it is totally normal to get very high present times in this case was always the case with madVR. |

@huhn
24 frame a sec but it's based on directshow "reference time", not your system time. The reference time is from your audio source, and it is rather inaccurate and it gets adjusted quite frequently but that is what MSDN's documentation asks renderers to sync to. However, the behavior is completely different for Dx9 and Dx10 render paths! So that isn't the problem there. Did you say at some stage that it worked for you in FSE mode but not windowed? The problem I'm seeing is completely different then. I get a period where frames keep getting dropped after switching out from FSE mode. My present time goes to 20ms and frames drop like mad. |

the problem is it sometimes works so my reports are maybe totally wrong. because i didn't managed to break it in the first 5 tries. in the last test directx 9 fullscreen and windows was the mode that can drops frames like crazy I check for the present times later but all mode showed choppy playback. this screen I posted earlier http://abload.de/img/untitledmni96.png shows the frame dropping issue but the present times are fine in the last 5 sec. |

Hey! I have a problem with external subtitles (.srt and .sub files at least). I do select them with directvobsub, but only the embedded subtitles work. Is this a feature/to-do or have I missed something? Embedded subtitles work just fine, and the tray icon appears, only the "open" dialog in directvobsub doesn't. Using x64 version and have x64 LAV and x64 Directvobsub installed properly.
Also the LAV-splitters choises are ignored (loading italian audio and subtitles when selected english on LAV). Last edited by SamuelMaki; 10th October 2014 at 00:13. |

Just a quick update for all the testers (I'm very appreciative, thank you!)
I believe there could be 2 issues here with the stuttering issue. The first one, I have replicated on both NVIDIA and AMD GPUs. Intel GPU does not have this problem. Namely, after coming out of FSE mode, I can't present anything for a few seconds (some times a lot longer on NVIDIA cards). This I have attributed it to bad drivers as it is not returning from my Present() call even after I have made sure it is a new VBlank (again this happens only for a few seconds after exiting from FSE mode). The net result is you get a lot of dropped frames for that few seconds and after which Present times will go back to the sub 1ms it should be. This issue, I have implemented a workaround. The second issue may be related to 120Hz monitors only. I am not so sure about this particular one as I don't have a 120Hz monitor to test with, but I do have a 75Hz monitor. On that monitor, I couldn't replicate the problem. It could be due to the same problem too, so give the new version (2.5.3) a try. |

Regarding LAV-Splitter choices, I didn't even know there's such a thing, so I made it default to the first track for both audio and sub I'll look into that one. |

@huhn @ajp2k11
Can you try v2.5.3 to see if it helps with the frame drop and stuttering issues? I have introduced a new windowed mode rendering path for both D3D9 and D3D10. There's now an additional option in the Video Renderer settings page to choose "New windowed mode rendering path". This "new" path is actually the one I've been using all the time (with fixes I mentioned in the earlier post), so basically I've added an "old" rendering path to MPDN. Anyway, if you could try both old and new paths with both D3D9 and D3D10, I'd truly appreciate it! Some systems work better with the old path in D3D9 while doesn't make a difference in D3D10 and some prefer the new path. |

OK I've just tried an earlier version of NVIDIA drivers 340.52 -- it is definitely an NVIDIA drivers bug.
This is with D3D9. Old rendering path: With the earlier drivers, switching from FSE back to windowed mode never causes long present times but can occasionally still stutter. Latest drivers, it blocks present() when stutter occurs - this behavior was changed from previous driver version to the current one. However, they still haven't fixed that issue where FSE mode to windowed mode would cause long present times. New rendering path: Both drivers report low present() times and smoothness issue only noticeable when viewing rolling credits. For D3D10, latest drivers can appear as if it has that pull up issue huhn mentioned when switching back to windowed from FSE mode. Old driver is hardly noticeable. FSE mode isn't affected by all of these. AMD & Intel both seem happy with either rendering paths including D3D10 ones. @huhn @ajp2k11: Can you guys verify the above and see if that's the same issue you are having? EDIT: Just tested madVR with default settings and its behavior is exactly the same as MPDN's new rendering path for this particular issue. Last edited by Zachs; 10th October 2014 at 11:54. |

I don't know, just a hunch :P Maybe do some simple drag and drop system for subtitles or make the open/browse dialog to work on directvobsub if you can? Seems a lot more faster than running with madVR+mpc-hc in my opinion otherwise. |

Someone needs to report the bug to NVIDIA. EDIT: You'll notice further improvements if you switch back to geforce drivers v340.52. @ajp2k11 I bet you have an NVIDIA card with latest drivers too? Last edited by Zachs; 10th October 2014 at 13:15. |
