EDIT

The problem is finally fixed with driver 546.17, so kodus to nvidia for their work, BUT, there's still 1 game with issues, RDR 2

Screenshot_20231211_021600.jpg

According to many user feedback, RDR 2 has stuttering issues using external monitor (Hdmi) on both modes dx 12 and vulkan, internal screen no problems

Theres way to workaround this issue with dx12 mode only, nvidia introduced a new compability flag in the driver that fix CP 2077 and SF Stutters, if you add that specific flag to RDR 2 profile, it fixes the issue on Dx12 mode

But doesn't work on vulkan mode, external monitor, vulkan mode will stutter, with rebar off, compability flag added, etc, nothing can be done

This is the flag I'm talking about

---------------

Rtx 4000, ultimate mode + rebar on = stutters still present, nvidia still didnt fix anything

Btw, i have tried dozens of older drivers and NONE fix the stutter issue with CP 2077

Vídeo of the massive stutter

As long as rebar is ON in the nvidia driver + the game + ultimate mode = it will stutter like the video in 1st post

I will try more REBAR supported games in the next weeks, there are 22 titles with rebar, and i bet ALL of them will stutter...

P.S

There are reports of this stutter problem with rebar + ultimate mode , since June 2023 

4 months no fix in sight

P.S

I advice everyone to refund their laptops

Ask for the money back if they can't fix it

Thanks for the reply. Glad to know Asus is looking into the situation too, let's see what happens in the next weeks/months 

The new Nvidia driver 546.17 only fixes the stuttering on Starfield and Cyberpunk - 2 games

It seems the other 20 titles with rebar support will still stutter

Plenty of users confirmed RDR 2 is still stuttering, so i guess is not the only one probably 

 Can you provide info/links on other reports, please? This would help escalate. Although, naturally, it appears the issue is still driver-related pertaining to when REBAR is enabled.

13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090

Is not surprising, the release notes of 546.17 only mention the fix is for 2 games Starfield and CP2077

So all other 20 titles with rebar will continue to stutter...

Ok, regarding the Rebar situation, the problem is fixed, we didn't test all the Rebar games avaliable yet, but we tested many of them, and all are running fine since nvidia introduced the driver to fix CP2077 and SF stutter, I tested many rebar games using the last nvidia driver (for avatar), and everything is fine... 

BUT...
