In 2026, streaming depends not only on bitrate but also on encoder efficiency. Here is exactly how to configure your OBS Studio for a flawless 1080p/60fps stream.
Go to Settings > Output and set the Output Mode to Advanced.
-
Encoder: NVIDIA NVENC H.264 (If you have an RTX 40-series like the 4090, this is the gold standard).
-
Rate Control: CBR (Constant Bitrate).
-
Bitrate: * Twitch: 6,000 - 8,000 Kbps (Twitch officially caps at 6k, but many Partners/Affiliates can push 8k for better clarity).
-
YouTube: 12,000 - 50,000 Kbps (YouTube allows much higher bitrates for 1440p/4K).
-
-
Keyframe Interval: 2s (Mandatory for Twitch/YouTube).
-
Preset: P6: Slower (Better Quality).
-
Tip: Only use P7 if you aren't playing a GPU-heavy game. P6 is the "Sweet Spot."
-
-
Tuning: High Quality.
-
Multipass Mode: Two Passes (Quarter Resolution). This gives you the best quality-to-performance ratio.
2. (Clarity Settings)
-
Base (Canvas) Resolution: Match your monitor (e.g., 1920x1080 or 2560x1440).
-
Output (Scaled) Resolution: 1920x1080.
-
Downscale Filter: Lanczos (36 samples). Since you have a 4090, you can handle the sharpest filter.
-
Common FPS Values: 60.
- Note: AV1 Encoding: If you are streaming to YouTube or using Twitch Enhanced Broadcasting, try the NVENC AV1 encoder. It is 40% more efficient than H.264, meaning your stream looks better at the same bitrate.
