BIG UPDATE:
Disabling vulkan fixes the issue in the mali device
and here is more details about the issue in profiling.
It seem the issue is related to vsync.
frame sync time is a lot in a frame and little in another frame making this spikes
now the question is: why the heck does it want to vsync to 30 fps??
Smooth frame rate is disable and fixed frame rate is disabled ( setting it on and 60fps is same thing no change )
smooth frame rate is disabled as well
any help to fix this?
