memory-limit

Just out of curiosity could a lite-c application use more than 2gb system memory resp. even 128gb on e.g. a win server 2008 system?

Why not, a program uses as much memory as you need for it, when you define more entities you will need more memory, with a million big entities you probably need more than 128 GB.

I think the maximum what you can use is 4 GB, becourse GS is a 32 Bit application and with a 32 Bit application is the maximum RAM what you can use 4 GB (mathematically). But in reallyty can you only use 3.5 GB (for example Win XP 32 Bit). So i think it is the same with 3DGS.

@White_Wolf: That limitation has to do with the processor, not with the application.

That's not true with 3DGS, at least not A6.

@Michael_Schwarz

No, that is not correct. The limitation are give by more thinks as only the processor:

1) prozessor (not the problem, then all processors since 5 year or so, are all 64 bit processors)
2) the the motherboard (motherboards for privat user can use since one year more the 4 GB RAM. At the moment maximum 16 GB)
3) The OS (operation System). If you use a 32 Bit OS on a 64 Bit processor, the processor only use the fist 32 bit of his 64 bit. So that you can only use 4 GB (but realy you can use only 3.5 GB for example by XP 32 Bit)
4) Aplication if you start a 32 bit application on a 64 Bit system thay can only us 4 GB per application (becurse it runs in a simulation of a 32 bit system (in a 32 bit Environment), and per application why every application get his own 32 bit Environment:

Ya I second white wolf. I took my micro processors finals recently, and got an A. If I remember correctly the processor is a major part of memory limits because of the address but. But the motherboard itself, the available slots and the address bus of the board also need to be considered.

Well i guess A7 compiles always win32 executes - that musn't use more than 4gb.
A simple 'there is the limit' or a lovely 'thats absolutely nonsense' from jcl would be nice.

btw many desktop mainboards only support a value between 32 and 64bit memory addresses - so one can sell more boards
