Can someone please give me an indepth explanation as to why the CPU vs GPU sims look different?

I have noticed when making a fire sim, GPU gives a bit more streaky and jagged sim (better licks) than a CPU sim which tends to be a bit more billowy with more ‘shrooms’ or rounder shapes in general.

Sadly GPU crashes on any large scale sims yet I really like the look.

How can I get CPU sims to look as streaky and jagged as GPU?

Any tricks to stop a GPU sim from crashing?

Cheers!

The sim should be the same whether running OpenCL on the CPU or GPU. Toggling openCL is more likely to be the culprit.

Cheers, sorry I meant Open CL using the GPU vs simply not using Open CL.

I didnt know (Atom on odforce mentioned)you can change it to Open CL CPU in the .env file.

So thats great, do some R&D with OpenCL GPU, then final sims with CPU Open CL!
