Hi,
So the last 6 months I've moved from Action! to OBS for recording games to my Youtube channel. It has been working flawlessly but in the past couple of months OBS just hasn't been working. It started out with just recording a still image with flawless audio in the background to now recording 4-5 minutes of the actual gameplay then stutter and pausing randomly mid-gameplay for about 1.5 - 15 seconds. I've tried everything from running it as admin to changing the priority, would any of you guys be able to help me out?

SPECS :
GTX 1080
16 Gb RAM
Windows 10
i7-7770

Current settings :

Don't save directly to mp4
Don't have both Display and game capture in the same scene
Don't use CBR for recording.

Can you shortly explain why mp4 is not a good option for local recording? And what should be used instead?

I'm kind of curious ^^

If the recording for any reason should fail, e.g. ObS crashes, the entire recording is ruined. Use flv or mkv instead. You can always remux your recordings to mp4 later in files > remux recordings.

It was still stuttering and lagging so I borrowed my buddies Elgato HD60s it's helping a little bit but there is still stuttering here and there for 3-5 seconds. Any advice?

The log shows encoder overload. Not sure what the cause is, but I do know that CBR isn't usually suggested for use with recording using NVENC. Are you getting the maximum possible bandwidth out of your video card?

09:47:18.988: Video stopped, number of skipped frames due to encoding lag: 563/4698 (12.0%)
09:53:04.685: Video stopped, number of skipped frames due to encoding lag: 537/3897 (13.8%)
09:55:45.238: Video stopped, number of skipped frames due to encoding lag: 379/4003 (9.5%)
09:57:33.679: Video stopped, number of skipped frames due to encoding lag: 590/2608 (22.6%)

any suggestion's on what Rate control I should use?

I think I'm getting the Maximum bandwidth out of my graphics card, is there a way to check?

According to the GPU-z mouse-over tooltips, the shown bandwidth has nothing to do with you PCI-e lanes, so just check again, if it's using all 16 lanes or just 8.

So I checked again it says PCIe x16 3.0 @ 16 1.1. when I hover over that information it gives me a drop-down menu that says it's running at PCI Express x16 1.1
