So, going over the install specs, and touching on SimonJM's question/issue, and from what I know regarding x86 software :

Why are the suggested RAM specs 8G (min.) and 16 - 32G ('good' mid-range) when x86 programs can only utilize up to 4G (if LAA) max?

The CPU simulation runs via cores, and I am guessing the GPU does the same (Cuda cores?). So isn't the base RAM only for springs storage along with object files in memory?

Is VWD somehow utilizing RAM beyond the x86 4G cap?
