ah ok, in questo senso il tuo disscroo non fa una piega. Secondo me il fatto e8 che essendo prodotti Microsoft, c'e8 il grosso problema delle licenze e dello sviluppo di codice chiuso, basta vedere l'ennesimo macello che ha provato a tirar su la Microsoft. Purtroppo anche gli sviluppatori fanno quello che possono. Anche il progetto Mono ora e8 al centro di un ciclone, in coppia con il progetto Microsoft-NOvell. Alla fine la realte0 e8 che se usi Linux dovresti utilizzare software libero e non per Windows, altrimenti tanto vale restare su Win. Ad esempio, io Wine ho rinunciato ad utilizzarlo per i troppi casini che bisogna fare per far funzionare un programma, che a volte si rivelano inutili.Tuttavia apprezzo il progetto anche perche8 per molti funziona, anche qui dipende dai casi.Fa comunque piacere che ci sia gente competente che legge questo blog Ciao!

If you plan to run Wine, you may need to tell fglrx to not corrupt the fs register.
To do this, add the line:
<pre>
Option "UseFastTLS" "2"
</pre>
to the "Device" section in ''/etc/X11/xorg.conf''.  This supposedly causes about a 10% hit in opengl benchmark scores, but at least things don't crash.  See also http://wiki.winehq.org/fglrx and http://www2.ati.com/drivers/firegl/readme0325.txt
 
This issue has since been fixed in Wine. However, some native Linux games ported toolkits branched from older versions of Winelib, such as Cider, are still sensitive to this bug.

The fglrx driver is not known for its speedy 2D or 3D performance, but there are ways to improve it.

2D

If you suffer from slow 2D speed it might help to set 

Option		"XaaNoOffscreenPixmaps"                "true"

in the fglrx device section of /etc/X11/xorg.conf.

This might also help the pixel errors in the lower right corner that occur on some machines. It disables 2D acceleration almost completly and let the CPU do all the rendering. Hopefully the driver will provide better XRender acceleration soon.

3D

If you plan to run Wine, you may need to tell fglrx to not corrupt the fs register. To do this, add the line: 

Option "UseFastTLS" "2"

to the "Device" section in /etc/X11/xorg.conf. This supposedly causes about a 10% hit in opengl benchmark scores, but at least things don't crash. See also http://wiki.winehq.org/fglrx and http://www2.ati.com/drivers/firegl/readme0325.txt
