Tip: Howto improve speed of MB
« on: March 15, 2003, 09:12:03 pm »
If you have a video card with 64 or 128 meg video ram then there is a way to improve speed (and also lag) when running MB.

First tip is of course to upgrade to the 007 release. If you can\'t use the updater then check http://www.planeshift.it for more info about that.

But there is another thing you can do. In c:\\Program Files\\PlaneShift\\data\\config\\opengl.cfg you will find the following four lines:

Video.OpenGL.SuperLightMapNum0 = 12
Video.OpenGL.SuperLightMapNum1 = 148
Video.OpenGL.SuperLightMapNum2 = 48
Video.OpenGL.SuperLightMapNum3 = 0

If you have 128M ram on your video card (NOT main memory. I\'m talking about video card memory) you can change these values to:

Video.OpenGL.SuperLightMapNum0 = 15
Video.OpenGL.SuperLightMapNum1 = 185
Video.OpenGL.SuperLightMapNum2 = 60
Video.OpenGL.SuperLightMapNum3 = 0

This will enable MB to use more video memory on the card for textures and it will improve speed. If your card only has 64M RAM then those values may perhaps be too much and decrease speed again. You\'ll have to experiment but if it is not optimal you might try something like 14,160,55,0 for example.

A very short summary: the first number is the number of 128x128 textures used for lightmaps. The second number is the number of 64x64 textures and so on. Every pixel of a texture takes 4 bytes memory so you can calculate yourselves to how much memory that corresponds. Also keep in mind that the video card memory is also used for other things. Don\'t use it all up. I recommend using perhaps half of it for this.

Well like I said. Edit the opengl.cfg file and change the values like I explained in my message above.

Nice tip Jorrit thanks, I\'ll try it next time I\'m on.

Huh? He just explained it step by step in his post. You have to open the file \'opengl.cfg\' in Notepad or other text editor and then make the changes he suggested - does that help?

is it worth it at all to try and tweak that file on a 32 mb video card... i know you said 64 or 128, but could i improve at all? or should i just leave well enough alone?

I assume by him talking about tweaks for 64mb and 128 mb means that it is already tweaked out for a 32mb card. Speaking that the majority of the population is still using 32mb.

MB = Molecular Blue

Which is the game that this forum was made for... How did you get to the forum if you aren\'t here from the game page? Just curious.

What isn\'t remembered, never happened.

Memory is merely a record...
you just need to rewrite that record.

My gfx card is a Geforce 2 mx/mx400 and thats 32 MB, can I still use those same values to tweak the card? Sorry if the answer is wrapped up in here somewhere, I am a bit out of it.
