<< Solved >> GPU for 4K editing

[scottkendall]

Tried the dummy141 kext too, at first it rebooted 2 times, then it booted to desktop but the video playback is still lagging.

Try reducing the FPS really more frames then 60 is pointless unless viewing on 120hz monitor. But you might just need a CPU/motherboard/Memory upgrade. What does your activity monitor look like when you are trying to run this?

Gopro 1080P @60FPS works fine but 2.7K and 4K have too much lag... By the way sometimes I need higher FPS videos for slow motion... Otherwise I shoot @ 30/60 FPS only

%CPU goes up to around 490 and Memory goes up to 390 during playback.

(Just for the information 4K videos shot with DJI Mavic Air and DJI Mavic Pro 2 are playing smoothly)

So looks like what ever the Gopro is encoding in is smoking your CPU, and it is not even touching the GPU. I am guessing that your playback app does not use the GPU, it also likely is not using the hyper threads but that would be expected. Your memory however, looks fine at least for what you are doing.

Yeah, if IINA is using so much CPU, that's a sign that GPU is not being used.

@scottkendall , @pastrychef

Any suggestions for forcing the GPU to render the playback...??

I tried VLC too, but %CPU goes up to around 550 with that.

Try installing one of the dummy kexts... There are a few of them floating around. This one worked for my RX 560.

with this Kext %CPU dropped to 12 for VLC app and all the videos are working fine, but with IINA app its still the same (Is there a way to force the IINA app to use GPU ?)

Thanks guys

Why does Graphics says N/A ..... ??

That is perfect that means at least for Videoproc it is using the DGPU. If it was using quicksycn to use an IGPU then it would say what version of IGPU that you are using.

Maybe that app only knows how to use software encoding/decoding meaning it uses your CPU to do encoding/decoding. instead of the DGPU or the IGPU.
