Interpolation (car pos/rot) #184

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
At every fps (low or high) it is seeable that cam/car pos and rot aren't 
smooth. Game kind of feels like it had lower fps than gpu does. Enabling Vsync 
helps, but not much.
This needs investigation.
But I think it's the problem with that 160 Hz simulation frequency and 82 Hz 
game update. Also multi threading can have influence.

Check in game.cfg:
[ sim ]
bullet_freq = 160.000000
bullet_iter = 24
dynamics_iter = 30
game_freq = 82.000000
multi_thr = 1
thread_sleep = 5

We probably should use last 2 pos/rot states from sim and 
interpolate/extrapolate (for actual time at which rendering happens) to get not 
the last sim result but the result for given time. Probably extrapolated since 
rendering will happen after simulation result.

Closing, not time to test it, ancient issue.
