How much VRAM does that 650 Ti have? IIRC there were models with 1 or 2 GB. Even 2 GB is short for madVR with 4K.
clsid's right, there's some problem with the GPU, maybe some driver setting or too old driver.
If using HDR passthrough and a light chroma upsampling algo and short render/present queues, it probably should still be OK with madVR even with 4K IMO.

Another difference in the screenshot is refreshrate: 71Hz vs 85Hz
Lower the refreshrate so the GPU has to do less work. 71Hz is also smoother for video playback.

madvr settings to adjust:
gpu queue size = 4
frames to present in advance = 1

nvidia settings:
Disable GSync
Enable VSync
Power management mode = Adaptive (or Normal in latest drivers)

Regarding the v-sync in nvidia control panel, is it required to be enabled for pascal cards too?

el Filou · 9th February 2021, 20:57

One time I forced VSync by mistake in NVIDIA Control Panel on my 1050 and madVR rendering times skyrocketed and it started to stutter like crazy so I don't think you can use the same settings that are recommended for Turing & Ampere with older cards.

I see, and you have the same card as mine.

Personally, I wouldn't enable v-sync on Turing or Ampere either. Is there a situation where it helps?

Disabling G-sync is a good idea though, at least for the player.

Siso · 10th February 2021, 10:39

I tried enabling and disabling v-sync on my machine, and it didn't make a difference.

Hello!
Which HW acceleration option is supposed to be the fastest? Is it in the order of the drop-down list? I would expect native DXVA in front of copy-back.

Is there a way to conveniently compare the performance of decoding options? Particularly HW vs SW.

chros · 17th February 2021, 21:05

d3d11-native is the fastest.

LAVSplitter ignore information written after "-" character in CUE-chapters. Example:

Any feedback would be appreciated.

Starting from LAV_v0.73.1-28(I have no such issue on v0.73.1-19 and older) i got live stream issues: playback stops right after approx 8-10minutes for two hundreds HLS-streams from yandex.ru site. Example(Geo block. Only for Russia):
https://strm.yandex.ru/kal/rt_hd/rt_hd0.m3u8

Any feedback would be appreciated.

UPDATE: Fixed in LAVFilters_v0.74.1-108!

@Nevcairiel
LAVVideoDecoder[Native & Copy-back modes]_v0.74.1-32 in Win7(x64) on NVidia GeForce GTX1650 card with latest drivers gives artifacts issues. if this OS is still supported by you, I can describe the problem in details with a UHD HEVC-10 video short example.

UPDATE: Fixed in v0.74.1-87 and newer!

With CUVID hardware acceleration works well. MPC-BE, Cyberlink and MainConcept accelerates via DXVA2 well too.

Corrected in 0.74.1-87 - thanks.

My message #24298 was about exactly the same issue!

@Nevcairiel
Starting from LAVSplitter_v0.74.1-34 i got issues after seeking to the beginning on HLS VideosOnDemand, now playback is starting but in fact, frames are output that do not correspond to the beginning position, but those that were at the time that was before the rewind to the beginning. On v0.74.1-32 and older LAV version I have differ behavior, it just didn't start to play media(i didn't hear sound and see only one frame that were at the time that was before the rewind to the beginning. And I liked this behavior better), example:
http://demo.unified-streaming.com/vi...m/machete.m3u8

Seems it looks like something similar with the problem here:
https://github.com/Nevcairiel/LAVFilters/issues/306

Any feedback would be appreciated.

UPDATE: Fixed in v0.74.1-98 and newer!

Reverting 9fbf56d does fix that seek issue.

There is a reason for this check. Reverting it just breaks other cases to fix one thing, instead of investigating why it fails. Which case is more important, the one the complained the most recent?

gfxnow · 27th February 2021, 06:52

Why no new release in 2 years despite so much activity here?
