Hey all,

New to this so baby steps is the best way to explain stuff here. I recently noticed that when I click preview stream, my stream plays for a second, freezes, plays for a second, freezes, etc. I haven't changed anything, or at least I don't think I have, but I need some help to get this to clear up please. It just all of a sudden started doing it the other day. It was working just fine. Any and all help would be great. Thanks.

My specs are

Intel i7 4790K stock
ASRock Z97 Extreme 6
EVGA 980 SC w/ACX 2.0
8gb Corsair Dominator Ram
OCZ 120gb SSD Win10
1tb HDD Seagate
Elgato HD60 Pro (PCIE)

The log I copied for OBS is here:

This isn't directly related to your issue, but you should avoid using a bitrate of more than 2500 for watchability reasons. Many people even limit themselves to 2000 so as many people as possible can watch them.

What you're describing sounds like your stream is lagging a bit, in preview this means your CPU is having problems encoding. Are you getting high CPU usage? (Either as warnings in OBS or as a high number in task manager)

I also think it's possible that only your preview is lagging. Have you tried locally recording a stream and watching it back to make sure it's not just the preview that looks laggy?

I will knock down the bitrate and see what happens there. I only used that number due to the recommendations from the OBS website.

The CPU doesn't seem to hit any high usage. The most I see out of it is at the worst 40%, but thats occasionally. It floats around 20-30% when I preview it. I have not tried to record anything and play it back. I will check this and see what happens. Thanks for the info.

I tried messing with the settings as you suggested, but it didn't work. I went ahead and uninstalled and reinstalled the software and everything is back to normal. I'm not really sure what the problem was but its fixed. Thanks anyways.
