3. If you have 16GB of RAM, your MAX RamDisk size will be 10GB, leaving 6GB (more than enough for most 64bit games (most are 32bit and can't directly address larger than 3.5GB due to addressing limits) and your OS (64bit Windows)) to operate in normally. If you have 32GB, this cap will be lifted to 26GB. The RamDisk estimated (these numbers are NOT final and may be adjusted as needed based on user performance reports) max disk sizes based on total RAM are as follows:
6GB (Minimum total RAM supported): 2GB RamDisk (4 Reserved)
8GB (Average 'gamer' total): 3GB RamDisk (5 Reserved)
10GB: 4GB RamDisk (Full 6 Reserved)
12GB: 6GB RamDisk
14GB: 8GB RamDisk
16GB: 10GB RamDisk
32GB: 26GB RamDisk
There's a method to the madness, a science to the math. ;-)
Are you planning on putting in a setting to override the defaults? I have 32GB of ram, but I would only want a 20GB RAM disk. Also, some games are huge and may use all of that, but some games are tiny and would be swimming in 4-8GB of RAM disk...
