Hello everyone,
I’m experiencing significant performance issues on the Low end Mobiles (Redmi Note 7 pro) while using Unreal Engine 5.5. The GPU time is around 50ms, while the game and draw times are normal. Interestingly, the same project runs smoothly in somewhat newer mobiles (Narzo 70) with GPU time around 10-14ms.
Steps I’ve Tried So Far:
-
Testing Rendering APIs:
- Switched between Vulkan and OpenGL ES 3.1; neither significantly improved GPU time.
-
Dynamic Global Illumination: set to None
-
Virtual Shadow Maps:
- Disabled Virtual Shadow Maps
-
LOD and Mesh Optimization:
- Implemented Level of Detail (LOD) settings for static meshes.
-
Post-Processing is Completely Disabled
Observations :
- The Redmi Note 7 Pro (Adreno 612 GPU) struggles with GPU performance in UE 5.5
- Projects built in UE 5.2 or 5.3 run much smoother on same device
Questions:
- Are there specific settings or configurations in UE 5.5 that could explain this difference in GPU performance?
- Any suggestions for further troubleshooting or optimization?

Thank you in advance for your help!
