Skip rendering loop when there's no view changes

I built the viewer and tried to use it to load output of original 3DGS and got this error message:

This error is located in the LoadPlyHeader. The original 3DGS generated the ply file. Does incompatibility cause it?

Could you try supplying the full path to the .ply file? Reading the dataset folder is planned but not supported yet.

Thanks. It workes now. However, I noticed that the % gpu is always 95+ though I didn't change view angle. This behavior makes my mac heat up quickly. Do you have plan to optimize it?

Will get to this eventually - should be an easy fix. Feel free to submit a PR in the meantime.
