NVIDIA CSM Demo on Quadro FX 4500?

OpenGL OpenGL: Basic Coding

I downloaded the Cascaded Shadow Maps demo and source from the NVIDIA SDK 10 website. It wouldn’t run on my Quadro FX 4500 (latest driver installed 182.65).

When I dug into the source to find the problem in a debugger my Quadro FX 4500 is reporting that EXT_texture_array isn’t a supported OpenGL extension. Is that right? Texture arrays aren’t supported on a high end NVIDIA card? That can’t be right.

If that is right, does anyone have a pointer to a CSM demo with source that doesn’t use texture arrays?

Thanks,
Robo

Quadro FX 4500 is based on a G70, which was introduced around 2005. There have been 3 core generations since then (G80,G90,GT200).
