Question / Help OBS video contrast flickering and lag

Hey everyone,

I've been using obs for a while now but since I made some upgrades to my PC (16Gb RAM / 4Gb MSI R9 380 Gaming) it's been lagging a lot more and it also started to flicker a kind of contrast blip over the video when I preview/record Minecraft.

I use Game Capture which I use for all my games, most of the games have some form of lag at times but not to the extent Minecraft gets.

Thanks if anyone can help :)
 
Well the first thing I notice is that it's an APU with two cores -- APUs are pretty notorious in their lack of performance, though for a two c ore system yours is pretty fast. Still, 1600x900 is probably going to be more than you can handle, as is indicated by the skipped frames count. Also, 1000 bitrate is going to be way too low for that resolution. You'd need more bitrate for that.

Best suggestion I can give to prevent lag is to scale the output down more -- set downscale to like 1.5x or more to prevent lag, then 2000 bitrate ideally at the very least (if streaming).

Also, if you're just recording, I'd recommend checking out the multiplatform version instead as it's easier to configure for recording, it has per-configured recording options that automatically sets up the encoding for high quality recordings without any need to enter in bitrate or anything. I'd probably still recommend scaling down, but you can also use the low-cpu encoding option if you want to try to encode at higher resolutions (at the cost of bigger file sizes)

As for the flicker, not sure. I'd probably have to see a video or VOD.
 
Thanks for the response Jim, would there be an alternative option aside from switching processors? I do plan on switching to either the i5 4690k or the i7 4790k but not for a few months or so.

How would it perform if I used a capture card, I.E an avermedia HD or Elgato?

Also I will try and upload a video to my old youtube channel so you can see what I mean.
 
A capture card would probably not help if the fundamental issue is encoding. It would actually probably make it worse.
 
I'm pretty sure the problem is actually coming from the R9.

I've seen several reports of this sort of flickering and they're all coming from radeon R9 graphics cards.
 
Hi @Jim!

I have the same problem right now, but i don't have a APU.

CPU: i5 4690
Videocard: Sapphire r9 380 Nitro.

A lot of r9 users have this problem, is there already a solution? It is important for me!

I like to hear from you.

Best Regards,
