What to do if Planet is slow


Right-click on the floor and select the menu TOOLS > GRAPHICS


"frames/sec" indicates how many frames per second are displayed. A value below 30 indicates you're lagging. The first thing to do then is to check the option "compute avatars in graphics card" to see if the value increases. On some older graphics cards this can however display weird triangles instead of the avatars, if this is the case do not check this option.

Here the other options:

"frames/sec" indicates how many frames per second are displayed. This value is limited to 60 because your screen can't display more anyway. By checking the 'unlimited' box you can measure how much your PC could display without this limitation.

"max draw distance" indicates how far you can see, in meters. By default 1024 m. If the display is too slow you can decrease this value.

"max lights" indicates the maximum number of lights displayed. Some graphic cards slow down the display significantly at night when many lights are on, in that case decrease the value to display only the lights near you.

"active particles" indicates how many particles (snow, smoke) are displayed at most. If the display is too slow you can try to decrease this value.

"texture memory" indicates how much memory the graphics card uses to store textures. If this value increases beyond 600, 700 or 800 Mbytes your PC may slow down or DirectX may give an error. Then reduce the "max lod" value to 11, 10 or 9, which will reduce the memory consumption but can make some textures a little blurry. "Max Lod" indicates the maximum size of the textures stored in the graphics card. For example, a texture of LOD 12 has a size of 4096 x 4096 pixels (2^12 = 4096) and consumes 64 Mbytes.

"compute avatars in graphics card" should be checked as this increases the number of images per second. On some older graphics cards this can however display weird triangles instead of avatars, if this is the case do not check this option.

"sort transparent textures" should always be checked otherwise transparent textures are not displayed properly.

"support shiny textures" should be checked to display the reflections.

You can check "defragment cache" from time to time if you have a non-SSD hard disk. The next time you start Planet, the large cache file on your hard disk will then be defragmented (it will take 5 min) which will speed up the display. This has no effect if you have an SSD hard disk, so electronic.

The "Reset to defaults" button resets default values that are normally suitable for everyone.
