Just on the technology side of things, most aren't buying $900+ GPUs so 99% of the market is just drooling waiting for second hand 30 series to sell :P

On another note, is anyone else experiencing the odd frame stutter?
got a 3060, on 516.94 CPU/GPU queues 16/8, D3D11, Windowed 1 frame in advance. Flush/Flush & wait/Don't flush/Don't flush
Would be nice to nail this down but I've been living with it for a while.. Windows 11/somewhat recent driver + 30 series issues? idk..
It's not like MadVR will be updated to resolve anything any time soon, MadVR 1.0 the myth, the legend..
Is it still problem free for most?
play around with the power settings it's most likely throttling because it thinks it can get away with a lower power state.

and all GPU menufactora are pretty "bad".
the difference is asus is failing constantly the 5700 xt strig and tuf where not funny...
but so is EVGA the exploding cards where also a sight to behold.

This is a good suggestion, for a long time on Windows 10 (maybe still is an issue) people with high refresh rate monitors were complaining because they were losing FPS and performance after a "security patch".

The suggested workaround from MS was to set "Maximum Performance" in the power settings instead of "Balanced".

Would be interesting to see if this helps also.

Usually I would agree to set max power profile but there are significant power consumption gains to be had by letting it downclock. I'm watching probably around 6hrs/day video content in MadVR and web browser, so the power and heat savings adds up with the crazy electricity prices. Playing 1080p24 h.265 @ 4mbps with DXVA2 decoding is downclocking to 600mhz on GTX1070 (max clock = 1600mhz). GPU usage is only 24% so it could downclock to 300mhz @ 50% GPU usage probably, but maybe then it would be more vulnerable to dropped frames?

edit: actually even it saved 40watts * 6hrs / day * 365 days , it's about 87kwh per year which I guess isn't that much to pay for smoother performance if you're having issues.

I'll have a play then. It's pretty random It's generally more than just a single frame too, it does very much feel like it's a clocking issue. Don't want to set max performance as thats not an elegant solution, so I might just see if maximizing the GPU queue helps.

Andor has some eye candy btw.

Hello, Question about HDR settings and display peak luminance (nits) value. Do I put in eg. peak 3% window value or 100% fullscreen values?

with an unstable device it's unlikely to get accurate results so the 3% one could results in more accurate results if it is in the 400 nits range if the 3% is close to common knee points it unlikely to be every be used for real content in this case i would use a lower number.

If your display has ABL then I presume you'd want to pick a window size that represents the APL of typical video content. From memory most movies are around 15% APL so a 15% window might suit.

Thanks! Will try with my OLED display. How about with projectors?

I have zero experience with projectors, but if it uses a technology which has an ABL that reduces peak brightness as APL increases, then I presume the same general logic would apply, unless there is some other behaviour specific to projectors that I'm not aware of.

And I've just realised that figure of 15% I gave you was for SDR movies -- the APL of HDR movies can vary with each movie having a different MaxFALL (Maximum Frame Average Light Level). I'm not sure how to take that into account... perhaps we could take an average MaxFALL across a random selection of movies?

Actually MaxFALL doesn't seem very useful either — imagine if there was a fade to white scene that pushes the MaxFALL to a high value.

A fade to white would likely fade to diffuse (SDR) white, not max brightness HDR white, though. You don't want to blind people, assuming a screen could actually do that.

Yeah that's true, and as quoted here diffuse white is 200 nits -- higher than I would expect the APL would be across the entire movie.

I've seen some of those though, e.g. in the film Mother! at 1:52:10 there's a fade to 533 nits white. The rest of the film is extremely dark, so I think the author's intention is precisely to blind the audience.

Random question: how come when I set [deint=off] with 29.97i 3:2 cadence video I'm not seeing mice teeth?

because it is 2:2 or 6:4 anime or because you have software deint on.

I do not have software deint on & LAV Video Decoder's deint settings are both set to "auto".

Here are 2 clips with the following properties:
  • MadVR & MediaInfo both report 29.97fps
  • MadVR reports "cadence 3:2" when MadVR's film mode deint is activated
  • My TV is refreshing @ 59.94hz and I visually observe the classic 3:2 "judder"
  • I can step through each frame with ctrl+arrows and count 24 unique images before the timecode ticks over 1 second

soft telecine or what ever this has no interlaced frame in it.
