I've asked a few questions about this in the Atmos drop out thread, but I've decided to create a new thread as these frame drops are not Atmos related and my Atmos drop outs have been fixed by recent JRiver/LAV updates. This isn't the case with madVR: there is no frame drop with the 3090 as long as v-sync is set to on or the presentation queue is reduced to 1, whether madVR does the tonemapping or whether it's set to HDR passthrough. No frame drops when "use the display HDR capability" is unchecked and JRVR does the tonemapping, dozens of frame drops when it's checked and the display is tonemapping. If you send HDR passthrough, the frame drops come back. To go back to the frame drop issue, I've realised that the v-sync solution for JRVR only works when JRVR is tonemapping HDR content. This is a separate issue, most likely caused by a recent windows 11 update, so I won't discuss this in this thread (but I'm happy to hear if you have any solution to it). I still get at least one large drop out (1-3 seconds of video freeze and audio drop out, and 1-3 seconds of stutter while audio and video sync again). So this is what I've been using until now, as it works with both renderers. This isn't possible with JRVR as there is no similar option.ĪFAIK, the only way to resolve these frame drops with JRVR is to set vsync to on in the nVidia "manage 3D settings" control panel. Note that with madVR, the frame drops are not reported, yet very visible. This can be resolved when using madVR by setting the number of frames presented in advance to 1-3 (1 in my case), in the rendering settings. All I know is that it's not an issue with my 1080ti. It might have started with the 2xxx series. This isn't set up specific, it's been documented by many users. With nVidia 3xxx and 4xxx series (I have a 3090 and have tested a 4060), you get a lot of frame drops (3-5 per minute) with JRiver using the default nvidia driver setting.
