Question / Help 4K Canvas size "stutters" even with a 5960X + gtx980

Hello,

I currently play on a 1440p monitor in a dual PC stream setup. On the stream PC, whenever I try to set the canvas size to 3840x2160 (so I can do a 2:1 downscale and get 1080p), the preview window always seems to lag and only display 15fps or so (even with the downscale option selected). Furthermore, the stream also only receives ~15fps.

The CPU in the streaming PC is a 5960X. I thought originally it might be due to OBS needing more power to "compose the scene," so I installed a gtx 980, but still have the exact same issue. Whenever I set the canvas size to 1440p with a downscale to 1152p, this problem does not exist and the preview window/stream both run at 60fps.

Anyone have any idea why this might be happening?

Thanks

I'm starting to think this just might be a limitation of OBS itself. Could someone else try setting their canvas size to 4K to see what happens? Thanks.

Can't believe I forgot to include my log. Here is a fresh log file exhibiting the problem that happens either previewing/streaming at a base of 2160p.

Hello D2ultimta, I tried your suggestion and found that the "lag" isn't as severe, but it's still noticeable. With your settings, the preview window/local recording appears to be getting ~43fps.

In case it matters, the local recording is being saved to a Samsung 840 Pro ssd that is separate from the boot drive.

Do you think these hiccups with ultra high resolution are just a limitation of OBS? Thanks

I can only get OBS to record 4k@30fps~ anything higher and it will chug. Shadowplay is capable of recording 4k@60fps fine for me, so I also want to say that it's a limitation of OBS. 4k is really a large resolution so there are bound to be growing pains with such things. I know you aren't recording at 4k, but I get the same results as you if I also downscale while keeping the base res at 4k. I use a GTX 970 with a 4770k for reference.

Floating, are you using the 32 or 64-bit OBS?

Looks like I might have to hold off on making the switch to 4K.

Gotcha. So you're using 64-bit on a single PC setup while I'm using 32-bit on a dual PC setup--I figure we have all the bases covered there. The only thing left to do is wait for one of the devs to come back to this thread and comment. Being on the bleeding edge is terrible haha.

That's what I figured too, R1CH. It's a pretty beefy dedicated stream PC. I thought it might be due to me using the 32-bit version and it only detecting 4GB of system ram, but Floatingthru said he has the same problem while usign the 64-bit.

My CPU usage never creeps above 60% at those settings either. I guess I'm stuck setting my canvas to 1920x1080 and shrinking down the 1440p capture into that space? I wanted to use a 2160p canvas size with my 1440p capture stretched out to fit that so I could then benefit from using the downscale filters when converting to 1080p for my stream.
