As usual in the modern days, many vendors have started to ship unremovable bloatware with Windows. And unfortunately Microsoft happily forcefully installs it on your System, no matter if you blacklist the "Update" or the "Device". So we'll have to take matters into our own hands, and wrangle some semblance of control and performance back. ASUS is no exception to this, installing bloatware that behaves similar to malware.
The H.265/HEVC codec is a newer codec that was intended to replace H.264/AVC, but ultimately failed due to its needless licensing complexity. While more efficient and much more versatile than the predecessor, it is also significantly harder to encode and decode.

The H.264/AVC codec is one of the oldest, and yet still one of the most versatile codecs out there. It is (relatively) simple to encode and decode, supports a variety of chroma subsampling and bit depths, and is one of the first codecs for stereoscopic video. x264 Option Lossless Near Lossless Indistinguishable High Quality Acceptable Quality Rate Control CRF CRF 0 0 to 4 5 to 10 11 to 16 17 to 22 Keyframe Interval 1 Preset ultrafast - placebo A slower preset only affects file size, quality should be unaffected.

The world called for a more efficient royalty-free codec, and AV1 is the answer. It is significantly better than VP9 at the same task, and has a significant reduction in decoding complexity, putting the complexity on the encoding side instead. Given that it is a more recent codec, support for it is still relatively small - though software decoders can handle it just fine on most devices.

A new contender in the high quality streaming field has appeared: Intel! Their current generation of encoder hardware is capable of matching (and sometimes exceeding) the fast preset in x264, while exceeding real-time speeds at that quality. This makes Intel a good alternative to NVIDIA Turing/Ampere GPUs for budget builds, and as such makes Dual-PC streaming far more affordable. Setting up QuickSync (for Streaming) At the moment, the only Intel encoder available is the built-in QuickSync H.264 encoder maintained by Intel and the OBS Project team. Using the FFmpeg variant does not improve quality, so it is enough to use...

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. Setting up NVENC (for Streaming) 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...
