I don't understand how 32-bit OS's use RAM on a per process basis. I've read the max RAM my x86 processor running a 32-bit OS can use is 2^32 = 4GB; but that's just for one process, right?
3DS Max keeps crashing, but it typically can never use more than 2GB of RAM before it crashes, if I increase my RAM from 4-8GB, would that double how much RAM I can use for each individual process or actually cause no change in my performance?
Additionally, would increasing my VRAM and getting a better graphics card increase the extent to which individual programs can preform? Lastly, is there any way to upgrade a 86-bit processor to be able to run a 64-bit OS? I feel like it would be ridiculous to sell modern processors that are capped at 4GB of RAM.
