Default Re: X-Plane obj files crash AC3D

Oh, I misread your system specs.
I was thinking '1024 MBytes Type GDDR3' is your RAM :roll:

Considering that:
  • I'm using a Macbook Pro ( 8GB RAM and a 512MB nVidia GT300M )
  • I just opened a 26 MB ac3d file.
  • Total objects: 1150 surfaces: 238635 vertices: 200745
  • It uses 9 texture png's which use around 40 MB VRAM (uncompressed)
  • I used to work on this model on my old Macbook Pro (core2duo 2.4GHz) with 4GB/256VRAM without any issues as well.

...your model is certainly not even close to ac3d's limitations on your hardware.

At least on Mac AC3D will only address 4GB anyway (32bit app).
8GB do help to get the OS and other apps out of the way though

Have you tried updating graphics drivers?
Reducing some rendering options (anti-aliasing, et al)?

Maybe someone with better WinXP skills knows more.
