[Classic graphics] Optimising model performance

[biridius]

Hello everyone. I have an issue in my map where if certain models are displayed, the fps rate goes down.
Here's an example.
When Guardians are on screen, the fps goes down to 26 (top left corner). The issue becomes worse when there are more guardians and derived models on screen.

When I move the camera away so that they are not displayed, the fps rate goes back up to 46.

The model in question is attached. Is there a way to improve this situation?

You might want to plug it into here: Sanity Test
Maybe removing all those extraneous animations and fixing those bad issues might resolve it.

870 unused

Omg. Thanks! I assume I should remove the unnecessary key frames?

 

[General Frank]

Yeah. You can use this tool: MDLX Optimizer
Just plug it in an it will give you one out.
You seriously need to fix the geoset animation issues. Those are bad.

 

[biridius]

Thank you. Fixed the geoset animations. Still 26 fps though.

Unfortunately the optimiser doesn't seem to open for me. It's just a white screen. Tried on Edge and Firefox.

 

[General Frank]

Yeah, you need to drag and drop and mdx file onto the white screen and it will give you a file back.

 

[biridius]

Oh. That's very useful. It doesn't show any unused errors now.
Though the fps problem still persists.

Hmm, test it with other models, preferably normal wc3 ones.

Replaced storm guardians with footmen; normal guardians still use the previous model.
With footmen on screen the fps is closer to normal, so it must be the model.

Seems like your guardian model has 2306 triangles, while the human footman has only 372. So, each Guardian would have the render complexity of roughly ~6.2 footmen.

You showed us that with 8 Guardians you get 26 FPS, and with 8 Footmen you get 44 FPS.

But what about if you have 49 footmen on the screen? This would be roughly equivalent in terms of the number of triangles.

8 Guardians * 2306 triangles = 18,448 triangles
49 Footmen * 372 triangles = 18,228 triangles

If you put 49 footmen on the screen and that causes you to get 26 FPS also, then this is most likely a simple matter of the model complexity. To make a different model that you could swap in instead of the footmen and retain the same performance, you would need your new model to have the same complexity in the model (and not be more complex).
