Game streaming has become popular where gamers can build a community of fanbase to share their gameplay with on different platforms. Thanks to NVIDIAs constant improvement with NVENC, streaming has been made so much easier using NVIDIA hardware that is packed on MSI Gaming laptops. 

With that, NVIDIA has a guide on how to set up your live stream and how to get started with game streaming using Open Broadcaster Software.
The objective of this guide is to help you understand how to use the NVIDIA encoder, NvEnc, in OBS. We have simplified some of the concepts to make this accessible to a wider audience. If you think we can improve any part of this guide or find any issues or mistakes, please post below and we will be happy to update it.

BITRATE, RESOLUTION AND FRAMERATE

Encoding is all about compressing images. The smaller the size of the image, the less we must compress it and the more quality it keeps. While the same applies for framerate, a viewer can really notice a drop in FPS but not so much in resolution, so we will always try to stream at 60 FPS.

First, run a speed test to determine your upload speed (e.g. Speed Test). We want to use around 75% of your upload speed, as the game and other programs such as Discord will also fight for bandwidth.

Then, we will determine the resolution and FPS that we can use for such bitrate. Most streaming sites have recommendations (Twitch, Mixer,Youtube) on what to use. 

You can refer to this for upload speed:

RECOMMENDED SETTINGS

These are our recommended settings for OBS Studio 23.0 and up. Youll want to test and adjust these settings using a private account where you can verify youre happy with the results.

VIDEO TAB SETTINGS

Base (Canvas) Resolution: Set the resolution you normally play at. That is, your desktop resolution (if you play in borderless mode), or the game resolution you normally enter (if you play in full screen).
Output (Scaled) Resolution: Enter the resolution appropriate for your Upload Speed and Bitrate, as we discussed in the previous section.
Downscale Filter: This allows you to select a downscale filter that will provide a small image sharpness enhancement, at the cost of some encoder workload. NvEnc is very efficient and typically runs at low utilization, so we recommend using this with the Lanczos, 32 samples option for the best quality.

FPS: Enter the FPS appropriate for your Upload Speed and Bitrate, as we discussed in the previous section.


OUTPUT TAB SETTINGS




For an easy, out of the box configuration, then do the following:

Output Mode: Simple

Streaming:

Bitrate: Enter the Bitrate appropriate for your Upload Speed, as we discussed in the previous section.

Encoder: Select Hardware NVIDIA NVENC (new).

Enable Advanced Encoder Settings: Checked. This makes the next option visible.

Encoder Preset: Max Quality. If you are streaming 4K resolution on an RTX 20-Series, you will want to reduce this to Quality, as the RTX cards already run image optimizations that previous generations do not.


Recording:

Recording Path: This is the directory where the videos will be saved. Make sure the hard drive you select has enough space!

Recording Quality: High Quality typically works for most users, but you can change this to Indistinguishable Quality if you have enough disk space or are going to do short videos (about 60 seconds).

Recording Format: FLV or MKV.

Encoder: Hardware (NVIDIA NVENC).
