How fast is Realsoft3D on a dual Mac OS X G5 system, compared to Athlon or Pentium IV based processors?
You mean the ray tracing speed, right? It depends a bit on the scene in question. G5 seems to do better job with integers whereas Athlon is very strong with floating point computations. Back to top
Based on a few benchmark tests we have run, a dual processor G5 system is approximately as fast as a single processor 64 bit Athlon 3200+ system, with processors running with equal clock speeds.

I have a Windows XP system equipped with full 4G of memory. However, it seems Realsoft can only use 1.5 ..1.8 G and then I start getting "Not enough memory" errors. Is this a bug in Realsoft 3D?
The problem is in MS Windows, which allows applications to access only 2G of memory.Back to top
You can configure Windows XP to let apps to use 3G by adding /3G flag into your Boot.ini file. To do this open the Control panel, click on the System icon, on the Advanced options panel, press the Configuration button of the Start and recuperation section. In this window click on the Edit button inside the System start section and the Notepad will pop-up with the Boot.ini file opened. There should be a line like this:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
Add the /3G flag at the end, save the file and restart the system.
If you are running Realsoft 3D Service Pack 3, this is all you have to do. If not, then download also the editbin.exe utility from Microsoft and run it from the console window as follows:
editbin /LARGEADDRESSAWARE "C:\Program Files\Realsoft\Realsoft3D\Realsoft3D.exe"
for each application you want allow to take advantage of 3G memory.
