Doesn't work at all

[mizipzor]

Seems to be a problem relating to exporting the world after generation. Pressed "p" and got this:



Not important, maybe not even related to d18 but I just wanted to have it reported somewhere.

[Baughn]

It's a d18 bug - look, I even acknowledged it - but it's not high up on my list.

I'm going to rework the entire map-export pipeline to be renderer-agnostic; there's no reason it needs to touch the renderer at all. But that's later.

[CobaltKobold]

...but it needs to render the map to put it in file, even if it need not display it. I'd guess how it does it now is display the map screen by screen and composite the shots. The display step is unnecessary, but useful for errorchecking.
(Hey, text map export? oh, wait, colors.)

[Baughn]

To be exact, I'd use the existing 2D renderer (after fixing the colors), but make its screen surface a parameter instead of always using the display. That'll work regardless of rendering method.

Oh, and a question for you folks:

I want to use texture buffer objects for shader mode. It gives me a *dramatic* performance increase. However, that's technically an opengl 3.2 feature, and though my 8600M supports them just fine, I'm unsure how many older cards (that aren't too old to support shader mode at all) would.

So, if you want to have a say in that, visit (and download and run) http://www.realtech-vr.com/glview/ then tell me if ARB_texture_buffer_object appears on the list of supported extensions.

If you're on linux, just use "glxinfo | grep texture_buffer_object", no glview needed.

My GF 9800 GT does support ARB_texture_buffer_object, but my GF 7900 GS does not. I'm guessing it's only the GeForce 8 series and later that has it, with a good chance it generally being stuff marketed as DirectX 10-supporting that has it.

[Malicus]

GF 9400 GT, ARB_texture_buffer_object appears in the list.

[Xgamer4]

My Geforce 9800GTX+ has support for ARB_texture_buffer_object. I don't think that comes as a surprise to anyone, though.

[shadow_slicer]

My GF 8500 GT has support for ARB_texture_buffer_object.

[Baughn]

So basically, 8000-series cards and equivalent support it, older don't?

I think I can live with that. It's such a humongous speed boost, and using shaders like that on older cards probably wouldn't work too well anyway.

I tried to load a save file from 40d16 and it crashed. Anyone know why?

[Shadowlord]

My ATI x800 GTO appears to support no OpenGL 3.2 features at all (or GL_ARB_texture_buffer_object, which OpenGL Extensions Viewer says is from OpenGL 3.1), and doesn't support shader language version 1.3.

It has 100% of OpenGL 2.1 features.

[Footkerchief]

I tried to load a save file from 40d16 and it crashed. Anyone know why?

Was there any error message?  Can you load that save in vanilla 40d16?

[Yaddy1]

Well in 40d16 AND in 40d18 it gave this message 'GPU does not support non-power-of-two textures, using 512x512 catalog.' Also if you mean do I have any mods the answer is apart from some new trainable animals no.

Did a bit of testing with how the game feels rather than hard numbers in d18. I found that the fps while being lower is a bit more stable. In d17 I would start out with a constant 100 fps then as I got to the point of having 100 dwarves it would drop to 20-30. In D18 I start with 40-50 fps then as it expands it drops by about 10 hovering near 30-40 fps. I have yet to get another 100 fps fort in d18 but I'll let you know when I do and tell ya how it goes.

[RandomNumberGenerator]

So... how do I change the grid size?
