| Summary | 0000082: Dropped frames at the beginning of playback and/or after seeking with Smooth Motion on | ||||
| Description | When playing a file with Smooth Motion activated, madVR will occasionally drop some frames at the beginning of playback (especially noticeable when repeating the playback of a file) or when seeking to somewhere in the file. I think it happens outside of FSE mode as well, but I'm not sure about this. | ||||
| Steps To Reproduce | It doesn't happen always and also doesn't seem to be specific to a group of files. It may happen with one file now and then the next day, opening the same file may be fine, so it seems to be rather random. I attached a Debug Log where it happened only after seeking once (I think I did the seeking at around the three-second mark of the video). My flush settings are the default flush / flush & wait (sleep) / don't flush / don't flush for both windowed and FSE mode. | ||||
| Additional Information | I have madVR set to delay playback start until the render queue is full, both for normal playback and after seeking, and I use a separate device for presentation. I found that the amount of dropped frames seems to depend on the GPU queue size: at my default value of 24, I got 22 dropped frames most of the time, sometimes also 21 or 23, while at the size of 16 (I only tested this briefly), I got 16 dropped frames on the first occurrence. | ||||
