Performance issue regarding UI with Widget Blueprint.

Development Programming & Scripting UI

Hi,

We have a performance issue with UI for our RTS project.
The frame rate is outrageously low when UI is display.
The UI looks like the one of starcraft 2.

We make our UI with Widget Blueprint. We have some non “power of two” textures in PNG format with transparancy.

Any clue on how to solve this issue?

Thanks!

Hello GaryFunKing,

I have a few questions that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. What version of the engine are you using?
  2. Are you using binary or building from source?
  3. Is it possible that some of your widgets are doubling up(not being removed from screen and so stacking up when called)?
  4. Can you reproduce this in a clean project?
  5. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  6. Could you provide screen shots of any blueprints that may be involved?
  7. Could you provide screen shots of your UI or a more detailed description of them?

Hi Rudy,

Thanks for your response but we found the solution.

The performance issue was caused by a missing font in our project. So for each TextBlock there is a drop of 10 fps.

Thanks you again for your help.
