Google held its E3 2019 Stadia presentation on June 6th. During its press conference and Stadia Connect live stream, Google announced which games will be coming to the streaming service. Google also shed light on what kind of performance users can expect from Stadia while streaming games over their internet connection. Stadia running at 720p at 60 FPS or 4K HDR at 60 FPS with surround sound, all depends on your internet connection.
According to the performance specifics given by Google’s Vice President Phil Harrison, Stadia will be able to stream games at resolutions ranging from 720p to full 4K with HDR at a stable 60 FPS rate.
However, the resolution and frame rate that you’ll get will heavily depend on your internet connection bandwidth. Which means Stadia’s performance depends on your internet connection. The thing to understand here is that you’re not streaming data one way like how it works with YouTube or Netflix, data is being transferred both ways. Your device will be sending out controller input constantly. This input will include things like moving your character around in the world and voice chat. On the other hand, you’ll also be receiving data at the same time from Google’s data centers.
This means your internet connection will be used to send and receive data in the same pipeline. Think of your bandwidth like a pipeline. The wider the pipeline is, the more easily data will go through it. The narrower (smaller) the pipeline is, the more difficult it will have in order to push data through it.
The minimum recommended bandwidth by Google is 10 MBPS for Stadia.
According to Phil Harrison, if you have an internet connection anywhere from 5 MBPS to 15 MBPS, you will be able to stream games in 720p HD resolution at 60 FPS with stereo sound on Google Stadia. This is excellent for smaller devices such as tablets and phones. Most low-end phones have 720p displays anyway. Stereo sound means there are two channels: Left and Right. This works best for headphones or a set of two speakers.
If you have a higher bandwidth connection, say anywhere from 15 MBPS to 25 MBPS, you will be able to stream games at 1080p resolution at 60 FPS with HDR and 5.1 surround sound. This particularly works well with home theatre systems.
If you have a proper fiber internet connection with bandwidth anywhere from 25 MBPS to 35 MBPS, you will be able to stream Stadia games at 4K resolution with HDR at 60 FPS and 5.1 surround sound. This is excellent for 4K displays that support HDR and a speaker system with 5.1 channels.
It is likely players will have access to resolution and frame rate options within Stadia. So if someone wants to favor resolution over frame rate, vice versa, they will be able to do so using Stadia’s options. If Stadia’s performance on your internet connection is low, then, in theory, you can lower either frame rate or resolution to see a boost in the other.
Harrison has said:
With Stadia, our goal is to make gaming more accessible for everyone
When Stadia launches, users will be able to play Stadia games their your TVs (via Chromecast Ultra), desktops, laptops and tablets (via Google Chrome) and on smartphones (via Stadia app)
Google also revealed about 30 games which will be available for Stadia. Stadia will launch in November 2019 in 14 countries. Google will then expand Stadia to these countries in 2020: US, Canada, UK, Ireland, France, Germany, Italy, Spain, Netherlands, Belgium, Denmark, Sweden, Norway, and Finland.
