[SOLVED] Why do Quantum3D Mercury Bricks scale well?

[joshua123033]

In the description and even in the comments, it is said that this Quantum3D Mercury Brick scales well(

). But why?

Is it because they are just 3D accelerators or is it because they render odd and even scan lines? (https://www.pcworld.com/article/202...r-gaming-pc-with-multiple-graphics-cards.html)

Please don't go hard on me as I don't fully understand what 3D accelerators are and it would be helpful if someone explained it to me, thanks.

6 year old parts. SLI/Crossfire has mostly gone by the wayside.

So its just because it used to work well but now SLI/Crossfire doesn't work well? Not because of anything else?

Games need to be written to make use of that functionality. Most are not.
There is often a result of microstuttering, in the merger of two or more cards.
Many newer GPU's don't support it at all.
