This is actually a somewhat infamous issue and it's much older than that. The
usual workaround involves either setting LARGE_ADDRESS_AWARE flag on the
executable (which tells Wine to apply a different memory allocation limit) or
patching Wine to the same effect. Proton even has a convenient
PROTON_FORCE_LARGE_ADDRESS_AWARE environment variable for that matter. 

In my experience this workaround results in lower virtual memory allocation by
roughly 700 Mb - 1 Gb. It's not clear to me how it does that, it's really not
supposed to.

Is there a noticeable difference in virtual memory allocation?
