Edkroket Posted July 9, 2015 Share Posted July 9, 2015 Hi all, I'm facing an very strange video issue with my X99-UD4, GTX 970 or 780 or 960 I'm playing a MP4 Format: H.264, 3840 x 2160 AC3, 4800 Hz FPS: 60 Size: 673,2 MB Data Rate: 8,32 Mbit/s Current Size: 1920 x 1080 (half) The movie stutters while playing. So it stops while audio is going on but the video moves stuttering. I've got Web drivers installed, no Cuda, have used different SMBIOS settings. It just don't matter what I do to get rid of this. I've searched everywhere but can't find anything to solve this. So if any one can give me a hint or help.? Thanks Link to comment Share on other sites More sharing options...

Edkroket Posted July 10, 2015 Author Share Posted July 10, 2015 hello what video ? link Sorry I don't have a link it's just a local file. On my MacBook Pro 13" 15 it's playing just fine and on other Hackintosh I build it runs also without any issues. I've seen GVA errors in console within QuiktimePlayer. So there has to be some software error. My guess is it's because of custom ACPI Platform for my 8-core. But I just don't know what. On the other hand when running Cinebench (105 FPS) it has high score with Luxmark OpenCL 1414. I'm not at the machine now but I will put some logfiles later here.

gils83 Posted July 10, 2015 Share Posted July 10, 2015 now look ScreenFlow 60 fps/12 Mbit/s (4k 60 fps / 2k full screen) test.zip - 60.0 MB le problème ne vient pas du GPU mais du CPU , certainement un problème de gestion d'énergie , le CPU n'accélère pas assez pour lire correctement le fichier video , regardes aussi ton lecteur média player , il se peut aussi comme MplayerX qu'il rencontre des décrochages en .mkv , donc peut-être convertir le fichier en .mp4 pour le lire avec QuickTime the problem is not with the GPU but the CPU, certainly a problem of energy management, the CPU does not accelerate enough to properly play the video file, so look at your media player player, it may also be that MPlayerX meeting stalls in .mkv, so maybe convert the file to .mp4 with QuickTime to read PS : use FX 8320E/ HD 7950 (opengl 73 fps/opencl 1930 pts LuxMark Sala) Link to comment Share on other sites More sharing options...
Edkroket Posted July 11, 2015 Author Share Posted July 11, 2015 I have solved it! It seems that I had to have Generic USB kext and also run CPU at higher stock-rate. Running at 4.0 now with the kext and movie plays as smooth as butter.! Thank you all! 1 Link to comment Share on other sites More sharing options...
