ios - Xcode FPS Debug Gauge always show 0 FPS -
i have game in xcode 6.1.1 using opengl es 3.0, targeting ipad air. when capture opengl es frame, fps number , shader program time show 0.
i have enabled "gpu frame capture" option in project scheme. frame rendering called cadisplaylink
in non-main thread.
how can correct fps nubmer , program time?
i came across similar issue. if implement uiviewcontroller setting eaglcontext layer xcode not display measurements except memory , cpu performance,instead of should use glkviewcontroller implementation.
for example:
replace below line
@interface myrenderingview : uiviewcontroller <...>{...}
with
@interface myrenderingview : glkviewcontroller <...>{...}
this makes difference.
another way:
use "xcode->opendevelopertool->instruments->gpu driver" run app, tool displays fps , other gpu information needed.
