Open the scene,let flip update,mark playone on timeline
Activate opencl,activate performance,play it

I take the Total statistics value

Now Houdini in CPU-OpenCl,what driver use?i cant make use of the AMD´s OpenCl driver.Houdini just use the Intel one.

Thanks!

Hi,yes another of those threads

Im new in Houdini,atracted by Flip solver,wonder if im doing things wrong

I feel Houdini slower than Naiad,not to mention its consume far more memory.

Even the display of particles its slower in Houdini.

I know Houdini its a big 3d app and Naiad its focused on just one thing.

But again seeing examples from the mighty Igor i see he keep using naiad and just translate the sim to Houdini for shading etc.

Wonder if you guys have the same experience or if im just doing things wrong,i even switch the particles from spheres to points,thats speed up things,but not to the level of Naiad.
