it should be slow or not? :-)

Post by NDD »

I have just finished a browser by OGRE.
The programme runs correctly,but its frame rate seems too low...

I have put about 10 objects in the scene
when I just can see one or two objects,the
frame rate is good

But when it comes a perspective panorama.the frame rate is terrible...

The meshes and textures in the scene totally take 200MB ram.

Is it because too many details?

my test machine is a P4 3.0 1GB ram and nvidia Geforce 5200 with
64 mb ram.

Generally speaking,What magnitude of models is suitable to
rendering in OGRE and what is not suitable?

Thanks a lot:-)

I think that's the problem. When the scene/textures take up more RAM than is on the graphics card, it's necessary to swap the media from system RAM all the time, which will hit performance badly. You have to target the detail level to the system you'll be using--or target the system to the detail level you want. :)
