Had CPU overclocked to 4430MHz with an GPU Nvidia 960 GTX Ti 4GB, that setup worked just fine for 1080p but poorly with newer higher definition movies like 2160p (SDR) and not at all with HDR material. Got an GPU Nvidia RTX 4060 8GB. Plugged it in and the PC refused to start... it took a while before I realized the CPU was the bottleneck. Clocked down to 3813 MHz and all OK. But... higher definition content weighs down the CPU heavily, sometimes so badly that video stutters and becomes unwatchable. GPU uses ~ 35-50%. But no crashes, however, some HDR material can still be watched, I don't understand why some work and others don't, can only guess that the encoding of the movies plays a role? Using madVR with various mediaplayers depending on material. |

It's been a while since I changed anything in the LAV configurations, new settings made a big difference. Just tested some videos and from going from CPU load ~80-90% and GPU load ~35% to new settings CPU ~30% and GPU ~60%. And even some video that with old settings stutters now floated on just fine! Perfect! |

I've started using the driver restart utility that comes with CRU when I want to watch something, seems to help. If I don't then glitches just keep ticking in madvr, this usually happens when I've left the computer on for a while or it's been woken up from sleep.

I very much doubt aurimas666 watches video without vsync
If you're using a dual GPU then I'm guessing it's a laptop or some brand name pre-built computer by Dell or something. I would strongly recommend getting out of those ecosystems and doing your own build with proper desktop form factor parts Last edited by flossy_cake; Yesterday at 05:24. |

Hi, regarding my workaround, it’s the “Hardware-Accelerated GPU Scheduling” setting that needs to be disabled in the Windows graphics settings, and you must restart after disabling it, otherwise it won’t work. The “composition rate” drops to 23Hz after 10-15 minutes, but no more stuttering or glitches. (thk to flossy_cake)
For your information, when I disable VSync, it works perfectly (well, with the screen completely torn, of course). So now, I’m leaning more towards a problem with VSync. I enabled triple buffering to see if it would help, but it doesn’t. I still have a minor issue where the screen suddenly goes black, switches to windowed mode, and then comes back or not, like an auto-detection of the screen. You can see it in the “devices” of madVR, for example, I have more than 40 “identification” lines for my projector. (I don’t remember how to disable auto-detection of monitors in Windows). |

Yes, MPC-HC always has Vsync ON in NVCPL. Been using it like that for years with no issues.
HAGS also was ON for the whole 2 years since switching to Win 11, but with 24H2 upgrade something has changed under the hood and HAGS became a problem. These are just my observations, pity this doesn't fully solve your problem. |

Here is the real solution: the “composition rate” remains perfectly stable, and the fans are much quieter, at the cost of a slightly increased rendering time on this scene by 2 to 3 ms. follow these steps:
On the “.exe” file of your playback software, right-click > Properties > Compatibility > check “Disable fullscreen optimizations”. |

Obviously GPU decode is way more efficient and use 1/50th of the electricity as you've discovered. Setting to dx11 uses the hardware acclerated decode blocks.

In my case it was very similar with MPC-VR during some brief comparison. After several minutes in, the OSD's frame time graph on the bottom jumps from stable line at around 25% level to ~75% and looks square shaped kinda like ECG. Of course this resulted in heavy stuttering very much like with madVR.
