What is Nvfbc capture?

NVIDIA® Frame Buffer Capture (NVFBC) is a fast, low latency desktop capture API supported on Windows and Linux. … It uses the NVIDIA GPU and the GPU driver’s capabilities to accelerate capture and deliver captured frames in GPU memory or CPU accessible memory according to the user’s choice.

What does Nvenc stand for?

From Wikipedia, the free encyclopedia. NVIDIA NVENC (short for NVIDIA Encoder) is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler-based GeForce 600 series in March 2012.

Does Shadowplay use Nvenc?

Shadowplay is NVIDIA’s proprietary recording software, that can be utilised by any NVIDIA GPU that has a built-in H. 264 NVENC ASIC block, provided the driver allows it. However, that isn’t the only thing that makes Shadowplay so special, it can also utilise NVIDIA’s proprietary capture techniques, NVFBC and NVIFR.

Which is better Nvenc or x264?

NVENC in the GTX 10-series GPUs provides superior quality than x264 Very Fast, the most commonly used x264 preset. And in the new RTX 20 and 30-series, NVENC performs better than x264 Fast and on par with x264 Medium, a preset that requires an expensive dual PC setup.

Does OBS use GPU or CPU?

Even if you encode with CPU (x264), OBS needs a minimum amount of GPU power to do the video compositing. A GT 710 isn’t suited for OBS operation at all. You will get rendering lag with it. Even iGPUs might become overloaded, if you compose your scenes with more than 1 or 2 sources.

Which is better OBS or ShadowPlay?

Difference 3: Local file recording:

OBS is also good in this task as it compresses files automatically to assist in fast processing. The best idea is to use OBS for long sessions and terrible bandwidth ranges; whereas ShadowPlay is nice choice if you have great bandwidth.

Is OBS better than Nvidia?

In many instances, OBS is better than Nvidia Shadowplay, becouse it offers so much flexibility of options, but the options for Nvidia GPUs are limited. For AMD, OBS have 5x times more settings compared to Nvidia and the quality can be better the Nvidia.

What bitrate should I record at ShadowPlay?

For 60 fps I find that 25 mbps for 1080p / 35 mbps for 1440p is the sweet spot for shadowplay. Then a non real time CPU encoder can lower the bitrate with minimal changes to quality after the fact, but if you do shadowplay at youtube’s recommended bitrates it’s not gonna be pretty. There is no «ideal» bitrate in GFE.

Is x264 good quality?

The general consensus is that x264 is still superior in image quality versus hardware encoders, though at the expense of (a little bit) more resources.

[Guide] x264 encoding is still the best, slow isn’t better and NVENC is second.

Does Bitrate affect CPU?

Bitrate does have an influence on cpu, since you basically convert more data per second. But it’s pretty minor even on lower end cpu’s unless you go for extremes (in the 100000’s). Preset, resolution and fps are of a much bigger influence on your processor.

What is x264 x265?

x265 and x264 are two different video compression standards that are used to compress video in size but still maintain the quality of the video. x264 is an earlier codec and is used in a lot of videos nowdays and x265 is a newer standard.

Does OBS use a lot of CPU?

Encoding video is a very CPU-intensive operation, and OBS is no exception. OBS uses the best open source video encoding library available, x264, to encode video, and can use hardware encoders like NVENC on high end GPUs.

Is it better to stream with GPU or CPU?

If you have a powerful GPU, GPU encoding is better. If you have a powerful CPU, CPU encoding is better. The recommended number of cores for streaming is 6 so if you have 6 cores you can easily stream your game play. If you have the new Nvidia Turing cards I will suggest you use GPU encoding.

Does streaming use a lot of CPU?

So, streaming puts heavy strain on the CPU part of it, therefore depending on what kind of encoding u choose, it will use more or less CPU time for encoding task. If u put too much of your CPU into encoding task, it will fall behind in supplying your GPU with enough data for 3D processing of the game your playing.
