Performance regression in 4.7.0 preview

My problem is as follows:
In 4.6 I’m getting 40-60 fps on my map that has relatively large amount of foliage.
In 4.7 preview I’m getting less than 1 fps on the same map I. I migrated the map and its assets to a new project and migrated that to 4.7. GPU visualizer shows that most of the time is spent on rendering cascaded shadow maps, which takes 50 milliseconds per cascade.

TL;DR: I get a 98% drop in performance.

I attached my dxdiag file just in case.

I also sent the a test project to , I won’t be posting it here since the assets are part of a project that isn’t public.

Hey jonimake,

I am downloading the zip file your provided now. I will let you know when I have tested your issue you are reporting!

Thank you,

Just a heads up, something in the new 4.7.0 preview 5 seems to have fixed my performance problems.

I was actually going to ask because we fixed a game breaking issue with Foliage causing projects to break (mine included). With the fix came the new improvements upon foliage performance as well!

Glad to hear!

My framerate dropped from about 45 to 22 after migrating to 4.7 preview 5 from 4.6.1 (landscape + small amounts of foliage).

Just to let you know, the foliage instanced static mesh performance improvements have not been implemented within the newest preview build.

@Tkorkalainen have you attempted to rebuild your lighting?

Thanks for the information and help. I’m not using lightmaps (Force No Precomputed Lighting).
