Shadowplay DOES cause input lag

[Perfect-Reflexes]

I'm playing Call of Duty at a fast pace. My controller is wired in.

I can feel the instant delay in my input. I use a high sensitivity, at with Shadow play on, the movement of my aim becomes floaty.

As soon as I disable it. I get that instant responsive feedback.

I do want to record my stuff. Will having a dedicated recording device solve my issue? Ie like a Elgato external recorder?

Yep, it does. I have the same in cs2, whenever im recording or streaming over shadowplay i never can aim fast enough as the aim has noticable delay and feels heavy/clunky. Thats why shadowplay is OK for casuals but not for professionals or competitive players. ALSO the shadowplay input lag diminishes with GPU performance but never fully.
I personally "solved" it by "streaming" by recording externally by high speed action camera cooled by a 12cm fan behind it. And shadowplay im using for recording in post-production only (from replays to compare server-client diff). However this is not usable solution for streamers with different needs
Another solution is 7900X3D in NUMA mode /behaving like 2 separate cpus - it behaves like separate 7800X3D for gaming and 7700X for streaming/. And CPU streaming aka OBS. However i cant give you a practical experience as for my needs i need off-screen record (im not streaming for single digit observers audience, but recording for technical purposes like showing up crappy netcode, desync, delay, diff, output lag... which require at least 2 sources to compare - server sided replay and off screen client recording "what you really see and why nobody believes me i couldnt see the opponent while spectator did stare at him literally an hour").

I have an 7900X and it does not matter that I separate OBS on CCD1 and cs2 on CCD0 performance is still affected for some reason. Process lasso and reserved CPU sets and turning off Psycho Visual Tuning ect it's still affected checking benchmarks and I can feel the difference in input lag even though everything should be separated, however it is x1000 times better than having any other type of setup regarding recording. Only thing that is unaffected is 2nd "stream" pc but has other issues, for example there is no DisplayPort capture card so depending on monitor refresh rate it's not useable with HDMI + 360hz. Also mirroring on windows is bugged unless they fixed it in windows 11 but also, windows 11...
