    UHD Ripper Slower FPS with "Direct render to video" when selected

    Just installed a Nvidia 1050 into my system to start working with h265, and I have noticed that when I select "Direct render to video" in the subtitle mode it slows down the encoding to 8.5 to 9 FPS. Also lightning-shrink is not enabled and I only have h265 encoding enabled. When I use any other subtitle mode I can get 75 to 80 FPS, and lightning -shrink is enabled. Not sure if this is a setting I need to change or the lightning-shrink is not able to work with the "Direct render to video mode". any input would be great...Thanks...

    I have not seen any other reports of this, but that does not mean it is not happening. Please attach your fabcheck.log and a typical DVDFab internal log session where you have noticed this slowdown.

          When "Direct render to video" option is selected, hardware accelerated video encoding can only be disabled, so processing speed will slow down if it's accelerated before.

            Thanks for the information, I always used Direct render to video for all forced subtitles. Will faster encoding be something that can be added in the future with Direct render to video option? Thanks.
