[Gvsig_english] gvSIG 3D: hardware requirement

[Jordi Torres]

Hi Silvio,

1. What is the minimal and, most of all, the best requirement about the Cpu?

The minimal requirements are Pentium IV / 512 MB RAM / GraphicCard
compatible with OpenGL 1.5.

It is recommended Pentium IV or newer/ RAM>= 1 GB / GraphicCard compatible
with OpenGL 2.0 and 256 MB or more memory.

More precisely, which one is the best Cpu to run it, a 32 or 64 bit?

About 32 or 64 bits, native libraries for the whole gvSIG are compiled only
for 32 bits, so working in 64 bits could result in unexpected errors. You
can work via emulating 32 bits in a 64 bits machine.

2. How about the graphic card and the RAM Gb memory?

It is recommended to use a 256 Mb or more Graphicscard.

Yes, but the most important thing is the graphics card you have.
Nevertheless we tested 3D extension in a nettop with an gfx intel onboard
chip and it worked, with limitations.

Of course, it should be. But remember to get the latests drivers for your
hardware, it is very important!

I guess it is, but  we have not do any benchmarking. BTW graphics card
drivers are important, for example ATI gives better driver support for
windows than for linux, and it reduces performance.
