Thanks for the report, dee. Does performance improve for you on this level when the Feraxes are off screen? If so, it's probably because they use a fairly complex particle system; trying lowering the 'Rendering Detail' setting in the 'Visual Options' menu to get the perf back.
Cheers,
Dave

Hi Dave, low details did not help, fps on my machine depends on game speed (slowing down helps) and number of objects on screen (zooming out makes it slower, eating objects makes it faster). Deadly ecosystem forever 101 starts at 3fps, 4-5 after decreasing game speed, but it's still playable and cool

Wow dee! You're at deadly ecosystems forever 101?? That's crazy!
So ummm... yeah, I'll think about it, but 101 Ferax brains simply take a lot of juice! I guess that's what we get for releasing infinite content!
Thanks for the feedback!

Hey dee -- if you're down for it, we'd *love* to see a youtube gameplay vid of you playing one of the crazier deadly ecosystems levels.....

While I've not quite reached the realms of three figure ferax banter, I'm not far off. See below youtube vid for a demonstration of how to eat 96 feraxen
http://www.youtube.com/watch?v=arfIB53BcdIMy system is a dual core Intel Core 2 E8400 (3GHz) with 2 gig of RAM and an ATI Radeon 5770 graphics card, which is not to be sneezed at, but it does struggle in the early stages of levels with such ludicrous numbers of feraxes ... the only solution is to eat them and reduce the brain count

hahaha -- Phil, you just made my day! And I thought we had made the end-game content hard enough.
Awesome video, thanks for posting!

I killed the ferax pretty easy by accelerating toward him from the start and chasing him around the board. guess I just spawned a lucky board...

Hi, I tested version 1.6. It starts at the same speed, 2fps with 159 feraxes. Directx mode starts at 1fps. I can't explain it without thinking that game issues several draw calls per sphere, something like
Code: Select all
for(each sphere)
{
bind texture1;
glBegin();
render one quad
glEnd();
bind texture2;
glBegin();
render one quad
glEnd();
}
If I'm right, you can make game massively faster by simply reordering several lines
Code: Select all
bind texture1;
glBegin();
for(each sphere)
render one quad
glEnd();
bind texture2;
glBegin();
for(each sphere)
render one quad
glEnd();

Hi dee,
Thanks for your comments. I can assure you -- the Osmos renderer is heavily optimised.
159 Feraxes is alot of Feraxes! At this point, I'd expect the AI computation to be the bottleneck rather than the rendering. If you lower the rendering detail via the 'Visual Options' menu, do you see a framerate increase? If the answer is 'no' or 'marginal', then AI is your bet

Ok, sorry for suspecting you, GL path looks very clean
Now only CPU with faster 1thread execution will help...hmm, I wonder whether your AI can be parallelized
Code: Select all
#pragma omp parallel for
for(each ferax) ai_move();
