    9697The lobby is hosted by us, but all the games you play connect you directly to the game's host. Depending on your location and internet quality, you may experience a high Ping/ latency with certain players. You can check your RTT (also known as Ping) with different hosts by pressing `F11 or Alt+F11` and toggle through until you see the `Network statistics` panel.

    103105__Computation lag:__[[BR]]
    104 Yes, this is a common problem with the game. It will lag on most machines it is actually CPU bound, not your GPU. Try playing on smaller maps and limit the population to 600-800 units on the entire map.[[BR]]Rendering, simulation (e.g. gathering / attacking) and pathfinder all contribute to the lag.  If you have more units, more things need to be drawn which affects rendering, more things to calculate for unit activity affects simulation, and larger map sizes cause longer paths which affects the pathfinder.
     106Yes, this is a common problem with the game. The main factors that determine how smoothly 0 A.D. runs are primarily the CPU speed (since the game is not yet multi-threaded), the amount of available RAM, the type of graphics card in your computer, the game options and the game's setup settings you choose. If you are unhappy with the game's performance on your computer, there are some things you can do to improve it:
     1071. ''Before Launching 0 A.D.''
     108 - Close all other applications: It is highly recommended to close all other applications as they consume resources and affect the overall performance of the system.
     1092. ''Game Options''
     110 - Enable `Prefer GLSL`
     111 - Enable `FXAA` (no performance impact) or  `MSAA` (disable for very weak GPUs)
     112 - Set Models to the lowest values
     113 - Disable `Shadows` or set the `Cutoff distance` to a low value.
     114 - Enable `Water Effects`, but disable other water effects (reflection, refractions)
     1153. ''Game Setup''
     116 - Play on smaller maps and limit population to 600 units across the map for all players. Rendering, simulation (e.g. gathering / attacking), and the pathfinder all have an impact on performance.  If you have more units, more things need to be drawn, which affects rendering, more things to calculate for unit activity affects simulation, and larger map sizes cause longer paths, which affects the pathfinder.

    106119  **NOTE:** Multiplayer games are calculated on all computers simultaneously, with the slowest PC determining the game speed. If your computer is a bit outdated, you should reduce the graphics settings to a minimum. This might make the game faster for everyone.

    116129(1) Every frame that is calculated by the GPU is "prepared" by the CPU, one of them will limit your frame rate (FPS). When you select graphics effects, you create additional workloads for your GPU and CPU, causing your framerate to drop. Current PCs are mostly CPU limited in 0 A.D. because the game is not yet multi-threaded. That means they usually only use 1 core. Since graphics effects mostly affect the GPU, you can (on newer PCs) choose the higher graphics effects without sacrificing performance. [[BR]](2) Heating up the hardware leads to thermal throttling of the hardware. This effect is especially known for mobile PCs. If the hardware gets too hot, it throttles its performance until the hardware cools down again. Therefore, a limited but constant frame rate is usually better than a frame rate that fluctuates due to thermal throttling. [[BR]](3) VSync will also limit the framerate to the framerate of the monitor (I estimate 60 frames/Herz).[[BR]]

    125 A way to ease the load on the PC/laptop is: [[BR]](1) Host a game, but let the host PC/laptop be a spectator. [[BR]](2) When the match starts, turn all graphics settings on the PC/laptop to a minimum, then choose one of the player's perspective. The idea is that normal observer/overload perspective allows you to see every detail on the map, which increases load. If you switch to a player's perspective, the PC/laptop only needs rendering what that player can see. This would only require the PC/laptop to render a small portion of the map, hence the load is smaller. Even better: Add an unassigned player and switch to that perspective. The unassigned player will never explore or expand, so its field of view would be limited to just the starting civic centre. [[BR]]
