TRS2006 SP1 on Windows XP Pro x64 SP2

First, "a multithreaded software like trainz " is wrong, Trainz is NOT multi-threaded and will only use one CPU. You will find very few multi-threaded programs as they are abut ten times as hard to make.
 
If you look at the access patterns for a dual-core CPU, then one core is always in use a bit more than the other. However, this is due to trainz using one core and windows using the other.

Anyway, shouldn't the CPU driver spread the load evenly through each core?

As for what you are suggesting with regard to percentages, I cannot see a way of implementing it without rewriting the entire OS and any games that you want to use. But, using a 32-bit OS would solve your WOW64 problems.
 
I've had an idea. You could dual-boot the PC so that you have one copy of XP-64 bit and one copy of XP-32 bit. One for trainz and 32-bit apps, one for 64-bit apps.

If you do decide to do this, then look out for OEM software. This is the computer manufacturer's version and it is a LOT cheaper than retail boxed stuff.

Sorry if any of this is obvious.

HTH,
 
BUT . . . . .

Wouldn't the main reason to use XP 64bit is to get around the 3GB Ram access limitation in the XP-32bit ?

More RAM insures that full 2GB will be left for Trainz to use. Tranz can only "see" 2GB max of RAM.

Cheers everyone, After a SP1 install, should the version logo change from 2761 to 3, whatever?

During installation of my SP1 I ran into alot of patch warnings... i.e old file does not exsist......I just kept presing ok and it said update sucessfull! :D Trainz works great using one video card
 
william_leas, did you remember to re-install TRS2006 before installing SP1? SP1 must be installed on a fresh installation of TRS2006 that has not been run at all (not even as far as the Launcher).

If it has been run even once before installing SP1, you need to re-install Trainz then install SP1 without running Trainz at all.

The version should change to 3xxx (where xxx is a 3-digit number at or above 092)
