> there's still an oddity left: for my Mass Effect binary, even upon setting the LAA bit, WINE still reserves 2G of VSS

I did a testcase: a 32-bit app that allocates 2.1G of memory, and ran it
without and with LAA bit set. It works in the latter case (memory gets
allocated from that reserved pool), so apparently having the reservation of VSS
does not make LAA-set apps to run out of memory.

So, with all that said, setting an LAA bit on a game executable may help. To
check whether it is set use `objdump -p app.exe | grep "large address aware"`,
there should be an output.
