Hallo,

my gameplay stutters, wanted to record APEX...
GPU usage is under 95%...

Ryzen 1700 stable OC to 3.7ghz

have tryied max quality and max performance at 70000 bitrate CBR....have a lot microstutters and gameplay really doenst look smooth...

HOPE SO MUCH YOU COULD HELP ME OUT

20:07:53.565: Video stopped, number of skipped frames due to encoding lag: 901/39767 (2.3%)

20:10:18.915: Video stopped, number of skipped frames due to encoding lag: 304/3100 (9.8%)

20:23:36.625: Video stopped, number of skipped frames due to encoding lag: 287/1933 (14.8%)

You're overloading the encoder.

Don't use CBR for recording, it's mostly for streaming. Use CRF or CQP rate control with a quality setting between 15 (high quality) and 23 (lower quality). Adjust as needed until you get the performance you want, or else choose between large frame size and high frame rate, at least for a single PC setup.

You're not getting rendering lag so GPU utilization is not an issue.

hey thank you, i only could choose: CBR, CQB, VBR and lossfree (verlustfrei) hope have translated it right

would be great if you could help me again thanks!

If it says "CQB" and not "CQP" that's likely a translation/transcription error, but that is the option you want.

Constant bitrate is primarily for streaming since most, if not all, platforms require it for technical reasons.

When recording all it means is larger files with no quality improvement. CRF/CQP mean constant quality instead of constant file size, so no space is wasted. Lower value, higher quality, larger files.

Encoding lag was reduced from from 2-15% to less than 1%. Increase the CQP value until this reliably reaches zero.

Now if the issue in your recorded videos isn't OBS encoding lag, but that the game itself is lagging (is the gameplay laggy for you, or just the videos?) then you probably are getting GPU overload given that you're trying to do single PC capture for Apex at 1440p/60 on a 1080. Which would not surprise me, frankly, as that's pretty ambitious. That there's no rendering lag in the log indicates that OBS is getting access to the GPU, but if the game is lagging, it isn't.

In which case I'd say go for 30fps or go for 1080p, whichever you prefer.

"GPU usage under 95%" really isn't enough to guarantee smoothness. You really need to be 90% or lower or else you will see spikes.

THERE IS NO LAG INGAME - ONLY IN THE RECORDING!

i will try to reduce CQP value tomorrow!

if that dont work, i will try to put grafic settings down till i get to 90% or lower with my gpu usage!

IN THE CASE THAT NOTHING WORKS, COULD I PLAY IN 1440p AND ONLY RECORD IN 1080 WITH NO PROBLEM? OR ANY SIDEFECTS?

THANK YOU SO MUCH NARCOGEN, REALLY FRIELDY AND FAST HELP! DO YOU HAVE A PATREON OR SOMETHING ELSE?

(optional maybe stupid question: if i would build a second recording PC, which graphiccard would be enough for my project?)

@TryHD NO THANTS NOT THE PROBLEM! I have two 144hz monitors, one was maybe settet accidently to 120hz but even only with one monitor connected same problem!!


Would be great if someone could answear to this:
