How to Optimize Your Streaming PC Encoder Settings for 2026

Encoder choice and bitrate are still the two settings that move the visible quality needle on stream — and the right answers in 2026 are different from two years ago.

For Twitch, AV1 is now eligible across most regions and uses about 30% less bitrate for the same visual quality. If you are on RTX 40 or newer (Nvidia), Arc, or RX 7000+ (AMD), turn it on. If you are on older hardware, NVENC HEVC is still the strongest fallback at 6,000 kbps for 1080p60 gameplay.

For YouTube, set bitrate to 8,000 to 9,000 kbps at 1080p60 with a 2-second keyframe interval. YouTube’s adaptive transcoding handles the rest. Going above 9,000 kbps gives diminishing returns under most conditions.

The single setting most streamers get wrong is encoder preset — the default “fast” or “performance” preset on most encoders is genuinely a step worse than the “quality” or “p7” equivalents. The CPU/GPU cost is small on modern hardware. Adjust it once.
