I haven't tried GExperience yet...well tried it many years ago once and was confused about a few things around it. Can you share a screenshot of your vanguard for comparison?

25 Pages of a driver discussion, i see

New driver next week, probably.
In fact, totally useless! Next GRD will come up today or friday for Dying Light 2 launch

Tried 2.25x in the end and although it did counter some of the grass shimmer/beaten path gravel shimmer the drawbacks are too great. Still, interesting experiment.

Awh. I just noticed madVR no longer gets 10 bit mode in windowed fullscreen mode. May be this is what solved my stuttering issue. But in that case, it was a bad move from nVidia. I want working, stutter-free 10 bit movie playback with madVR!

For some reason, madVR is limited to 8 bit on my system since I updated to this driver (I tried to set the display properties to 10 bit to no avail and madVR reports the display mode is 12 bit). But it's still better than the stuttering I got with the previous few drivers.

I'm having the same issue. With 511.23 I am not getting 10bit video passed to madVR then to the display regardless of any other settings. It was working fine with 497.29, I've never experience the stuttering you mention on any driver version, so I'm back on 497.29 and getting 10bpc working correctly.

Windows 11 22000.438 (x64) , nVidia 511.23 , madVR 0.92.17 (x64), MPC-HC 1.9.18 (x64)
Gigabyte RTX 3080 (10Gb) WaterForce WB (RBar BIOS) + LG 55C9 (05.20.07) on HDMI 2.1 port + Denon AVR 2809 (with a DVI monitor hooked to it's HDMI 1.3 output via passive adapter) on an HDMI 2.0 VGA port
Display output mode set to 12 bit RGB (Full range) in NVCP for the LG C9, left at default (8bit Full RGB) for the AVR+monitor.
The Windows desktop is normally in 2160p120 SDR with G-Sync (full+windowed) but madVR auto-switches to 2160p24 for movie playback (where G-Sync disengages because 24 is outside of the 40-120 range).
When maVR goes into fullscreen mode (actually borderless windowed because exclusive fullscreen is not enabled for madVR since it's no longer available in modern Window) the diagnostic OSD (CTRL+J) queries the display mode as 2160p24 12 bit Full RGB (and also NVAPI HDR mode where applicable) but it's output mode remains 8 bit (both for SDR and HDR10).
The expected behavior is madVR's output being 10 bit (both for 8 and 10 bit videos) and a stutter-free playback.
With the last few previous drivers (and one Win11 patch before the current), 511.xx the output was correctly 10 bit but the playback stuttered. This stuttering stopped when I brought on the seek-bar and thus madVR dropped out of fullscreen mode and switched back to 8 bit output mode (stuttering returned when the seek-bar disappeared and madVR switched back to 10 bit mode).
With even older drivers (and also some Win10 patches before the current one), pre-49x.xx everything was fine (correctly 10 bit output without any stuttering).
This also affects 2160p25 (UK content), not just 2160p24 (US content), both H264 SDR FHD and H265 UHD HDR10 formats.
I didn't try to downgrade to significantly older (pre-49x.xx) drivers and didn't try to uninstall Win11 updates. But everything was fine a few months ago and I had no hardware changes (not even UEFI Setup or VGA card OC changes).
The video decoder is set to DXVA11 (native). Audio is decoded on the CPU and sent out as LPCM 7.1 24/96 (no Atmos) to the HDMI 1.3 AVR.


The bold bit above is referring to the fact that fullscreen exclusive mode (in MadVR render settings) isn't proper fullscreen because of windows fullscreen optimizations forcing it to borderless windowed correct? Just disable windows fullscreeen optimizations for MPC's executable, then you will get proper exclusive fullscreen.

I have an almost identical setup to you (minor differences: Win10 21H1, 3080Ti, LG CX, Denon AVR 1910,10bpc RGB fullrange set in NVCP). However I do not let MadVR auto-switch the display mode, the CX stays in 2160p120 SDR GSYNC-ON, this is because I also use SVP frame interpolation to interpolate framerate up to 120fps regardless of source framerate. As I said above I've never had any video stuttering on any nvidia driver but 511.23 did break 10 bit output so I'm back on 497.29. All my content is H264/H265 SDR FHD.
