they all have time bombs.

Can someone explain what is the issue with HAGS and how to reproduce it? I never disabled it, but I don't see any issue with it.

Me neither, I don't think it affects all users.

the reported frame rate and composition rate changes after roughly 10-30 mins of playback.

i'm not affected it is usually reported with 23p mode which i do not use i use 119p.

It has been mentionned here by... myself, but also in this thread.
Except that I had it with a Radeon card, not nVidia, and madshi reported it to nVidia and not AMD (from what I read). And I noticed it only in 23p mode, because 90% of what I watch is 23,976 Hz so I use 23,976 Hz only.

Finally got around to opening up the NUC to replace the fan and thermal compounds. One thing that surprised me, there was a thick dust mat between the blower and the heatsink fins, effectively shutting off airflow. No wonder. It wasn't visible from the outside.

Now that everything's replaced, instead of bouncing off 105C, turning on a bunch of the stronger algorithms only put it up to 75C.. that's a 30C degree difference in temperatures under load, wow and that's with the fan at 3800rpm instead of 8000+. Usually around 3300rpm now.

I can't get HDR mode to enable when I play a hdr file on my LG CX (connected to PC via HDMI from RTX 5090 FE). Latest madvr version. Windows 11 LTSC. The video is displayed with SDR tonemapped colors. The TV doesn't switch to HDR mode.

I've set the hdr mode to 'pass through hdr to display' and 'send hdr metadata' on.

I kind of had that issue on my Windows 10 22H2 system with my 3060 outputting 4k120 RGB HDR over HDMI to my Samsung S90D

Firstly directX 9 doesn't support HDR at all so you will need to use DX11 in madvr settings

Secondly i was having an issue where even in Dx11 mode it would randomly not switch to HDR when in windowed mode but would reliably switch when going fullscreen exclusive, so try full screen exclusive

Lastly right click the media player executable and "disable fullscreen optimisations"

But there is some issue with madvr not setting HDR mode in quite the orthodox way or something like that, try asking AI to give more details there could be something else i forgot

yes ask the ai...

madVR tries to use the AMD and nvidia HDR api. and there is nothing wrong with that. a very old one in the AMD case amd_ags_x64.dll from 23 03 2017 5.0.6.0.

the alternative is to change the windows from SDR to HDR which Microsoft doesn't want you to do. so do it as mircosoft wants you to do it manual.
