The switch has two effects:

1. It prevents you from loading any game saved with a larger vehicle 
array (in other words, the 'morevehicles' switch must be set the same or 
higher as it was when the game was saved -- otherwise you get a "Game 
load failed" message; normally you would probably get a warning).  This 
is the primary source of memory savings, since normally TTDPatch 
reserves memory for the largest array possible (more than 4 MB).

2. The cache for the ordinary TTD sprites is set to 800 KB instead of 
the usual 4 MB.  This may mean more frequent disk accesses, which in 
turn *may* affect the performance -- but frankly, I doubt you'll notice 
it much, unless you have a really slow hard disk.

Note, however, that new graphics are loaded separately, and add to the 
memory usage anyway (but on the positive side, they don't require disk 
access during the game).  Thus, you may get out of memory again if you 
add many new graphics sets to newgrf.cfg.

BTW, I've checked the latest sources; the behaviour of the switch hasn't 
changed since 2.0.
