Ok I'll try this. Where do I set the refresh rate though?
Does it happen with SDR?
No it doesn't. 4K SDRs play very smoothly. No problem at all.
Was it working with previous versions of madvr? If yes what version?
No, I've never gotten it to work with madVR. I tried the official version 0.92.17 before and it also stuttered a lot.
What's the projector?
Have you tried connecting the projector directly to the GPU?
How long is the cable?
The Projector is BenQ HT3550 (4K). Yes, I'm hooking it up directly to HDMI port on the GPU. Cable is 3m long. It works perfectly with 4K SDR so I think the problem is with the rendering.
What is the HDD?
Check the HDD and CPU usage.
I'm storing the movie on a NAS. I'll try to play it from an internal HDD to make sure the problem is not with the NAS. My home network is Gigabit though and Windows reports Gigabit bandwidth. I've measured transfer rate before and it was more than adequate for 4K content. I'll measure the CPU, too.
