Slightly Off Topic - Graphics Card - SeeYou 3D

OK, A couple years ago I upgraded to a Dell XPS 400. I thought I was
getting a reasonably good graphics card when I ordered.

RADEON X600 256MB is what is listed under Display adapters.

Under that are two lines
RADEON X600 256MB HyperMemory
RADEON X600 256MB HyperMemory Secondary

My "old" computer ran the 3D playback of a flight log just fine. My
"new" computer shows "No 3D graphics available"

I sent an e-mail to SeeYou and their response was to reduce the hardware
acceleration. I did so and then the 3D graphics started working, but it
didn't seem like the performance was good.

Anyone more knowledgeable about graphics card settings or new graphics
card recommendations care to offer some suggestions.

I was going to swap graphics cards between the old and new computers,
but the graphics card sockets are different so they are not interchangeable.

Thanks,

Gary
