This works with switchable graphics in laptops, but not with two dedicated graphics cards, not that I know of anyway.

Do you mind showing me the same thing as super-xbr 100 vs ngu aa low? I'm curious if the low setting is any better. |

NGU AA low vs Super-xbr 100 AR
Super-xbr 100 is a nice light weight option and my previous favorite but at 100 I feel is a tad sharp which you may notice as I did, at 75 however it should look fairly similar to NGU AA low. Last edited by ryrynz; 25th November 2018 at 02:18. |

Request for implementing proper 3:2 pulldown
From what I can tell madVR doesn't do 3:2 pulldown properly (see more technical details below). That is, if I play a 24fps video on a 60Hz display, it doesn't seem to show a regular cadence of AAABBCCCDDEEEFF etc.
A few points I'd like to make in favor of fixing this: Many TVs can automatically do reverse pulldown if the cadence is proper and can show the video without judder. With an unpredictable cadence like madVR appears to provide, this isn't possible. So, why not just switch the video mode to 24Hz? One, it takes a few seconds for some TVs to switch (blank screen while it does so) between modes, and two (this may be uncommon) some TVs have different input lag at 24Hz versus 60Hz, so the lipsync setting on a receiver needs to be regularly adjusted back and forth (mine has a difference of 110ms). Further, some users may have a screen that does not support 24Hz and are used to this type of judder (e.g., North American users), so don't want to devote the processing power to enabling smooth motion (or are more bothered by the smooth motion artifacts that this judder). The current implementation is more jarring than typical judder as it appears to be more unpredictable. My methodology: 1. Download the test here: https://www.rtings.com/images/test-m...15/305_24p.mp4 2. Ensure your screen is set up to reverse the 3:2 pulldown. On many Samsung TVs, for example, this can be done by turning on Auto Motion Plus, Custom, setting both sliders to 0. If your screen can't do this, you can still run the test, it will just have a different ideal result. 3. Play the video in MPCHC with madVR output. 4. While playing the video, take a 1-second exposure of the screen (this can be done, for example, using the Camera app in Pro mode on many recent Samsung phones) Ideal result: If your screen does the pulldown, you should see 24 equally bright squares. If your screen does not, you should see a regular checkerboard pattern. Result with current madVR: Squares appear to have random brightness with no discernible pattern. Result with YouTube in Chrome browser (search rtings judder test), YouTube app on AppleTV, Infuse 5 on AppleTV, Windows 10 stock media player is the ideal result as above. So, madVR seems to be an outlier with regards to this support. If I use Handbrake to set the video's FPS to 60, everything looks correct in madVR, so seems clear it is the 3:2 pulldown algorithm that is at fault. |

Hi there,
I'm using DisplayCAL and MadVR's test pattern generator to profile my display. I've just updated everything to the latest version, including video driver (GTX 1050Ti). MadVR's patterns are constantly flashing on screen, there is a double flash every three seconds. I have never seen this before. Is this intentional/known/am I doing something wrong? Thanks! |

there are not a lot of vega cards out there is considered an all over pretty bad card for consumer use.
even the 56 can spike to ~600 watt for an relative long time. and it is unclear if AMD makes any money with them. so not that easy to find a user with it. it could be much faster for madVR use than a 1080. |

I'd like to update my last post
I found that the flashing only happens when FSE is enabled. I've now disabled it and all is good. Which takes me to the following question: is FSE still a good idea these days? I believe I read comments suggesting it's not really needed anymore. Thanks |
