"If I enable HAGS, I get micro stutters

[Nirexis]

Good day,

First, to my system:

• Notebook: Asus Rog Strix Scar 16
• CPU: Intel Core i9 13980hx
• GPU: Geforce RTX 4080 Mobile
• RAM: Kingston Fury 32 gb 5600mhz Ram Module
• OS: Win 11

To my problem:

For months I have had problems with micro stutters, I have already tried everything possible:

• No Gsync / no Vsync
• Gsync / no Vsync
• Gsync + Vsync
• Each option with FPS Limit + without Limit
• FPS Limit in Nvidia driver, Ingame Engine or MSI Afterburner or Rivatuner.
• I have formatted the computer several times
• GeForce Experience installed / uninstalled
• Different power plan options
• Different graphics settings (from everything low to everything high)
• Different resolutions
• Game Mode on / off
• Fullscreen / Windowed / Borderless
• Current BIOS / older BIOS version
• Overlays of any apps On / Off
• The temperatures of my components are all within the normal range
• New RAM
• Other monitors with 240 hz
• All drivers for all components up to date / older drivers also tried
• Different mouse polling rate
• Different mouse
• Resizable Bar is automatically on, I don't think I can deactivate it anywhere either

Now after months I finally had the idea to deactivate HAGS (Hardware Accelerated GPU Scheduling) and I couldn't believe my eyes. Everything runs incredibly smooth and the micro stutters are gone.

The big problem now is that you have to have HAGS activated to activate Frame Generation... In some games, not even Dlss 2.0 works. Does anyone know the problem and could solve it? Games like Immortals of Avenuen are hardly playable without Dlss... Unfortunately, you also have to restart the PC when changing the HAGS setting, which would be extremely annoying... especially since more and more games with Dlss 3.0 are coming out.

Depend how often are this random spikes and also did you have other things that also have latency spice for this problem you can check in google wdf01000.sys i also haved a problem whit this but i forger how i fix it 

If you can try to fix this random spikes that will improve your system and read in google watch in youtube 

This is my graph

When i reset the program, it takes about 20 seconds for  the spike to appear. I have updated all drivers and also disabled them as a test without success. I has no effect.

Yes... unfortunately DPC Latency as of today with everything up-to-date still has huge spike and LatencyMon tool will fail the test... which per-se could explain bad micro-stuttering in some games/apps.

One user said he solved all problems switching from Intel VMD (BIOS) to normal AHCI NVMe mode (Windows will install generic NVMe Microsoft drivers).

Theoretically you can try: before you change BIOS settings though you have to uninstall VMD driver though (don't remove the driver, just uninstall) or Windows won't boot with BSOD:

... so the steps should be:

1. uninstall RST VMD driver (if you don't need RAID of course): Win will ask you to reboot to apply changes
2. prepare to reboot in Safe mode (should force Windows to install NVMe drivers). From CMD Admin enter: 

   bcdedit /set {current} safeboot minimal

3. at this point reboot and press F2 to access BIOS immediately, and disable VMD settings. Reboot
4. you will now boot in Safe mode (prepared at point 2). Disable Safe mode and just reboot: 

   bcdedit /deletevalue {current} safeboot

this should work.

Make a backup with Macrium Reflect or some other backup tool before you try, just to be safe.

Can you test that? I'm feeling a bit insecure about everything right now because I have exams coming up soon and I need all the files etc. Data backups often go wrong too

[eXplode]

if you have exams you can wait or if you have a USB flash drive make a system image restore point 

that will help even if you reistall the windows you can load the image restore point and everything will be restored to 100% 

my restore points are only image files

I'm getting sick of this laptop... It has so many stuttering issues with old games I never had on the old GL703GS with 1070 8GB. It should have been an improvement ONLY for me, not  a trade-off. 

In dGPU only, it runs well only with recent titles as far as I can see, but if you even try to play good old Doom 3 (I have it on Game Pass) it runs like 💩  not because of poor fps of course but for unbearable nonsense stuttering (try strafing left-right with keyboard and you'll notice many jumps/lags/hitches) , which is ridiculous for this and MANY other old titles... as well as UFO Test: Ghosting (testufo.com) running so bad with visible nonsense micro-stuttering while scrolling, not present when on iGPU in Advanced Optimus mode.

There's something seriously broken when running on NVidia GPU only! Is it a 4090 laptop general issue (also for MSI, Lenovo etc.)?

Don't know if it's related but I've noticed while running UFO Test: Ghosting (testufo.com) GPU Clock is ever changing between 420-590MHz and never gets stable....

EDIT:

To add to the nonsense: if you play Doom 3 in Advanced Optimus mode (yes, will still use dGPU, double-checked) things get better (???) but will still show some cyclical lags while strafing... Really weird. Everyhing runs perfectly fine and smoothly on GL703GS, old and new games, even though performance are not the same of course... but on G834JY it's a lottery especially if you're not a teenager playing only the most recent titles!

I give up... I've been looking for a solution for months, I've wasted hours trying to find a solution, without success. I'm going to sell the laptop. NEVER AGAIN ASUS.

[eXplode]

Bad ... I also haved a problems that take me weeks or months to solve and in the end for some things i didn't find a solution 

Good luck whit the sell and your new laptop 🙂

[hexaae]

Sigh that's crazy... But the question is: is it a ASUS laptop issue only? Lenovo, MSI.... with 4090 laptop GPUs have no stuttering issues?
