Why does this happen?

[Arata]

Dan, why is that when I go into settings, and put the particle multiplier all the way up, the program then runs slow?
Are you planning to fix that?

[Arata]

I'm talking about universe sandbox.

Arata, when you increase the number of particles the computer has to calculate where all the particles have to go, so it will always be slower with more particles. It cannot be fixed.

try upgrading your computer that will help when more particles are on screen maybe a better graphics card that can process more particles and a better processor to help with the math for the physics part

or if any 1 knows if the ageia physics cards make any dif with US??

I don't think the video card has any problems with displaying sprite based objects.
It's probably rather a problem of the mainboard which has to calculate all the positions and velocities of the particles. Anyways, I think there are already quite a lot of cheap multicores out.

Unfortunately Universe Sandbox doesn't run any faster with an ageia physics card.

True.

Although Universe Sandbox only supports a single core at the moment. As soon as .NET 4 comes out I'll be releasing a new version that should run at least 40% faster on dual core systems.

Bottom line: A faster computer is more important than a faster video card with Universe Sandbox.

And Arata: Don't forget that you can edit your previous posts instead of adding a new one.

thx for the info dan can i ask if in the .net 4 version will it also support quad core as well or will it only use 2 of the 4??

[Dan Dixon]

will it also support quad core as well or will it only use 2 of the 4??

When the multi-core upgrade is released it will support as many processors as you have available: 4, 8, even 16.

So yes, it will support quad cores.

nice 

[monmarfori]

They only support cores of 2,4,6,8 and more. like i will buy Core 2 duo.
