Fog Bug

| I Have a big problem, Ive noticed that my laptop has an issue with hardware fog. My desktop with a gforce4 works fine. The laptop has an Intel 82815 graphics. I wouldnt really care except this is a very standard card with on board graphics M/Bs. Is this a blitz problem or an intel problem?? The problem is, is that the fog depth seems to be more on the horizontal faces than the vertical faces, and it causes a flickering mess near to the camera. If I use a large initial range its ok, but I need the range of 300 to 500. |

| I think that its not so much a problem as a feature which Intel don't support - I may be wrong, but I my laptop has problems with Alpha channels when I ask too much of it. Laptops eh? who'd have 'em!? IPete2. |
| ||
| I get slowdown with too much alpha as well ONBOARD GRAPHICS REALLY SUCK! |
| ||
| intel are notorious for bad 3d video support. So there's no surprise there, one of the cursed banes of indie game dev lol. |
| ||
| Fog screws up on my ATI based laptop as well.. has with every interation of Blitz and every iteration of laptop with ATI that i have had. Tracer |

| Laptops with old "integrated 3D video" stuff are from hell. You can't expect them to work with any games or Blitz... new ones are bit better, but laptops are what they are... not meant for 3D stuff really. |
| ||
| Its not just the laptop, the 82815 is on a lot of combi desktop motherboards. A friend of mine has one and i think his board is an asrock, another common name. I have fixed the problem with a menu option for fog fix. Which disables fog on the infinite plane which is the water. |

| Older ATI cards don't support the particular type of DirectX fog Blitz 3D uses -- they told me themselves (I forget whether it's Table Fog or Vertex Fog). |
| ||
| I have the accursed onboard graphics and alpha is totally messed up, but at least we can use them to test what a lot of people are going to experience. |
| ||
| they probably don't support table fog - it's the more computationally expensive (and better-looking) of the two. |
| ||
| Ive never had any problems with fog and intel 8281x cards... theyre just old and slow.. slightly slower than a TNT2 in fact :/ |
