What about this small change?
while (1)
{
lvl_sky.v -= 0.002 * time_step;
lvl_sky.u += 0.002 * time_step;
wait(-0.1);
}
I tried that as well. Sky is slower, although still fast for what I need and beside that, there is this stuttering effect as well.
Sky is moving smoothly only if I put wait(1). More than one frame or if I use seconds instead, stuttering effect appears.
