How much memory can 32-bit applications in Wine use?

Post by Rabcor »

Lets say as an example I am runing a 64 bit Linux (like most sane people with modern hardware) with 32-bit (multilib; the standard version of) Wine on it.

Linux has Physical Address Extension(PAE) support for 32-bit applications for up to 64GB of RAM. Can Wine make use of this? or is it (like Windows) limited to 3.25/4GB of RAM?

If it doesn't support this out of the box, is there any way I can make it support it?

Rabcor you have asked a very horible question. Lot of windows 32 bit applications are not designed in ways to take advantage of the extra memory provided in PAE mode 32 bit or 64 bit Windows. Reality if application is designed in ways to use more than 4G can be used it will be with wine. Why is this the case items like mmap(memory maps) are passed down to Linux to manage.

Wine 32 bit is the same on a 64 bit system.
