I was now testing our code on a different machine: Asus P5AB Mainboard, AMD K6-2 500, 192 Mb Ram, Voodoo 3 3000 AGP (I had to saw off a part of the CPU cooler in order to put in the card) with latest available drivers.
The problem: If I´m in 32 bit depth mode, I cannot start the prog, DB Pro compilat means that this is not supported by Hardware: "Runtime Error 1507 - Display using 32 bit is not supported by available hardware at line 0".
Other problem: I grab a image sized 51,449 pixels, if I put it on screen again, it is well on GeForce 2 MX card, but not well with Voodoo 3: The image looks like it was halved verticaly and then stretched verticaly again, every second pixel was doubled and replaced other pixels. This does not happen if I get smaller images (51,100), so I have a workaround.

I had that problem when trying to use DB Pro apps on 16 bit gfx cards. Even when the first line of my prog was to set the display mode to 640x480x16 is still gave me the same "32 bits not supported" error.

I dunno what's up with that image corruption though.

Voodoo has a maximum image size, if you where to use a voodoo 2 card that limit is 256x256... Although it was ground breaking in it's day, I think it's time to put old Voodoo cards to rest

As for the 32 bit display error, i'm running a voodoo 3 system here and I have no problems with runtimes starting, try setting your windows display to 16bit and using 'Windowed - Full Screen' mode. Or at least select a default resolution that is 16 bit in the project display settings.

I agree with PneumaticDryll, Voodoo cards have had thier day now also seeing as there is no 'official' driver support I cant see any way to continue to support them either.

I hear through the grapvine that M$ will be dropping some of the 3dfx cards from new revisions of Direct X until they are no longer supported. Knowing M$ this means they will not be in the next release of DX.

If the screen resolution is set to 16 bit doesn't mean the texture resolution is set to 16 bit. If the image is 32 (or 24) bit and the resolution is in 16 bit there won't be any real difference.

Our Program is designed to run in Windowed mode, any other mode is nonsense for this application, but we reduced the image size to less than 256x256, and divided larger images into smaller ones.
As I said before, we are just testing this with older configurations to ensure that the application will work with them correctly. And the graphic card used earlier in this system, was a ATI Rage IIC with 4 Mb, enough to drive a 15" TFT monitor, and enough for a web server, less hot than any modern graphic card, and so able to work non stop 24 hours a day with minimal cooling and noise.
If I recall it right, the minimal requirements to run DB Pro programs was a 8 Mb accelerated graphic card, Voodoo 3 has 16 Mb! The same program in a earlier version (DarkBasic 1.xx) was even running on a notebook with only 1 Mb Video RAM. And it does not need to use any 3D functions, so I wonder why DB Pro has no switch to use such old graphic cards if the code does not need any 3D functions.

Minimum requirements is an 8meg DirectX compatible video card. Considering DX8 was not even a twinkle in Microsofts eye when the Voodoo came out (and the fact they've not updated their drivers in a LONG time) will lead heavily towards a "if it runs, it's more out of luck than anything" result I'm afraid. I had a Voodoo3 and it was hopeless for development in DBV1, let alone Pro (this was before I joined DBS) - I upgraded to a GeForce and all my problems went away. I don't think DB ever liked Voodoo's very much unfortunately

Cheers,

Rich
