In some cases you might be able to push to a higher quality than the test reports, but could potentially run into trouble if your Internet connection is not reliable.įor more technically inclined users, the streaming tests is testing performance with both TCP traffic and UDP traffic. The results are conservative to leave some extra upload bandwidth available in case of performance variations and to allow bandwidth for other apps you might need while streaming. Instead, it attempts to send fixed rate, consistent traffic, similar to a video stream, and looks at performance variations and packet loss to judge how consistent your Internet performance is at a specific speed. Unlike a speedtest, the streaming test is not attempting to completely max out your upload speed. At the end, the test will report the resolution and frame rate (fps) your Internet can support. The Livestreaming test evaluates your upload performance with Speedify to estimate what video streaming quality you can consistently expect to support. Updated for new Twitch API which requires client_id.Īdd 'Share' button which uploads a screenshot of the results to imgur.With Speedify 11.5 we introduced a Livestreaming test in the Speedify app along with the existing Speed test.

Internet speed test for streaming drivers#

Show interface name and driver version on the main window.Ĭheck for known buggy 3rd party drivers and warn user if found. Updated quick select for new Twitch server names.Īdded individual server check boxes for testing specific servers.Īdded data sharing (see privacy notice above). Updated to use Twitch ingests API instead of the discontinued Kraken API.

TwitchTest is open source, licensed under the GPLv2. The program will prompt to launch as an administrator since connection quality statistics can only be measured under admin mode. The Visual Studio 2015 Runtime (vc_) is required (you'll get a missing VCRUNTIME140.DLL error otherwise). TwitchTest will work on all modern versions of Windows. If you wish to opt out of this data collection, pass -disable-data-upload on the command line when starting TwitchTest. Data is sent securely over HTTPS and will only be made available in anonymized, aggregate form, eg to show how a certain ISP compares relative to others. Privacy NoticeĪs of version 1.4, TwitchTest sends your settings and results to my server for analysis. Testing can take a long time, so it's best to select only regions close to you. You must not already be streaming during the test, and although TwitchTest needs your stream key, your stream will not go live. Streaming at your absolute maximum bitrate will result in lag and possible dropped frames. When setting the bitrate in your streaming program, you'll want to leave around 500kbps spare for any games and other data that may need to be sent. Some ISPs may also have poor routing or overloaded peering with Twitch which affects your maximum possible upload speed. Note that speed test sites will not give you an accurate view of your potential upload speed to Twitch, as they are designed to measure your upload as a whole, not to a single site over a single connection.

You probably shouldn't change this unless you really know what you're doing! Other programs may use the system default. The default of 64k matches what OBS Studio uses. The TCP Window setting allows you to experiment with fine tuning certain TCP parameters. Servers further away from you will have a higher RTT. RTT: This is the time it took to establish the connection (Round Trip Time). If your internet connection is below 10mbps upload, quality numbers may be lower due to your ISP discarding data. It's measured out of 100, and a quality rating of 80 or higher is recommended for a stable stream. Quality: This is a metric which tries to measure the overall stability / quality of the connection based on the rate at which data was sent and the number of re-transmitted packets.

Note that TwitchTest will never go above 10mbps during testing and Twitch currently recommend a maximum of 6mbps (6000 kbps) when streaming. Here's what the different numbers mean:īandwidth: Fairly self explanatory - this is the bandwidth TwitchTest was able to sustain to the server. Picking a server with sufficient bandwidth, low RTT and a high quality rating will ensure the best results when streaming to Twitch.Ī screenshot of the program. TwitchTest is a free, open source program that allows you to easily measure your upload speed to each Twitch server.
