Hi Silvio, <br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
1. What is the minimal and, most of all, the best requirement about the Cpu?<br></blockquote><div><br><p style="margin: 0pt;">The minimal requirements are Pentium IV / 512 MB RAM / GraphicCard compatible with OpenGL 1.5.</p>
<p style="margin: 0pt;">It is recommended Pentium IV or newer/ RAM>= 1 GB / GraphicCard compatible with OpenGL 2.0 and 256 MB or more memory. <br></p><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
More precisely, which one is the best Cpu to run it, a 32 or 64 bit?<br>
I suppose a 64 bit Cpu but, maybe, I am wrong.<br>
I don't know anything about Java :-)<br></blockquote><div><br>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.<br>
<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">2. How about the graphic card and the RAM Gb memory?<br>
</blockquote><div> <br>It is recommended to use a 256 Mb or more Graphicscard. <br></div><div><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
On the whole, I suppose, the more powerful is your computer, the more faster the 3D extension should be.<br>
Unfortunately, this means a more expensive computer to buy, in the end :-)<br>
<br></blockquote><div><br>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. <br>
<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
To sum up, let's suppose a gvSIG user decide to buy a new computer.<br>
In Italy, right now, the "standard" Pc would be, for him, something like that:<br>
"Windows 7" Premium edition, 64 bit Cpu, 4 Gb Ddr 2 (or Ddr3), 512 Mb Ram.<br>
Is this standard configuration fast enough for working with the 3D extension?<br></blockquote><div><br>Of course, it should be. But remember to get the latests drivers for your hardware, it is very important! <br> </div>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
For example, about speed, I might be wrong, but I suppose it would be more proficient to use a Linux configuration (e.g. no Anti-virus always running and so on).<br>
I suppose, on Linux (e.g. Ubuntu 64 bit), with the same hardware, the 3D extension is faster?<br>
<br></blockquote><div> <br>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. <br>
<br>Greetz, <br><br>Jordi<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Best regards,<br>
