i have an problem with white dots every few seconds in the picture, when ripping uhd with cuda enabled. with cuda disabled everything is ok. this problem i have since i purchased uhd ripping support months ago. but i do not rip very often uhd so i thought it is a bug that time. few days ago when i was ripping an uhd movie again after months i still had the problems with the white dots. then i investigated it a little bit.
i have a zotac 1080ti gtx amp extreme with a high factory overclock. when i rip an uhd movie without over or underclocking the card, i have the white dots in the picture. but when i downclock the 1080ti gtx with -100 (seems -50 is enough but i didnt test it that much) on the core and memory and then i have no dots in the picture. the card is 100% ok, because i can gaming it and use cuda ripping on normal blu-rays whith stock and overclocked my 1080ti without the white dots. the problem exists only when i rip uhds.
the only problem i have when i rip normal blurays (with uhd ripps i also have those problems) also with cuda (with stock factory clock) is when i skip seconds or minutes with the slider in vlc for less then one scond when the movie plays again i have artifacts in the picture. without cuda and also with cuda enabled with downlocked 1080ti gtx i also not having any artifacts in the picture!
so i think there is a bug in dvdfab. does somone also have those problems? it would be good if i can rip uhds without downclock my card everytime. like i said. normal bluray ripping i do not have any white dots only artifacts when i skip seconds or minutes with the slider in vlc for less then one scond when the movie plays again.
these logs are from my german uhd and normal blu-rays. i have tested those ripping it, with stock factory clocks on my gtx 1080ti, the uhd to h.265 mkv and normal blu-ray to h.265 and h.264 mkv. the results re as followed:
when i rip the uhd to a h.265 mkv i have those white dots in the pictures the whole movie.
when i rip the normal blu-ray also to a h.265 mkv i also have those white dots in the picture the whole movie. this i didn't test before to rip a normal bd to h.265 mkv!
when i rip the normal blu-ray to a h.264 mkv i do NOT have those white dots in the picture! even if i overclock my gtx!
i think there must be an issue with cuda in connection with the h.265 in dvdfab. perhaps the factory overclocked gtx is also a factor in the issue.
i also tested this movie and 2 others few days ago with downclocking my gtx like i wrote in my first post and i DO NOT have thos white dots in the picture with the downclocked gtx.
