Tessellation on or off?

[{0}Salamander{0}]

As per the title.

Should we run with tessellation on or off and what are the benefits and drawbacks (if any?).

This guy explains what it is quite well. https://www.youtube.com/watch?v=p_VpAMaxwpY

If your pc has the power to run it or you don't mind having a little less fps, go ahead and put it on. Otherwise I'd recommend to turn it off.

To put it simply, Tessellation effects mesh detail (a model's polygon count). It can improve visuals at the expense of performance.
