query performance rate.
When I looked up HPET commands, they don’t seem to work—bcdedit /set disabledynamictick yes and bcdedit /set useplatformclock true both returned no changes.
Hardware scheduling seems to have made a big difference, though I’m not sure if it solved the issue entirely. Does that make sense?
You're restricting your frame rate to 60 on larger screens because it helps ensure smooth performance. To achieve this, you should also lower your monitor's refresh rate to 60MHz for better synchronization. The timing setting can impact certain games, but it only affects a limited number of titles. I believe the timing issue isn't related to your problem at all.
Hello
I made sure to keep it under 60 to check if the problem appeared at lower frame rates as well, not just when reaching the maximum FPS.
The ideal setting for my monitor is 100Hz — since it only supports a full 10-bit color range with HDR1000.
If I switch it to 120Hz, I have to use an 8-bit color mode.
To control this, I’m using RTSS to cap the frame rate at 97fps while keeping the monitor at 100Hz.
