Windows 10: Windows 10 HDR lag and stutter

/u/liadanaf · Feb 12, 2020

I got a samsung qled 70r - when i turn on windows 10's HDR, videos i stream on youtube and netflix app stutter and lag... I tried lowering 60hz to 30hz and 24hz and playing with every combo of RGB and chroma but nothing works

However, if i turn HDR off and use madvr's with mkv HDR movies I can play them just fine even on 60hz....

What am I missing?

Windows 10 Stuttering/Lagging with Graphical Glitches

These are the LatencyMon stats once the problem sets in

The problem didn't come in Safe Mode - although I only used it in Safe Mode for about 10 minutes.

*I usually only needed to input a PIN password to log into Windows. After booting into Safe Mode it started asking for my password (i.e. Microsoft Account password). It hasn't asked for the PIN since then. Is this normal? Maybe some kind of protection enabled by Windows itself?

This is the LatencyMon stat without the problem:

As you can see it says that my system has no latency issues.
Something weird I noticed is the difference in Measured and Reported CPU speeds - 1 Mhz and 3293 Mhz. How is that possible? I mean will the system even boot up if that's the actual speed?
There is also and Indepth Latency Test shortcut created by the program. Do I need to run it as well?

HDR Washed out on Windows 10

I believe I've finally found something that works for HDR on Windows 10.

When on the desktop and in games that do not have an in-game option to activate HDR, got to Nvidia Control Panel then to Change Resolution.

After that, scroll to the bottom to option 3 and select Use Nvidia color settings. It should be set 32-bit RGB 8bpc Limited by default. Simply change the Output dynamic range from Limited to Full.

I definitely noticed a color change after doing this despite the TV not saying HDR in Info section.

Only do this for desktop or games that do not have an ingame option to activate HDR. If you do, it will look overly bright.

Also, make sure you have HDR on on your TV. In my case it was in Settings - General - External Device Manager - HDMI UHD Color then just select whichever input you have the PC plugged into.

My TV model is a Samsung UN40MU6300 and am now running on the latest Windows 10 build (1803), hope this helps someone!

That was suggested in post number 3 I thought?

Windows 10 Stuttering/Lagging with Graphical Glitches

I have installed Win 10 Pro and been using it for a while. I also have a ASUS STRIX GTX 960 OC with 2GB GDDR5 video memory, and 4GB ram. Lately I have been noticing a lag/stuttering after using the computer for a while. Mind that the problem doesn't come on as soon as the PC boots up (the boot up is quite fast). Instead it starts after an hour or so into the usage. The lagging/stuttering initially starts off as some graphical artefact (the text inside a window of an app starts refreshing - it basically vanishes and then comes back on). The problem is only limited to windows of the apps and Explorer itself. After a while the system starts lagging a lot. The stuttering and graphical anomalies appear periodically and the lag is also in sync with this period.

This is the lag at the most extreme

An interesting thing that happened is that while I opened the Nvidia Control Panel to take a gif recording, the graphical stuttering immediately stopped. The lag however was still there, but very minute. This leads me to wonder whether the glitch/bug is caused due to a bad Nvidia driver.
The driver in question is 361.75
I know that the driver is problematic but I also read that the newer version 364.51 is also having a lot of problems.
This is the Task Manager after I opened and closed Nvidia Control Panel

However, after the problem still came back (in about 10-15 minutes), I tried the same method - opening and closing Control Panel. This time, the problem still persisted. So maybe something else caused the stuttering to go away. I am not sure of the chain of events that precisely led to this so I couldn't recreate it.

This PC is usually very fast, can run most games on ultra-high settings (albeit at my display resolution of 1366x768) and basically runs without a hitch. However, once this sets in, after a while its annoying enough that I restart it. Then the cycle continues.

I am pretty sure that the problem is software related (maybe bad Nvidia drivers?). The graphics card is pretty new (Nov 2015) so I can basically rule out any graphics card problem. The problem however does show up in COD MW 1 (Multiplayer). The entire screen flashes in sync with the same problem. Basically, if I'm playing the game once this flashing of windows starts, the entire screen goes black and comes back on - there is no lag, just the blacking out - completely in sync with the window flashing. The screen refreshing problem exists ONLY with this game, all others run without any problems

Any help? I am ready to roll back to previous graphics drivers but a clean Windows install is a no-no. I have way too much data to backup
