Sorry, I haven't tested it with the 2017 q4.1 version driver，And now the 2017 version of the driver on AMD's official website is no longer available for download（https://www.amd.com/en/support/previous-drivers/professional-graphics/radeon-pro/radeon-pro-wx-x100-series/radeon-pro-wx-9100） Do you have the download link for the 2017 q4.1 version that you can send to me? Either on the forum or email，My email address: karenkongvc@gmail.com Thank you so much.

In fact, The GPU usage is dynamic, But I just grabbed the picture when its usage was 18%，Of course, I also updated the GPU driver, But it is still not smooth when playing 8K@60fps. Yes, The hardware performance information in the picture is the display server. This is by remotely accessing the AIDA64 installed on the display machine to view its performance status. Thanks Artboy!

Ok I'll test it again at 8k 60fps with 16 chunks and 20 chunks，Thanks Jfk!

And now the Display is connected to 3 screens with a resolution of 3840*2160 (two of which are spliced to 7680*2160), I also tested the performance of 50Hz and 60Hz, Their performance is the same.

Oh，Sorry, I forgot the version, I have the same problem with Watchout 6.6.7 and 6.7, even 6.67 is worse than 6.7，I have tested both without setting chunks by default and setting 8 chunks when transcoding with FFmpeg, but they are all the same unsmoothly when playing，This is a temporary rental project and will not use the cluster，The current failure situation doesn't look like it's related to another VNC. Thanks Jfk!

Hi all I'm testing an 8K（7680*4320） 60fps hap video，But many times it can't play smoothly（Playing the same 8K video at 25fps is very smooth, and playing a TGA sequence with a hard disk read speed of 2400MB/s is very smooth），Below is my Display machine configuration: ● win10 2019 Pro（Version 1903，Based on win10 enterprise The optimization of the adjustment guide has all been set） ● Supermicr C9Z490-PGW ● I9 10850K ● WX 9100 ● USCORSAIR DDR4 3000 16G*2 ● Disk：Samsung 970 EVO Plus 2TB（The theoretical value of read speed is 3500MB/s, and the write speed is 3300MB/s） Unsmooth 8k video when playing： A lot of times it doesn't play smoothly, But after a lot of trying I stumbled upon a time when it played smoothly（If I want it to play smoothly all the time, I can't modify anything on the timeline, not even doing any modification just pressing CTRL+D to update it, It won't play smoothly anymore） Stumbled upon in testing how to make it play smoothly： ● Display is turned on, Production ONline（Playing is not smooth now） ● Press CTRL+SHIFT+A from the stage to enter Display machine ● Exit Display software ● Use TightVNC to enter the Display machine again and start the Watchout Display software ● Production ONline（Now TightVNC is still connected and not closed） ● Start playing video（Now the playback is not smooth because TightVNC is still controlling the Display machine） ● Close Disconnect TightVNC ● Now 8k@60fps video playback is very smooth（As long as you do not modify, edit, update, go online, and offline in Production, let it play 4 different 8K 60fps video loops for more than 10 hours, and it is still normal and smooth.） ● Even if I don't make any changes in Production, just press CTRL+D to update，It won't play smoothly anymore Display machine hardware performance information when playing smoothly（It can be seen that the peak reading of the E disk is: 892.8MB/s）： When it does not play smoothly（It can be seen that the peak reading of the E disk is: 444.5MB/s）： If it is because of the performance bottleneck of the hard disk, why is the TGA playing at 2400MB/s always smooth? As above, no matter when the video is played smoothly or not, I have not found the bottleneck of my hardware performance, so does anyone have relevant experience that can help me, thank you very much！
