Resolution
The pixel dimensions of your stream — 1920×1080 (1080p) or 1280×720 (720p). A crisp 720p60 beats a blocky 1080p60 on low bitrate.

- FPS (frames per second)
How many images per second your stream shows. 60fps is smooth and standard for gameplay; 30fps is fine for chatting and saves bandwidth.
- Downscaling
Rendering your stream at a lower resolution than your monitor (1440p screen → 1080p stream). Lanczos is the sharpest OBS filter for it.
- Bitrate
How much data your stream sends per second. Higher bitrate = better image quality but needs more upload speed. Twitch caps it around 6,000–8,500 kbps.
