"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.

I found another program that could be helpful, called Nvidia Inspector. In this program, you can select a game and it will automatically set the optimal settings for it. Another important point is the "Rbar" setting, which is enabled in GPUZ. However, I'm not sure if this is a display error. I also enabled the option in Nvidia Inspector and I feel like everything is running smoother.

Sure NPI is a well known program (I personally use everyday trying to squeeze the best smoothness from every game, even using undocumented features... some of my guides on Steam fixed a few games thanks to NPI, like Hotshot Racing - Frame pacing fix ). I used it also to fix the best I can Doom 3 and MAME to reduce stuttering on this G834JY (which is a nonsense and those applications should be a joke for it)...

rBAR is not always recommended though, and only a few games can benefit from it. There are also some games having problems instead like Red Dead Redemption 2, for which NVidia created a specific undocumented setting to fix stuttering caused by rBAR with this game: for DirectX is 0x00e942fe, for VK games is 0x20feaf0d (you have to enable hidden unknown settings clicking on the gear button in the toolbar of NPI...)

However wanted to point out that I don't see much problems with recent or demanding titles on my G834JY. Instead I'm disappointed by some old games running much worse now... sigh... that I'm slowly examining and trying to "patch" as I can through NPI itself and other few tools (but some still stutter and wasn't able to "fix")....

👉🏻 At this point, after reading a lot on the Internet including other user experience with equivalent Lenovo or MSI new laptops, I am convinced that it is most likely an NVidia driver problem with 4080-90 mobile GPUs in general! Let's hope for fixes in the near future, but in the meanwhile let's mailbomb NVidia with survey reports of stuttering with games (I already issued at least 4  bug-reports!): Submit driver feedback directly to NVIDIA: Link Here

I'm collecting more confirms on this other G834JY specific thread I opened some weeks ago: SCAR 18 G834JY oddities and issues including stutt... - Republic of Gamers Forum - 1019880 (asus.com...
... like this one (read also the video comments!): (9) RTX 4000 series on Mobile, stuttering, do not buy until fixed (if it ever will be fixed) - YouTu...

There's something strange with these ASUS laptops...
At 8:29 Hogwarts shows very bad frame pacing and 1% lows on the SCAR 18 compared to the TITAN 18:
