Today I started to play a little with foliage and dynamic lighting in UE4.16. And I noticed that my fps drastically fall down.
I remembered that it worked better when I previously tried to do something.
I’ve asked our Designer to create a quick comparison.
And guess what? There is a big difference in performance between those two versions 4.10 and 4.16.
In both cases, the scalability settings are the same. Only one directional lighting. Maps are the same. And you see the difference in fps. Missing 5ms, just by switching UE4 version.
I know that 4.10 was just after the big show about Open World, Kite Demo, Mountain Landscape - all aspects of the environment were great.
I’m sure that by developing an engine for over a year you made it even better in each aspect. And I assumed that rendering performance should be improved as well or at least don’t go down.
Can you say what changed? And more important how to get back missing 5ms?
I’m asking because I’ve started a new project in 4.16 and I’m not sure if I should continue it in this version if there is so big performance gap.
I’ve checked this and looks like it is not related to LOD. In both versions, LOD settings are the same to the level of billboards.
But I found info in this topic that UE4 is just ****ed up if it goes for foliage.
Yes, there are few trees in the scene. Look on the kite demo - you will see what it is a ‘lot’. About Kite Demo, in version 4.9 it worked for me on 35-40fps without a problem. Now it is almost not working - 5FPS is a joke.
