K well, I have a bunch of objects in my game and its really startin to slow down. So i was wonderin, If I hid EVERYTHING that wasnt in my FOV, would it make my game run faster? And how would I do that. I searched the help thing for a while, but all I came up with was set FOV and that wasnt muh help. Thanks for the advice.

there's an object on screen check command, I don't know what it is off the top of my head but i'll check, and it tells you if an object is visible and not behind any other objects. You could use that and hide object to acomplish this task...

now that I think about it, I dont know if that would work, cuz I may have a group of trees together, and when I look at the trees, it slows down, and when I look away from them it speeds up. So would that really be the way to solve it?

Try this:
for n="first object" to "last object"
if object exists(n)
vis=object visible (n)
if vis = 0 then hide object n
else
show object n
endif
endif
next n

not sure it will make you gain many fps tho

check the number of polys on ur tree, maybe u need to reduce them anyways i don't think the fov stuff you where talking about would help much 'cus since the objects are not visible on screen (not rendered), they are kinda virtually hidden (i think). what u need to do is maybe have a circular perimeter around your main character and anything outside is hidden while everything inside is visible it's been done loadsa times just scan the forum

you can still speed up the fps rate by...

for a=1 to [# of objects]
If object exist(a)=1
If object in screen(a)=1 and object visible(a)=0 then show object a
If object in screen(a)=0 and object visible(a)=1 then hide object a
Endif
next a

this should speed up you fps rate by 2 to 5...also if you have fog then set the camera distance to 10 or so more than the fog distance...this will also speed up the fps rates...well...hope this helps...

there's a post somewhere, it'll be on either page 1 or 2, its quite new, where somebody else was trying different ways of speeding the game up. the topic is "two seperate slow down issues", you should look there, it was quite detailed and it worked.

incase you can't find it, i said in it (i think it worked) you just make sure that the fog is turned on, the Set Camera View only goes a couple of hundred behind the fog, then anything that is in the fog (that you wouldn't see anyway) you hide, until it nears the end of the fog and you show it again.
you just need to come up with a way of finding the distance objects are away from you.
you could also expand it so that if an object is between 100 and 260 degrees from you, you hide it, as it would be behind you so you can't see it anyway
