Warzone feeling laggy while streaming

Hey there!
I have googled my problem multiple times and haven't found an answer, that's why I am trying my luck here.
Problem: While streaming with OBS Streamlabs CoD Warzone feels laggy, while having good frames (around 100-120 which feels smooth to me normally - without streaming I have around 130-150 FPS with the ingame settings I have right now). The stream itself looks smooth (60 FPS).

PC specs:
CPU: Ryzen 5 5600X (haven't done any overclocking myself)
GPU: RTX 3080 Gigybyte Vision OC (haven't done any overclocking myself)
Mainboard: ASUS ROG Strix B550-F Gaming
SSD: 1000GB Samsung 970 Evo M.2
RAM: 16GB Corsair Vengeance RGB PRO DDR4-3600 (2x 8GB)
Cooling: Corsair Hydro Series H115i RGB Platinum
Power supply: NZXT C850
Monitor: LG Electronics UltraGear 27GL850-B (1440p, 144hz)
Internetspeed: Download - 216.41 Mbps; Upload - 12.85 Mbps

I am trying to stream in 1080p, 60 FPS on twitch. My PC and internet should be capable of this imo.
Lowering to 720p doesn't really change a lot except for a few more FPS ingame, but still the laggy feeling.
I have tried multiple settings recommended online, but nothing seemed to have worked.
I am also using shadow play and have a NVIDIA game filter applied (I know that drains some resources - but switching it off didn't help too much either).
Stream Labs settings can be found in the pictures.
As far as I can tell my CPU and GPU are not maxed out while streaming and as mentioned before a 3080 and Ryzen 5 5600x should be able to stream the game without a problem.

If you need more screenshots or info let me know.
I really hope someone can help me out, so I can finally start streaming and still being able to play the game normally.
Thank you already for all the help.

short ignore that you use not OBS

the issue you "feel" is the not stable Game frame rate
OBS record in fixed times every X ms
the GPU creates smooth motion , but the FPS are flexibel

if the GPU and record out of Sync (there not need to identical but same over the record time)
the issue starts if the GPU creates images like every 7.7ms at 130FPS to 8.3ms at 120FPS
so the Image OBS capture at 60FPS (every 16.7ms) is not every "change" sometime its 2 frame changes sometime 3 frames
even more the source frame goes up/down even more the missmatch is "viewable"
the display (new technologie like gsync or freesync) only show the framebuffer from GPU so you not "see" the FPS changes
but it is visible on the record/stream

so the first and basic rule for "record" is stable frame rates, for perfect result the "source" is identical to the record without delays, even bigger the delay/async even more its visible
