Stefan Duenkel Posted May 31, 2018 Report Share Posted May 31, 2018 Hey, I am a beginner in watchout. so sorry if some of my questions are stupid. i have a problem with 4kq60 playback on a Display-PC i just tweaked for Watchout. i have the following PC-components: Motherboard: MSI H270 PCmate ATX CPU: i7-6700K Drives: Intel SSD SATA for OS, Samsung NVNe SSD 960pro M.2 for WO GPU: AMD Radeon pro WX7100 i tried a lot of different codecs: h.264, mpeg2, hapq, hap with 60fps i get some seconds of smooth playbackt than it starts to stutter ( mpeg2 with 80 Mb/s runs smooth for some minutes , then starts to stutter ,too) Hap with 30fps runs smooth I know that this is not an high end Display PC, but all i need is playback and loop of one 4k file with 60 fps. Shouldn't that be possible with this PC? or am i missing a bottleneck in this configuration? Thanks for your help. Stefan Quote Link to comment Share on other sites More sharing options...
Dataton Partner Walter Posted May 31, 2018 Dataton Partner Report Share Posted May 31, 2018 WO6 I presume? This should indeed (at first sight) be no problem at all. Are you sure watchout is installed on the m2? Did you measure it’s read speed? How long is the video file you’re trying to play? HAP or HAPQ should play a few 4K streams without issue.

Thomas Leong Posted June 1, 2018 Report Share Posted June 1, 2018 Additionally - 1. Win7 or Win10? 2. 4K is not possible even with dual-link DVI, so you must be connected to your Display monitor/projector via DP-HDMI Adapters or DP-DP. If DP-HDMI Adapters, are they HDMI 2.0 or 1.4? You need HDMI2.0 for 4K at 60. Quote Link to comment Share on other sites More sharing options...
Stefan Duenkel Posted June 1, 2018 Author Report Share Posted June 1, 2018 Hey Walter, Thanks for your help Yes , WO 6. And yes Watchout is installed on the m.2. I was wondering if the m.2 slot and the GPU have to share the 16 pcie lanes the CPU supports. But if i read it right in the manual of the motherboard the M.2 SSD is connected to the CPU via DMI 3.0. so this shouldnt be the problem. i measured the read speed of the SSD an its over 3000 Mb/s. I can playback and loop two 4k files in HAP with 30fps simultaniously on top of each other perfectly , but not one with 60fps. is there a maximum of bitrate per file that Watchout supports? The 4k HAP 60fps - clip is ten seconds long and has a bitrate above 600Mb/s Quote Link to comment Share on other sites More sharing options...
Member jochri Posted June 3, 2018 Member Report Share Posted June 3, 2018 Did you checked the "syncronisation chain master" button in the display settings? Without it the system will not deliver the power it has. Quote Link to comment Share on other sites More sharing options...

The 4k HAP 60fps - clip is ten seconds long and has a bitrate above 600Mb/s Well, I’m used to playing numerous files with a bitrate of around 800mpbs at 50fps without any issues (at least 4 or so) using a dual ssd configuration so driving it of an m2 should present no issues. Not sure about the lanes but as your reading speed turns up as well as you state, this should not be the bottleneck. Watchout doesn’t have a max bitrate it can handle afaik, so.... btw, m2 is flash, not ssd, right? Or am I totally lost in the world of data carriers ?
