[Solved] Is there any way to specify how particles are processed? (i.e., via GPU or CPU)

Unity Engine

tl;dr could anyone tell me if it’s possible to set a sprite as a “GPU sprite” in Unity? (So it’s processed solely by the GPU.)

I’m developing on the hololens, and I have experience with UE4. In UE4, sprites are processed (their transforms and velocity and such) on the CPU by default. However, you can specify the type of particle as a gpu sprite, and doing that allows you to display “a lot more”.

I read the documentation on particles in Unity and couldn’t find any mention of how sprites are processed (no mention of gpu sprites whatsoever; at least in the 5/6 pages worth of Particles section).

I’d assume it’s on the CPU by default, too, but I can’t find any info to support that.

Could anyone give me information, or refer me to an article, about how particles are processed in Unity?

I found there are some addons that allow one to make gpu sprites, but I’m not willing to pay for that. After all, I’m just testing stuff.

Thanks in advance for any help!

As far as I know if you want to do something on the GPU like that you have to do it yourself or use an asset that does it. I do this with a particle system I wrote running on a compute shader. It’s not trivial.

Thanks a lot for taking the time to tell me this. It’s extremely appreciated. I’ll consider this question as resolved, thanks to you!
