This is absolutely the last posts on this topic that I\'m going to do, this topic is getting really boring.

I wasn\'t arguing about these points in the previous post. I was talking about accuracy and the physics engine mostly.
I think you?re confusing a real physics, the stuff that really does require a 64-bit processor, with game physics. Everything I ever read about game physics tells me it isn?t even a cheap knock off, it?s an illusion.
Planeshift uses 4 byte (32 bit) floating point numbers and will NEVER use more than 4 GB of RAM on one machine, I assure you. :-)
I\'ll take your word for it. But my motto, never say never.
So why would vengeance say this?
The holy Bible takes up 7MB of RAM, Encyclopaedia Britannica took up 170MB of RAM when it was first converted to a CD, and you?re really thinking the development team has gotta come up with 4GB of anything. Can you imagine downloading 4GB of data even over a cable modem? Beyond that you\'re talking multiple DVD\'s.
And that is just to fill up the RAM on your computer.
Let me break it down for you, let?s say you have an almighty 4GHz processor. Let?s say you have a screaming fast 500MHz speed to your RAM. This would mean to look at every piece of RAM would take at least one seconds. Notice you go by RAM access speed not processor speed, sucks don?t it. That?s one second ,dead minimum, jest to get through the RAM, no game is executed. Yet another reason why your video card has a screaming fast DSP( Data Signal Processor) in it and a lot of RAM.
Seriously, I wonder how we came to adopt 32 bit in the first place if all the people kept on claiming how it was unnecessary and 8 bit or 16 bit was the way to go. Am I the only one who embraces progess ? I mean, sooner or later you\'re going to hit certain limits with existing technology. And Planeshift is advertised as a project that will never be complete - but always revised and improved. That make any sense?
The 32-bit processor was greatly anticipated. Nobody was arguing 16 bit was fast enough at the time... Well there were a few people there always is. When the 32-bit processor came out it proved to be a major milestone in processor technology. The same is not true for the 64-bit processor. That?s why these days there is a major discussion on changing the entire architecture of a computer.
64bit != speed necessarily. (C or VB notation what ever)
The only 4GB barrier in a 32-bit processor is in the x86 line. Once again legacy issues dictate that not 32-bit processors. If you?re building a chip from scratch you can do anything you like. You can have separate RAM for instruction sets and data. That will speed things up substantially faster than going from a 32-bit to a 64-bit. A 32-bit microprocessor can have 64-bit data lines. Or two banks of RAM and run them both separately.
You folks listen to Xandria. He is right.
There you go enough said.
