another bonus info that might be relevant.

i am running two screens.

Samsung 240 hz 1440p

AOC 144 gz 1080p

i have issues with connecting 2 x dp to gpu and the screens, if i want my mainscreen to have 240 hz refresh rate.

read that it might be the issue. ill try now with just 1 setting for both 144 hz.

might fix it

okay tried multiple things now.

and still does not work

but CS2 eg, i have no framdrops. - only apex + fortnite - even i loading menus its visible.

i have a log from hardware monitor, as a csv file. - is it possible to share?

Using 2 monitors has known issues such as, some gpu configurations might force the high-refresh-rate monitor to sync with the slower one

It's often best to use monitors for separate tasks (like gaming on the high-refresh-rate monitor and browsing on the low-refresh-rate one)





IMO this sounds like unstable RAM to me. Or maybe insuffient page cache (Windows virtual memory) so, try to increase
Windows 11's page cache by manually adjusting the paging file size (How to):

Advanced System Settings, navigate to the Virtual Memory section under the Advanced tab in Performance Options, uncheck "Automatically manage paging file size for all drives," select a drive, choose "Custom size," and then enter your desired initial and maximum sizes in megabytes before clicking "Set" and restarting your PC

IF everything else is not doing it for u, I hv written these for u and I hv no more ideas on it and good luck!

Step 1 – Uncap GPU VRAM Allocation (Registry Fix)
Open regedit and go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
Create / edit these DWORD (32-bit) values:
"TdrDelay"=10
"HwSchMode"=2
"DisablePreemption"=1
**To Undo/Revert = delete or set to 0
Restart PC after changes for smoother VRAM allocation and fewer driver resets.

Step 2 – Disable Windows VRAM Compression (Latency Fix)
Run Command Prompt as Admin and type:
reg add "HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" /v DisableGpuMemoryCompression /t REG_DWORD /d 1 /f
Revert:
reg add "HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers" /v DisableGpuMemoryCompression /t REG_DWORD /d 0 /f
Restart PC to apply.
Removes extra compression overhead → smoother frame pacing & faster texture loads.

Step 3 – Tune NVIDIA Profile Inspector + Control Panel
In NVIDIA Profile Inspector, set:
Frame Rate Limiter Mode → Off
Low Latency Mode → Ultra
Power Management Mode → Prefer Maximum Performance
Shader Cache → On
Texture Filtering Quality → High Performance
CUDA – Force P2 State → Off
Memory Transfer Rate Limit → 0
Then, in NVIDIA Control Panel → Manage 3D Settings:
Texture Filtering – Trilinear Optimization → On
Threaded Optimization → Auto
Vertical Sync → Off
Apply changes → more stable clocks and memory usage.

Step 4 – Optimize System Paging + Shared Memory
Press Win + R → sysdm.cpl → Advanced → Performance → Settings → Advanced → Virtual Memory.
Uncheck Automatic management and set:
Initial size = your RAM (in MB)
Maximum size = 1.5 × RAM (in MB)
Then run (Admin CMD):
wmic computersystem set AutomaticManagedPagefile=False
**To Undo/Revert Virtual Memory settings to “Automatic.”
Keeps texture streaming smooth when VRAM is maxed out.

Step 5 – Flush VRAM & Shader Caches Safely
Run these (Admin CMD):
del /s /q "%LocalAppData%\NVIDIA\DXCache"
del /s /q "%LocalAppData%\NVIDIA\GLCache"
del /s /q "%LocalAppData%\D3DSCache"
del /s /q "%AppData%\Vulkan\Cache"
ipconfig /flushdns
Restart PC. Caches rebuild automatically for cleaner frame loads and faster texture streaming.

okay.

i have tried to clear cashe now.

tested all hardware.

i even had it in a pc repair shop and they couldnt find the problem.
