They are both around the 1916 x 1040 mark which causes me massive frame drops and repeats from the outset. I was able to fix this by changing the quadrupling setting of image upscaling (I have mine set to NGU Sharp high) from 'Let MadVR decide' to 'only if scaling factor is 2.4 or bigger' Once I make that change both of the files with unusual resolutions play perfectly, however I was a little confused as in your guide I understood it to suggest that 'only if scaling factor is 2.4 or bigger' was the default if we select 'Let MadVR decide' Have I possibly misread or misunderstood the guide? Or is this a potential bug in MadVR?Well, thanks for the compliment. If you can believe it, I mostly edit this guide for my own notes. I just developed the habit of researching a topic and writing a guide. I started sharing the results if I thought it was beneficial.
Thanks again
The image quadrupling issue appears to be a mistake on my end. If double again is selected, then the scaling factor is 2.4x. If direct quadrupling is selected (which I think it is by default), then quadrupling is activated if any upscaling after doubling required. There was a request to fix this but it hasn't happened yet. So you could fix it by selecting double again or only for 2x scaling factors.
Thanks that makes perfect sense and does indeed fix the issue.
I have another little issue that is confusing me right now and that is some 720p 29.97fps material that I just cannot play on my 4K screen without frame drops, despite having a profile that uses NGU sharp low across the board (as opposed to my 23.976 profile that is set at NGU sharp high. The queues are filling fine so I'm not really sure what the problem might be.
Any thoughts on how I can troubleshoot this further?
