Single‑ and Dual‑PC Issues With OBS Recording
(I tried to keep this as short as possible, so let me know if you need more details.)
I have a dual‑PC setup and also use consoles.
On my gaming PC I use an RTX 5090 with two 1440p monitors (one at 240 Hz and another at 155 Hz, set to 120 Hz).
When recording directly on this PC, OBS recordings are not smooth at 60 FPS. They look like judder, lag, or heavy stuttering — I’m not even sure how to describe it. Some recordings stay like this the whole time, others start smooth and then randomly get choppy, even when the game is running perfectly at high FPS or locked to any FPS.
Using my two‑PC setup doesn’t help. I have two capture cards (Elgato 4K60 Pro MK.2 and 4K X). The MK.2 used to be acceptable, but after upgrading my setup nothing works properly.
On consoles (PS5) through passthrough I notice small spaced stutters, but nothing serious — on the MK.2 they happen more often than on the 4K X.
I don’t want to use cloning or passthrough because I want to take advantage of my high‑FPS PC. I did test both with matching refresh rates and other adjustments, but tearing still occurs, so those options aren’t viable.
Using OBS projector to feed the capture card works for a few seconds or minutes, then both preview and recording visually drop to around 20 FPS and become completely horrible. After a while they randomly become smooth again. Restarting the projector or disabling/re‑enabling the card doesn’t fix it.
There’s no “lag in rendering” or “encoding overload” in OBS, nothing even close to that on either PC while recording — no high usage issues.
