Thought id word this one differently. Why do loaded objects, that have not been displayed (SHOW OBJECT) drop the frame rate?

Also, once loaded and Hidden (HIDE OBJECT) if I face the cluster of objects the frame rate drops even more, even though they are not being displayed. Facing away from the hidden objects, the framerate goes back up to where it had dropped when the objects were loaded in.
I suspect that all Hide Object does is not draw the object to the screen,..but all other functions are hot and on the go.

The message below on framerates is a bit more detailed but the meat of the exercise is in this post.

Yes, Hide Objects, whilst not being displayed are still probably processed...

I would like to see a return of the DBC 'make object static' and 'make object dynamic'(?) commands.

Whilst BSP replaces their intended use, there was quite a lot of trickery that could be done with the commands.


God created the world in 7 days, but we're still waiting for the patch.

I think that you'll find that the portals that will a part of U6 will perform that job for you.

It is strange that hidden objects cause a hit though ... you aren't loading so many that they have to be paged into video memory are you?

What would be the max number of objects that can be loaded without paging video memory? Lets say a single mesh object texturemaped as a 3d sprite.

There's not really an answer to that, as it will differ for every card out there.

Agreed but there must be a rule of thumb,...
for instance,...Dark age of camelot supports about 400 on screen objects without lag,..most of these objects are grass and trees,..
,...then there is the overhead of ai, complex objects (npcs and buildings), a completel system of inventory, effects etc,...theya re doing that all with cards that range form 32 meg up,...ive playe d that game with a 32 meg and a 128 meg card,..and notice little difference in lag between the two. If the video memory is a limitation, then how do they get around it?

Perhaps their grass and trees are actually sprites instead of 3d objects?
