In the spirit of lively interest in the subject at hand (trueSpace) I would
like to pass on a couple of things I learned recently.
1. Watch the scale if your scenes or expect weird troubles. I made a
helicopter type vehicle and then created a scene around it with room enough
to fly around in. The grid looked like a postage stamp. At this scale, I was
doing a simple render with an anim painted on a rectangle and the animated
tecture seemed to change scale during the animation except when navigating
to an effected frame and rendering manually, everything was normal. After
scaling down the scene and normalizing the loacation, everything renders
normally. Go figure.
2. I just puchased an upgraded MB and CPU with fast RAM. Then I ran Sisoft
Sandra analysis and it pointed out that:
Tip T2546 - Large memory modules (512 or greater) should be ECC/Parity.
Since the probability that a bit will be corrupt is the same or increases
with module density, the bigger the module, the bigger the overall
probability that you will get one or more corrupted bits. While these
modules add an extra delay on partial writes (e.g. less than data width) as
parity for the whole line must be re-calculated, the stability will be worth
it.
Fix: If you plan on adding more memory, consider replacing the modules with
ECC/Parity modules. Do note that running plain and ECC/Parity modules will
turn off ECC/Parity for the whole memory array.
Tip T2545 - Large memory modules (256MB or greater) should be
Registered/Buffered, especially if more than 2 are installed on the same
channel. This improves signal quality by reducing the load on the chipset
channel. While these modules add an extra clock delay due to the on-board
buffers (thus CL2 effectively becomes CL3), the stability will be worth it.
Server chipsets with many memory slots generally require Registered memory.
Fix: If you plan on adding more memory, consider replacing the modules with
Registered/Buffered modules. Do note that you cannot mix Unbuffered and
Registered/Buffered modules on the same channel, but you may be able to if
the chipset has multiple memory channels.

Warning W2518 - Mainboard temperature is too high (i.e. over 50�C). This
should appear only if the mainboard has a temperature-monitoring sensor
installed.
Fix: Power down the system immediately. Open the case and check that all the
fans are working and check whether components are unusually hot inside. Make
sure the components have good all-round ventilation. Use more fans if
required.

So maybe trueSpace (rendering as we speak, has a tough row to hoe.
