upyr1 Posted September 8, 2008 Author Posted September 8, 2008 The 32bit application will still use maximum 2Gb Ram. No matter how much is installed. And no matter if OS is 32bit or 64bit. You have for Example 12Gb Ram. The application uses and need 2Gb Ram>you have 10Gb left for other application. edit: There is no "first 4gb of Ram". When you have 12Gb Ram, then you have 12Gb Ram. Windows x64 will not start an Windows 32bit Emulation and reserve's 4Gb Ram. It will start the 32bit Application in a kind of "compatibility" Mode. It sounds like there is an advantage- even though 32 bit aplications don't use more than 2 GB of RAM you can load more 32 bit aplications up at one time- so if your running 6 programs at once- they would in theroy could be given 2 GB a piece where the 32 bit they would be at best fighting over about 3 GB of RAM.

That and the ability of 64bit systems to handle a greater number and larger files faster than 32bit systems, even if the programs themselves run as 32bit applications. Besides that, more and more programs will get the option to identify larger amounts of RAM. As there is only a little optimization needed and just a line of code to use up all RAM, I guess many programs will follow examples from Maya and Co and will soon use this option to get the max out of modern high-end-64bit-PCs.

upyr1 Posted September 9, 2008 Author Posted September 9, 2008 Would it be possibly to see a 64 bit option in at least the A-10 addons?
-Skipper- Posted September 9, 2008 Posted September 9, 2008 As a first step it would be enough to insert the line of code to disable the 2 Gig of RAM barrier if the system has enough RAM installed. Anything beyond, maybe with the new code? [sIGPIC][/sIGPIC]
