Bug Performance in XR goes bad, why??

hi everyone,
i develop a project VR, but i have a trouble in the FPS.
when i run the project with out Oculus the FPS runs fine, when i connect the Oculus
the FPS downs to 10 FPS.
when i open the profiler apear the next probelm


i don't know read the profiler, but i guess the problem is a shader, but i dont know where to begin.
some one can help me please.
thanks to every one.

 

There is no quick fix here. Strip your project down to the bare bones, make sure you're using efficient shaders (mobile ones are often good), not drawing more than you need to, and especially not making too many draw calls (different materials). Quest is a mobile platform; don't expect it to perform like a desktop.

 

ok, i will try to verfy the textures and all graphic. but i use the Rift S no Quest. i think this is the worst problem.
