There also isn't enough resolution in the timer to tease out differences between cards that are close.

Yeah. That's why we'll just use screenshots of graphs from the log data and videos that are long enough to give good averages. I'm thinking about 2 mins. If you want to discuss feel free to msg me.
Actually let's just start a discussion thread first then once we've defined parameters then we'll make a new one for results. |

I was trying to think of a dirty way of creating a tool or at least something that was portable, something we could all use, something that forces us all to use the same settings at least, other than just using stock settings. This idea might be possible but its dirty as hell but could be refined if someone knows how to create scripts and compile exe's.
someone could create an extracting exe to do something like the following Creates a folder c:\MADVR TEST Runs a script which queries the current location of MADVR install and renames is MADVR.old extracts a proconfigured MADVR install to c:\MADVR TEST\MADVR extracts a proconfigured portable MPC-HC program to c:\MADV TEST\MPC extracts a video file to c:\MADVR TEST Runs a script which installs MADVR Runs a scripts which runs the video file so user can take a screen shot When movies closes a script renames MADVR.old back to MADVR and installs it again. Script delete c:\MADVR TEST Would this work though, would you be able to run MPC portable without setting the decoder or configure anything in MADVR?

I wouldn't put too much effort into it right now as there's a chance madshi might re-release his benchmarking version sometime in the near future. The goal imo is to simply determine average performance, not to make a quick n dirty tool providing more accurate and comparable results. We've made do for this long.. Just need to decide on content, settings, tools are reporting method.

I hope madshi does re-release the tool, I would say its more essential now than it has ever been due to the sheer number of cards and driver version available, it would be good to compare results from different driver versions as well as cards !

If you log with a monitoring tool (I've read madVR doesn't like GPU-Z and the like but I've personally never witnessed any difference in performance when it's running) and multiply the GPU clock by the load percentage, then divide that number by the max boost clock (which can usually be found in reviews, or just max out your madVR settings to find it), you can get an estimation of the relative work that is needed from the GPU for a certain madVR config.
It's not a 100% accurate evaluation but it's closer than "this GPU can probably do X scaling algo at Y source and Z output resolution"

I don’t understand your logic. The performance of the NGU algorithm translates to a benchmark of many frames as possible for certain “ideal” settings. I can imagine that an expensive graphics card may not be the winner. Let the tool determine the best cards for the NGU algorithm (=madvr) and settings. Just my 2 cents.

the 2 finalsteps currently take about 2 ms.
to make math simple if you manage to reach 250 FPS with the giving setting you are currently loosing 50% of the performance to the finalsteps this is not an accurate representation of the card. that a problem in game benchmarking too but it is far far less of an issue there we have way more steps then the finalsteps.

My GPU can't keep up with NGU doubling on low when playing low-resolution 50fps PAL content (Antiques Roadshow), but is fine playing basically all other content at even NGU high.
Is there a way to modify the upsampling algorithm when playing >=50fps content? |

Maybe rendering and queue settings influence this.

Is there a madVR setting that increases playback FPS? When using LAV Filters Megamix mid-tier (NGU medium) preset, PotPlayer's OSD information displays this:
https://i.postimg.cc/Zb7hVpst/zuikaku-S9-YJb-KMTj-M.jpg One line reads: "Output: P010, 2048x1080(1.9:1/1.78:1), FPS: 23.976->59.94" If I use another video renderer, e.g., EVR-CP, the FPS would read: "23.976->23.976" Just in case, madVR's OSD information displays this: https://i.postimg.cc/Bs7mQM1f/zuikaku-c6-Xopp-Q0o2.jpg If a madVR setting is increasing playback FPS, is that setting affected by the Windows version? The reason I ask is using LAV Filters Megamix's mid-tier (NGU medium) preset on Windows 10 to watch anime gave me 60 FPS. I switched to Windows 8.1 for reasons, and the same preset gave me 30 FPS although now it is giving me 60 FPS, even though I made no changes. |

Your refresh rate is 60Hz (you are asking your display to show 60fps), madVR in your particular case is blending frames AKA Smooth Motion (Seen enabled in your OSD)
If you are not blending frames this way say with another renderer, then you have judder as a result of having a 3:2 pulldown as frames are displayed in a 3-2 pattern. Keep Smooth Motion on and enjoy, madVR is the best renderer available for your video content so stick with it. |

Or switch refresh rate of the display to 23p if that's possible and turn smooth motion off.

So that is why I had judder when using video renderers other than madVR. madVR also has a setting to change automatically display modes. Can that setting replace Smooth Motion, and is it better or worse than Smooth Motion, which is to ask does Smooth Motion have downsides? |
