Function of Option: Video Memory Usage

[gallomimia]

I have been curious as to what this particular option does. I did change it from low to All, but also at the same time as updating to 0.13.0 and turning on sprite compression.

It appears to me to decide how "nice" Factorio plays with other users of the video memory. By changing it to all, I have noticed very little if any slowdowns, and a drastic reduction in load time (From 3 minutes to 15 seconds)

This is on a system with only 256MB vram. It was nearly unplayable before, and now runs quite nicely, even under spec.

8gb ram (with 256mb robbed for vram)

If your computer can handle it the "all" option is the best as it puts all the sprites into VRAM so it doesn't need to swap them in and out as it uses them.

This is a very vital information not to be found elsewhere!
And not only hat particularly option but all of them should be described in simple wordings - some options are not so easy to understand as well.
Should be mandatory included in the users guide as well as your website 'getting started'!
I was long searching for that answer given.

Well. How interesting. Because my computer probably can't handle it, and yet it's much faster to use "ALL"

That is very strange. Could you post your log?
