Good to know I'm not the only one who has this problem. I wonder if Madshi must change MadVr in some way, or if it is a Win10 1803 bug.

For fun, I tried a few things. I installled the Windows 10 1803 Spring Update on another older computer, different processor brand (Intel) and different Nvidia card and the same issue with the madVR happened on that system. For more fun, I rolled back my main rig to the previous Windows 10 build and MadVR worked as it did before the update. So, for me and my system, Windows 10 1803 is the culprit. I have reinstalled Windows 10 1803 on my main rig again, and the problem came back. I'm sticking with it for now as I've seen performance increases with games and I want to mess around a bit with the new features. ** More info I can provide, after further testing is that standard definition upscaling to 4K is more affected. I've had to lower NGU settings down from Very High to High (luma) and drop "reduce compression artifacts quality from "very high" to "high" to make things playable. Render and Present queues will go no higher than 6, even if set higher. Upscaling 720 or 1080p material to 4k, the GPU queue will not fill above 16 now but I could max it to 24 prior to the Windows update. 720 or 1080p material at 4K still work at my old settings and render times are nearly 5 miliseconds *less* than before the Windows 10 update. Not sure if that is real or not but I'll take it. A side note, I even removed all over clocking to my rig with no change. For full clarification, I have a Ryzen 1800x @ 4.25, GTX 1080 Ti, madVR 92.14, LAV 0.71.0.16, and use the latest versions of MPC-BE and MPC-CE. I upscale everything to 4k (using profiles for different resolutions) with frame rate switching, on a LG 4k OLED TV. |

Can someone help me narrow down my issue?
I don't use my HTPC a whole lot, the last time I watched a video on it was probably a little over a month ago and I didn't have any issues. I recently updated my HTPC (Win10) to the new April 1803 build and now when I put my videos in full screen exclusive mode, I get around 4 seconds of black screen, then when the video appears there are a few hundred dropped frames within a few seconds, and then the video finally plays smooth as normal. While this is all happening, the audio is still playing back at normal speed without interruption. So basically when I enter FSE, it takes like ~8 seconds to finally start playing back normal with zero dropped frames. I'm using the same settings as before, so I'm confused as to why I'm suddenly having this issue. Maybe Win10 updated the video driver? Anyway, my specs are: Intel Celeron G1820 Radeon 7750 4GB RAM Win 10 64-bit 1803 build Latest MPC HC 64-bit and latest Madvr. I was actually using a slightly older MPC/MadVR when I first noticed the problem, then I updated them both to the latest. edit: Apparently it's Win10's new 'focus assist' feature which mutes notifications when doing select activities. When I enter FSE it thinks I'm playing a game and turns focus assist on. I turned focus assist off when playing games and it's fine now. I'll leave this post up in case someone else has this issue.

Passthrough is what I use now.

Same here. GTX1060, no issues after Win10 v1803. Before the update, I was running nvidia v388.59. After the update windows installed v391.35. Upscale to 4k (No HDR, No FSE mode).

If I activate full screen exclusive mode, the queues fill up properly and the display rate changes correctly but the composition rate is stuck at 60Hz. This causes incrementing presentation glitches. If I go windowed, the composition rate goes back to mirroring the display rate. Done troubleshooting shooting for tonight. Everyone have a good day/evening!

Oh right, sorry. You don't have an HDR display. Do you have the brightness all the way up? I would not like to use a display at 500 nits for SDR content.
On that display you would definitely convert to SDR, probably "process HDR content by using pixel shader math" on default settings but with peak nits somewhere between 400 and 1000 (or lower, where you like it).

If your brightness is at 30% then don't using the "500 nits" marketing as a data point, it is probably closer to 120-180 nits. It is 500 nits at 100% brightness (and nits is not linear with brightness).
I thought that "let madVR decide" would be the same as converting to SDR with your display, it converts to SDR with pixel shader math on SDR displays and does passthrough on HDR displays. That said maybe it does do something different, ignoring or overwriting bad metadata comes to mind from past discussion. We do know the paths are different, based on a recent bug that had an effect when set to convert to SDR with pixel shaders but not when using let madVR decide.

Screenshot of the problem I have with Win10 1803 and MadVr.
Sorry for the bad image quality, but I used my phone to take a screenshot of a episode av SG-1 to show my performance problem with MadVR in the new 1803 build of Windows 10.
The MadVr settings i use here worked perfectly before the Windows update, with no dropped frames. As you can see from the screenshot, is that after only a minute or so, there is a lot of dropped frames. Again, I have also tried 3 different nVidia drivers with no change. 388.13, 391.35 and the newest 397.31 drivers. So there seems to be a problem with the 1803 update to Win10. Edit : Uploaded a smaller image.

I could try, but again these are the same settings in MadVr I used before the update to Win10, and I got no dropped frames back then. So why change to normal queue sizes?
