Yes it's true.

I tried rewriting my scenery cache, for trees and other landscape scenery, in DB Pro and it ran about 15 times slower. The cache loads about 1000 simple 3d objects (most with transparency) and re-uses them as you walk around the map. In DB1.13 it runs at about 30-40 fps. In DB Pro it runs at.. wait for it.. 3 fps!!!.. even when all those objects are set to be invisible.


Lee or Mike, please tell me that you are fixing the rendering pipeline in the next patch.

Can you send me an example please? If you could send the code and all of the media I can test it out with patch 4.

We are making changes to the rendering code and you'll get to see this in patch 4.

ya, I've noticed slowdowns as well. When using the Text command over 3D, I get a drop of approx 10 fps.
This process:
Set bitmap to 1
paste images (2 or 3)
get image
set bitmap to 0
paste image

gets me around 12 fps.

It was around 20 in DBC...

"The cache loads about 1000 simple 3d objects"

well there's your problem.

if you didn't know already the pipeline in DBP is much faster with fewer objects but it much slower with many (in your case, 1000) objects. which is why mike wants you to send him your code, as the new pipeline is in P4

i'm looking at yooooou!

Yes the pipline is slower however that will be corrected when the new DBO format gets going as all 3d objects will be treated as the same type just with different properties applied

Yeah, Get image will be slower, in fact, some paste image calls will be slower too, well, slower than DB1.13 anyway. Remember, there is no 2D in DX8.1, so everything involving grabbing images etc will be a bit slow cos it has to be done a bit less gracefully.

BUT!!!

That's why we have memblocks and rendering to images . Has anyone tried texturing a cube with a camera view yet?, I'm guessing it'll look pretty mad.
