DOTS makes the game slower. Why?

Hello.

I'm just starting to work with DOTS. Without writing any code, I just wanted to convert the simple objects to DOTS to be able to see the performance benefits of it but the result I experienced is very surprising in a bad way.

I'm using Hybrid Renderer 0.4.2 and Entities 0.9.1.

To test this, I imported a 3rd party forest scene from asset store. It runs around 260 fps in Unity editor on my computer.
Then I added ConvertToEntity component to all simple objects in the scene such as trees, walls and barrels. Fps dropped to 188!

Hey! what's going on here?

 

Got the same effect recently,
the Hybrid Renderer v1 is very slow and that is what causing the fps drop.
the new version should be out in 2020 and it would fix that issue.

 

Which pipeline you using? For DOTS preferred SRP with Hybrid Renderer v2, v1 much slower than that.

 

Things to try -
Disable safety checks
Enable material instancing
Use static optimize
Profile in build

 

Is it currently possible to use HR v2, using only packages installed through the Package Manager?

it’s been a bit difficult to track down info on this.

 

Yes with 9.x of either srp(though there may be issues given what Ive read here and on discord).

 

Check you Leak Detection setting in Jobs tab.
