OK, So I was thinking...

A good sim is a big sim.  A big sim is a sim with a lot of RAM. However, x86 CPUs only go up to 4 GB. Should we upgrade DB to 64bit, perhaps so we can use a bajillion bytes of ram? that way we can make a cool sim. so ya.

I was thinking that, since most computers already support x64, and since RAM gets cheaper every year, perhaps this might be important enough for us to do to DB2?

Numsgil:
Sims aren't pushing the 4 GB limit at present, so probably not necessary.  I think you'll blow your CPU budget long before you run out of RAM.

Logistically, Visual Basic 6 is not 64 bit-able.  .NET is, sort of, but there are some 32 bit assumptions that need to be made for XNA, etc. that mean that it's not strictly easy to go 64 bit.

In this case store more, calculate less. Collision detection, for instance can be speeded up by octree searches

happyhamsterchan:
Do we already do that nums?

Numsgil:
That's called a broadphase in physics, for the record.  Yes, I think Eric implemented a simple grid for a broadphase.
