OBS Studio 28.1.0 changelog:

Added NVENC AV1 hardware encoder on Windows

Currently only works with the NV12 (OBS default) and P010 color formats
Currently does not support the "rescale" feature in advanced output mode
Only available for RTX 40 Series video cards from NVIDIA

Updated NVENC presets

Presets have been split into 3 different settings: Preset, Tuning, and Multipass mode
Presets are now P1-P7, lower numbers being lower quality, higher numbers being higher quality. Note that higher presets may incur higher GPU usage which could impact the performance of games running simultaneously with OBS. The number of simultaneous NVENC encoding sessions may be lower when using the highest presets. OBS will automatically map your current NVENC settings to the closest preset when upgrading.
Tuning is used to determine whether to prioritize latency or quality. It has three settings: High Quality, Low Latency, and Ultra Low Latency.
Multipass Mode is used to determine whether a second pass is used in encoding, and has three settings: Disabled, Quarter Resolution, and Full Resolution. Enabling this will give higher quality at the cost of more GPU resource usage.
