Here's the deal, I recorded on "veryfast" preset with okay bitrate back around 1 year ago, everything was fluent, without a hitch.

Now it stutters my game if even have OBS Launched while i play it with the "veryfast" preset..

Before I could run a stream open and have obs recording now I don't have anything else running in the background and it does what i described above..
Even worse when I record it stutters my game even more and gives me -150 fps loss..

Here's the log https://pastebin.com/RZwEMEFT

If i put in on Superfast it's okay and great on ultrafast but I don't see why I should with my pc..

Turn gaming mode off in windows' settings
Use simple output mode
indistinguishable recording quality
FLV format (there are precisely ZERO good reasons to save directly to mp4)
software low cpu use encoder.

Appreciate the insanely quick response.

Tried it, there seemed to be no lag apart from a stutter or two, still getting up to -100fps drop but on average it seems to have fallen only -50, do you have any insight as to why this happened though?
The game's CSGO, we all know it's poorly optimized and gets worse with almost every update, could it be that?
Here's the latest log if it helps at all: https://gist.github.com/anonymous/0085ba31548b7a10f8a98b97496f0685
or is this as much as I'm going to get out of it ?

Do note i changed the filetype to mp4

Don't. Like I said above, there are precisely ZERO good reasons to do so.

as flv wasn't loading properly for me in VLC

Then you have something screwing things up.

Sony Vegas wasn't even able to import it ..

Remux to MP4 AFTER recording to FLV or MKV.

And turn gaming mode off in windows' settings.

I've had gaming mode turned off in windows from the start :P
Also now recording since you are not recommending MP4, may I ask why that's the case though, is it just the filesize?
Latest log if there's anything you think I can improve on, also what bit rate would you recommend, I've read that there is no significant difference in anything above 18K

No. It's that if your recording stops non-gracefully, the entire mp4 becomes unusable rather than just the final 2-3 seconds of it if you record to flv or mkv.

You may need to use hotkey based window selection rather than capture any fullscreen since that log just shows game capture trying to capture chrome.

Hang on, how am I suppose to record my mic and application in simple mode? Also I've tried using any one of the filetypes you recommended, none of them are compatible with SV

You can't do multitrack audio in simple output mode.

As for settings, https://obsproject.com/forum/resour...lity-recording-and-multiple-audio-tracks.221/

Right, well i don't know if I should have mentioned this sooner, but I do have a latest gen Nvidia GPU, tried NVENC H.264 again now that update 20.0.1 hit.
It seems to record flawlessly with no lag but still a few fps drop, so I'm going to stick with that, mind taking a look at the latest log to see if anything I'm doing now is wrong?

Also what CQP should I actually use and should the I really set the audio bitrate to 320 like most people recommend?
