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).
