d3d_texlimit

d3d_texlimit

At game start this variable gives the maximum texture size the 3D card can display. On most 3D cards this is 2048 or 4096. Old 3D cards have a maximum texture size of 1024. All textures will be automatically 'shrunk' to the size given by this variable.

Range:

8 .. 4096

Type:

var

Remarks:

For allowing huge levels to run smoothly on system with very limited texture memory, d3d_texlimit can be set manually to a lower value. For instance after setting it at 128, all textures that are bigger than 128x128 will be reduced in size upon loading, but the smaller ones keep their original quality. This way when setting if before level loading, the overall texture memory needed for a level can be reduced by over 50%.
When setting this variable to a low value, take care about all functions that rely on texture size (f.i. writing into bitmaps by pixel functions). Exceeding the texture size on writing leads to a crash error message.

Example (lite-C):

function main()
{
   d3d_texlimit = 256; // enforce 256 pixels max texture size 
   ...
