Hello everyone, I am developing a mobile game with UE4. But the FPS is very low (15 or 20), I tried the research I have done so far, but I could not solve the low FPS.

Here’s what I’ve tried:

- Mobile HDR disabled
- No Shadow
- Only 1 static lighting
- 512x512 texture sizes
- LOD

I also have music and a HUD in my game, could this be causing fps drops?

Also my game stats:

What mobile device are you using and what are its specs?

A frame time of 1.79 ms would give you about 559 FPS. The stats you have shown don’t align with your claim of bad performance. Were these stats taken on a PC or from the mobile device?

For reference, a frame time of 1.79 ms results in approximately 559 FPS (1.79/1000 = 0.00179 seconds per frame). In contrast, 16.666 ms per frame corresponds to 60 FPS (16.666/1000 = 0.016666 seconds per frame).
