Question / Help Issues with encoding lag NVENC

Hello. I am having issues with encoding lag , my pc specs are as listed , i5 3570 , GTX1070 , 8GB RAM. Videos are all recorded into an External 1TB USB3.0 HDD (tried SSD , issue persisted)

Here's the thing , whenever I try to record a video , there will be encoding lags randomly within the recorded video. Games that I've tried are , Dying Light , CSGO , GTA 5 , all of them have the same issues. I thought my pc is more than enough to be recording videos since I'm using NVENC that offload most if not all of the recording workloads onto the GPU itself? But that doesn't explain it too , since CSGO isn't a very GPU intensive game , I have all my settings set to lowest in that game except for 2x AA.

But what I am currently suspecting is that the 3 games that I have tested are very CPU intensive , so that might why it is causing encoding lags? From what I have tested , Shadowplay on the other hand doesn't seem to have issues with random stutters in the recorded footage though , even though recorded at a higher bitrate than what I am using on OBS. What exactly is causing this? Thanks a lot.

You'll need to post your entire log file, use a text file hosting site like pastebin.

Definitely something is off, but I can't tell what.

Sorry , but I've checked again , this is the entire log file that was used during that session test. Any help would definitely be much appreciated! Also , this is on a clean install of Windows , and a new Graphics card , previous one was AMD 7850 which didn't have a problem with encoding lag but it appeared later on as well , presumably by newer versions of OBS because I recalled reinstalling OBS. So I accepted that the card then was too old and weak for recordings , so I got myself a 1070 , didn't expect this to happen honestly.

Edit : Opps , i really did miss out on the code , sorry. Here's the complete one. https://pastebin.com/YeC1KYrt

Limit or sync your FPS to your refresh rate if you haven't.

I am using 144hz to game , isn't that impossible to record in 144fps? And in some games I might not be able to reach that high anyway , plus games like CSGO where I would definitely want my fps to be uncapped though.

Click to expand...

Not sure what the bd preset is, but try using High Quality (hq) or High Performance (hp) and see if its better.

Some of your settings look like they're intended for streaming, but you're saving to disk. Do you intend to stream too?

u can try fractures -> like 72fps or 36 fps

but afaik NVenc adds some lags due to how it does its magic

Sorry , I don't quite get what you mean by this , so by that I assume you're asking me to record in either 72fps or 36fps?

Yes , some of the streaming settings were set just to test out streaming , though I have no idea if there were any encoding lags/frame drops or not , because its harder to monitor as to recording.

As to the "bd" preset , I think it's the Bluray preset that i used , I'll try your suggestions soon. Been testing everything but to no avail , didn't even get any sleep last night :(

Pretty disappointed at this point , I got the 1070 solely because I could play higher quality games and some smooth recordings...

After days of trying to fix the issue , I've came down to the conclusion that recording into my USB3 1TB Seagate external HDD was the cause , I have no idea why it is happening since it has faster write speeds than my other 2 older HDD. Even my dying HDD doesn't have issue with encoding lag after I've checked. It might be something thats conflicting via USB? No idea.
