AMD, Intel and Nvidia driver issues and last recommended version

Welcome!

In this thread you can check for issues with graphic drivers from AMD, Intel and Nvidia.
This thread is meant for use with madVR and its compatible players like Zoom Player, PotPlayer, KMPlayer, MPC-HC and my personal favourite MPC-BE.

I had to create an external file, because the first two posts are limited and had no more space for new driver releases.

But hey, maybe some Driver Dev may stumble over my thread here, please read this:

AMD
Known limitations of Radeon RX 5000 and 6000 GPUs (older generations are fine):
• Hardware deinterlacing is broken in every driver version -> It is poor quality when applied to
interlaced video and it is not adaptive anymore, which is a NO-GO for HTPC usage.
You can check this issue yourself: Download this short MBAFF sample file
The Hardware Deinterlacer should be aware that the characters above "WWW.D88.COM" are progressive and should not be deinterlaced, otherwise you will see flickering like in this picture
See here for more details
• Color levels (full 0-255 vs. limited 16-235) are broken. That means limited 16-235 which is the standard range for videos are interpreted as 0-255 and this leads to elevated blacks and dimm whites.
This issue can be best seen on displays which want full range 0-255, like TVs in PC Mode (PC mode for full 4:4:4/RGB support, so you do not use color subsampling like 4:2:2 or 4:2:0)
Also overriding the range for test purposes in MPC-BE (video tab -> Output range) does not take effect.
Dear AMD, if any of your driver programmers read this: Please fix this fundamental video bugs .These are there since RX 5000 series launch.

I just tried the Windows default app "Movies and TV" and this app does not support frame adaptive deinterlacer at all. So best is to download MPC-BE and play the sample file. Windows default app "Movies and TV" really sucks.

Sorry Micro$oft, but with all the skilled and well paid developers you can only achieve this? This is ridiculous.

Intel
iGPU Intel UHD 770 in 12 gen CPU is broken for MPC-BE in use with EVR and EVR custom presenter. You get audio but video is black.
To "solve" the issue is to rename MPC-BE to MPC-HC. Are you serious Intel? Do you really think that is the way of fixing bugs? That is ridiculous for the well paid developers of Intel!
See here for details:

Nvidia
I am really impressed of what you have done to fix all the HTPC issues of the last 3 years, but I think a little more tweaking of the 23.976 Hz (called 23 Hz, but not 24 Hz!) to get more than 10 hours of no framedrop/repeat like AMD would be nice. I know you can do that.
