Hey everyone,

We have just ported our project to 4.18.3 and noticed a huge slowdown for materials using a basic parallax mapping shader.

To give you an idea:

In 4.17.2, it was giving a 5% perf hit compared to “no parallax” shader
In 4.18.3, it skyrocketed to more than 40% performance hit.

Nothing was changed, exactly the same level, same assets etc… And the material looks visually similar, so I really don’t know where can come from.

Did any of you experienced the same thing?

Here is a screenshot of the material, so you can see how it looks like:

I did not notice any difference between 4.15 and 4.19
Something must have changed about your settings.(Deph pre-pass ? )

On a side note, max steps multiplier should be lerped between 1 and 1.2 not 0 and 1.2
