I’ve spoken to Ben and to address your questions:
He mentions 2gb of memory. Is this system ram?
- 2gb is actually the addressable amount of memory in a 32-bit process. Parts of that may be mapped to the graphics card, parts of it can be swapped out to your page file, but yes - 2gb would be the absolute maximum amount of memory it would be possible to allocate.
Also, could we get some info on how to test to see if your game is within this 2gb memory limit?
- While it is generally faster due to reduced cache misses, I think all our games ship 64-bit versions only now. The sure-fire way to know that you fit in memory is to try it.
Have a great day
