So! I've been searching for a render farm software that is easy to use, free, and gives me full control over what the software is doing. I've tried solutions like Sheep-It, but that eats up your internet connection because it takes your computing power to render who knows what. So this software which I recently stumbled upon seems to be a solution to my issue, but I need to know what outlandish things that are most likely a waste of time it can and can't do. So here are my questions:

Can it render up to 8K? (7860x4320)

Is there an OS limitation?(Windows 10, Mac OS High Sierra)

does it support old devices?(Geforce GT 620, Intel Pentium D)

Do I have to have a fast network switch?(I have 1000Mbp/s, so not actually an issue)

Is there a certain amount of resources you need to allocate?(I have only 1GB of RAM in one of the systems)

Is there a limit or minimum amount of systems you need to connect?(besides the first 2)

Do you need to allocate any amount of storage?

And, is it actually easy to use?(Haven't heard from support yet)
