Testing MAXIMUM_FRAME_LATENCY=1

[Jim Liak]

Hi, I did a test, recording via my phone's slow motion recording ( @100fps).

I then counted the frames needed for the virtual hand, to move :

Results
MAXIMUM_FRAME_LATENCY=0 (38frames)
MAXIMUM_FRAME_LATENCY=1 ( 27 frames)
MAXIMUM_FRAME_LATENCY=2 ( 34 frames)
vync 0ff , fps uncapped (~103fps) : ( 21 frames)

So it seems that MAXIMUM_FRAME_LATENCY=1, it's not really bad since ~6frames are added over vsync on = 60msecs. It's not that bad.

Are you sure to have always this levels of input lag?
You should try also with a moving scenery that put more load to GPU.
In any case, I always go for minimum input lag, accepting some screen tearing, so I don't mind for vsync.

I don't know how you drive like this. 1/4 of a second is incredibly high lag.

Me neither...
