NEW: Present Queue for JRVR Video Renderer

<< < (4/15) > >>

I haven't touched the nvidia control panel in a while. Vertical Sync now has some new modes, including "Fast" mode, which is advertised as being really fast like Vsync off, with no tearing like Vsync on.
Instead, I see tearing with JRVR, and excessive GPU usage. Sticking with application controlled.

again. no drops or repeated frames or glitches during movie rendering and that with or without the use of hardware accelerating video decoding. both are perfect. only a glitch when choosing subtitle. Also if one go forward and backward on a movie(seeking) the movie ending up with freezing completely and I Am on latest version ...15. That dont bother me. Now it has very good rendering, the other stuff will be fixed in time. Very good Job by Hendrik!!

Hello, I believe I found a problem using this new Present Queue feature (apologize if somebody already reported it).

The good news is that the video playback is very smooth without any hicups on my side, so good job here! But, some times after the start of video playback I cannot access the OSD to take any actions such as changing audio, subtitles, video profile, etc - the system simply ignores the remote control commands - I then have to press exit (interesting that this is a command that never fails during playback), and they start playback again - about 50% of the time I can trigger OSD and the other half it does not open during video playback. It almost feels like a process priority mechanism is taking place.

This was working fine on MC32 on the same system, so I am sure it is a new problem.

I have tried "fast mode" too and rendering stops in the end. but no tearing this time, so this mode does not work and is also not needed either as "on" work very good. Stick to vsync "on". Fast mode is not new. It has been available since 2016 I think.

I have recently upgraded my Nvidia 1060 to a 4060 and have encountered a driver issue with JRVR.
I get no frame drops at all with JRVR/Videoclock with the 1060 with any version of the Nvidia driver.

I get frame drops with the 4060 with any driver greater than 537.58 (including the latest 560.94).
The frame drops are more pronounced on 50 fps material but to put them in perspective there are only generally about 1-2 drops per hour (but can be more).
Using the 4060 with the 537.58 driver I can play a 3-hour 50 fps video without any frame drops (Present Queue enabled).

I've attached a log showing the issue FYI (the drops always look like the one shown in the attached log) and would be grateful if Hendrik could have a quick look to identify what is happening.
