Essentially, ping lag is the result of a bad connection between one or more of three components which make up the typical Tanki Online setup. They are:
1. The Client (Player using browser or flash player)
2. The Server (the hardware location that houses the software of the game- e.g, map data, weapon, hull, and paint data, server chat lobby, etc.)
3. Other Clients
"Lag", as it is referred to across much of the Internet, is the term given to discontinuities between servers and their data's destination, or shortages of data being supplied in a required time frame. In this game, lags are manifested in two occurrences, them being disconnections from the server, occasionally in the form of an automatic server-issued ejection from a battle (known as a 'foul play detected' message), and unrealistic tank actions, such as running into walls,spinning in circles for minutes at a time, and sporadic 'jumping' from one place to another (sometimes mistaken for attempts at hacking).
An easy way to determine if you have Ping lag is by looking at the counter in the bottom right corner of the screen. If the 'Ping' number is red, it means your internet connection isn't very stable. A higher ping indicates a worse connection, as it means there is a longer connection delay between the client and the server.
FPS (frames-per-second) lag is different to Ping lag. The measure of frames-per-second indicates the frame rate which is visible while you are playing Tanki Online. Depending on your FPS, the game will either appear to run smoothly, or slowly with delayed/disjointed graphics. This is often the result of a lack of RAM or graphics processing power available to your computer. FPS lag is caused by a number of things:
1. Too many graphics settings are enabled.
2. You have too many programs open simultaneously.
3. Your computer doesn't have enough RAM (Random-access Memory).
4. Your computer has an inadequate graphics processing unit (GPU).
An easy way to determine if you have FPS lag is by looking at the counter in the bottom right corner of the screen. If the 'FPS' number is red, it means you have FPS lag. A higher FPS count will result in smoother, more responsive graphics.
If experiencing lag, players should refer to the How to reduce lag Wiki page.
