long time ago, i have make some test... was able to have around 25000 LRM frigates in a gravity wheel... game have crash when i have try to make them jump all together to a other planet... surely a overload of particule effect for the shader...
Two quad core Xeon
16 gb quad serial channel interlease raid mounted ( yes, i can mount my memory in raid mode )... DDR2 1333 with ECC and 8 bits correction ( fully buffered )... max transfer speed is 30 gb/s ...
Nvidia 8800 Ultra 768 mb
and since Sins was advertised as Multicore in germany, after some months I finally went to return it to the store for complete refund.
If the guy from the store have refund you, he was stupid... sins use the second core for speed up the load of the game...
For the rest, main limitation is the windows OS and your material... sins can use more that one core and more that 2gb is the software layer below sins ( os, bios ) allow it... there is huge difference between a desktop, a workstation or a server... same the best desktop remain a low end computer !!!
For people with win 32 bits Os and who think that 4gb is the limit of a 32 bits OS, take a look at http://www.geoffchappell.com/viewer.htm?doc=notes/windows/license/memory.htm ... for info, the old Windows 2000 Datacenter support 32 gb ram ( it was before the time of XP )... for Linux user, from the kernel 2.3.23 the max limit is 64 gb ram on a 32 bits system...
For use muticore and multiprocessor, it is more complex and expensive... a other software, a layer beween the bios and the OS is needed...
Point is that your material and your OS limit what you can make... there is no technical reason to these limit, only license limit... from the pentium pro, computer was 36 bits ( max 64 gb ram )... and the actual processor are in fact 48 bits ( 52 bit physical but only 48 bits address range )...
If there is something that you need to return to the store, it is not sins but your windows OS... microsoft is selling you a limited version of their server edition and make you believe that the desktop OS limit are due to hardware when in fact desktop OS have the same code that server one, only some portion of the code is inactivated for license reason...
The only reason to move to the 64 bits material/OS is only money... money that you spend on these new computer and OS...
Ironclad have wrote a wonderfull piece of code with sins... limit are mainly due to OS... and 64 bit OS will not resolve a lot of think... Windows 7 home basic ( the more used version ) have a limit of 8 gb !!!! The expensive windows Ultimate have a limit of 192 gb... if a sins 2 go out, using 64 bits, it will be made for the more used versions of windows... with a limit of 8 gb only !!!
If something need to be fixed, it is not the Stardock/Ironclad programming skill but all the citizen Joe who buy low end product, install a limited version of a OS and believe the lies from these hardware/software big corporation...
