TopoFusion 3D works fine on my Windows XP machine with a single monitor. On my Windows 98SE machine with two monitors driven by a Matrox G450 in the DualHead MultiDisplay mode, the system crashes with the message:
Max texture size=1024X1024, 2048X1024 needed
The system freezes, requiring use of the power switch.

I don't work for TopoFusion, but I'm curious what version of DirectX you have on your Windows 98SE box? And are you running the latest Matrox drivers?

3D does work on some multi-monitor systems -- mine, for example (nvidia card).

The texture size deal is a problem, but it shouldn't crash the system, just switch to software mode. If you set your system to single monitor does the 3D work?

It could also be a video driver issue, so I'd update as suggested above.

Kuren and Krein,

Thanks for the comments. My Windows 98se system was assembled 5 years ago and has been updated only as needed. My Matrox driver is ver 4.12.01.1800 of 2/23/01. The latest version is dated 2/27/02. My DirectX version is 3 years old.

I will update them next month after completion of a scientific paper which is requiring intensive use of graphics on this system.

I use dual monitors, but I use dual video cards, different chipsets..

I get that error message if I have the resolution set too low, or the color bit depth is dropped.. I forget wich.

The only problem I've encountered is if I fire up TF on one monitor, thgen move it to the other.

Now you got me wondering what would happen if I stretch the window over both screens? If we had the 3-d playback going that would be truly kewl.
