Online Gaming: Playability Score
|
||||||||||||||||||||||
The OPScore, or Online Playability Score, is a benchmark that measures game lag under network stress; therefore, the OPScore tool is a good way to measure the quality of your network for online gaming. The OPScore test can be run from any Windows PC with an Internet connection.
The OPScore test includes two parts:
- The first part, the Internet Connection OPScore, measures game lag without any background data transfers to load the network. This tests the quality of your Internet connection itself.
- The second part, Quality of Service (QoS) OPScore, measures the ability of the network to prevent game lag even when there is other traffic present on the network. The tool uses background data transfers to load the network during the QoS OPScore stage of the test.
To test your network, click on the Start OPScore Test button above.
Network Gaming Quality Test
1. What do the results mean?
Internet Gaming Quality: The first phase of the test measures how well your internet connection can support gaming. This test is done with no background traffic on the network, so the test results depend only on the quality of your internet connection and your distance from the test server. The results are given on a 1 through 5 scale based on Online Playability Score, or OPScore.

2. What is OPScore?
OPScore, or Online Playability Score, describes the perceived network quality for online gaming. The OPScore is a benchmark that measures game lag under network stress; therefore, the OPScore tool is a good way to measure the quality of your network for online gaming. The tool measures the amount of time it takes data to travel from the home computer to the test server and if any packets have been lost along the way.
| OPScore value | User Satisfaction |
| 4.34-4.5 | Best |
| 4.03-4.34 | High |
| 3.60-4.03 | Medium |
| 3.10-3.60 | Low |
| 2.58-3.10 | Poor |
| 1.0-2.58 | Not Recommended |

3. How is OPSCore Calculated?
The gaming quality test measures the condition of your network under these conditions. This model uses measurements of delay, jitter, and packet loss on the network to predict network quality.

4. How do I set up my router and PC for the test?
Routers that feature StreamEngine technology are already designed to identify and prioritize network traffic without configuration. StreamEngine will also treat background traffic, such as that used in the test, with a low priority. This detection process is not port based. However, most QoS engines use a port-based prioritization scheme. The test uses different ports for specific traffic types. If your home router does not use StreamEngine, you should configure the following priority levels.
