{% capture content %}Streaming with more than one PC has been the leader in H.264 encoding for years, but NVIDIAs Turing and Ampere generation has put a significant dent into that lead. The new generation of GPUs with the brand new encoder brought comparable quality x264 medium – if you can find a GPU that is. Let’s take a look at what’s needed to set up your stream for massively improved quality.{% endcapture %}{% include blocks/paragraph.liquid content=content %}

{% capture content %}Modern OBS Studio has two ways to achieve the expected quality: the built-in NVENC H.264 (new) and the addition from StreamFX called NVIDIA NVENC H.264/AVC (via FFmpeg). Both Options can achieve similar quality to x264 medium, but the latter is able to exceed that and rival x264 medium/slow in various situations. Whichever you pick, both of them support zero-copy encoding, and they’re both valid options for streaming.{% endcapture %}{% include blocks/paragraph.liquid content=content %}

{% capture content %}With StreamFX's NVENC integration it is possible to edge out a lot of additional quality out of NVIDIA NVENC in many situations. This however comes with a hefty cost in complexity, and requires much deeper understanding of both the H.264 specification and NVIDIA NVENC. Most GPU generations can expect to reach a peak quality two x264 presets higher than with the built-in NVIDIA NVENC encoder. As this option is aimed at people with deeper knowledge of both the standard and NVIDIA NVENC, non-critical settings are omitted.{% endcapture %}{% include blocks/paragraph.liquid content=content %}

The old presets were deprecated by NVIDIA and now map to the new P1-P7 presets, which come with massive performance or quality boosts. High Quality is now Medium (P4), while High Performance is closer to Faster (P2).
