Question / Help Low amount of encoding/rendering lag

Hi Everyone,

I'm new to streaming and currently been messing around with both NVENC and x264 medium on a single PC:
My GPU is a 2080ti and my CPU is a 3900x. In both instances my GPU or CPU are never maxed out. I also stream at 900p and 8000 bitrate.

Overall the stream looks great imo with both x264 and NVENC.

Here is the URL to the entire log of the night: https://obsproject.com/logs/ea8fKfQ3adJsY7ED

Encoder: NVENC (new)
Rate Control: CBR
Bitrate: 8000 Kbps
Keyframes: 2
Preset: Max Quality
Profle: High
Psycho Visual Tuning: Enabled
Max B Frames: 2
Example: https://www.twitch.tv/videos/576529578

23:08:27.349: [rtmp stream: 'adv_stream'] User stopped the stream
23:08:27.349: Output 'adv_stream': stopping
23:08:27.349: Output 'adv_stream': Total frames output: 470780
23:08:27.349: Output 'adv_stream': Total drawn frames: 470851 (470877 attempted)
23:08:27.349: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 26 (0.0%)
23:08:27.350: Video stopped, number of skipped frames due to encoding lag: 150/470794 (0.0%)

Encoder: x264
Rate Control: CBR
Bitrate: 8000 Kbps
Keyframe: 2
Preset: medium
Profile: High
x264 Options: rc-lookahead=60 trellis=1 direct-pred=spatial
Example: https://www.twitch.tv/videos/576572471

01:23:24.499: [rtmp stream: 'adv_stream'] User stopped the stream
01:23:24.499: Output 'adv_stream': stopping
01:23:24.499: Output 'adv_stream': Total frames output: 481865
01:23:24.499: Output 'adv_stream': Total drawn frames: 482005 (482028 attempted)
01:23:24.499: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 23 (0.0%)
01:23:24.499: Video stopped, number of skipped frames due to encoding lag: 141/481951 (0.0%)

My question is, even though everything seems fine, I get a real low amount of rendering/encoding lag. Like lucky to maybe hit 0.1% Is this something to worry about?
I only have 1 scene enabled, with the game captured, alert box and webcam. Enable preview is disabled.

Not really sure if this is something I should look to fix, or just keep on going.

Many thanks.

141 out of 481951 is about one frame per hour at 60 fps. This is not visible and nothing to worry about. This could happen in the instant when some app switches from windowed to fullscreen, or if a game does map loading, or if you start an app mid stream and capturing for that app is beginning, or some other kind of short usage peak.
