POM material

I Hevedy,

Good question! We just actually started making a testmap to put into our QAgame project so we can get a better idea.

So far it has various levels of POM on terrain etc but the next step is to make the same comparison with tessellation, attempting to make a few versions that look visually comparable to see how they perform against eachother. With 4.8 coming out soon some things are a bit hectic around here so I am not exactly sure when we will have any findings to share.

That said, I would expect POM to perform very well against tessellation, especially on terrain where tessellation is very slow. A lot of it will depend on a per-asset basis such as the noise frequency of the heightmap etc. There could be cases where one or the other are preferable. Ie a very low resolution lumpy form may look ok with low tessellation levels whereas something super noisy may require more POM steps to look good.

At a certain point using real geometry also wins its mostly for cases where it would be prohibitively difficult to make all those meshes (ie, tiling castle textures everywhere).

Thanks you
And about the normal parallax or pom how much faster is that comparing with the tessellation or the POM with PDO ?
