Obs drops frames mid‑stream because your **CPU** or **GPU** is choking on the encode bit‑rate. First, hit “Settings → Video → Encoder” and switch from the default *x264* to *NVENC* (if you’re on an NVIDIA GPU) or *QuickSync* (Intel). The GPU encode is a no‑friction, low‑CPU alternative—if your GPU can keep up, your CPU frees up to run your audio DSP chain and any real‑time effects without stuttering. If you’re still seeing drops, drop the output bit‑rate or scale the preview resolution down; the GPU still has to do a 1080p→1080p encode, and every 100‑kbit extra is a new load on the GPU’s NVENC block.

If you’re locked into **x264** because you need the extra compression magic, crank the *CPU usage preset* to “veryfast” or “superfast.” That tells x264 to trade a bit of quality for speed and keeps the CPU from hitting 100 %. Monitor your system with the OBS “Stats” window or a third‑party CPU/GPU monitor—look for spikes in CPU usage when frames drop. If you see the GPU usage stay below 70 % while CPU spikes, you’re in a CPU‑bottleneck; if GPU spikes to 90 % while CPU stays modest, you’re GPU‑bottlenecked. Switch encoders, tweak resolution, or add a dedicated **NVENC** card if your board is a bottleneck.
