It's a cost/benefit analysis and for 32-bit systems the benefits seem to be rather small, right?
Can we make the increase in resolution dependent on max CPU count or such and use cheaper divides on 32-bit in that case, while still keeping the code clean?
We'd expect only relatively large and new (and 64-bit) systems to run into resolution problems, right?
Thanks,
Ingo
