Can't use Minimal OpenCL Solve

[NYXD]

Hi! I'm actually trying to get trough the tutorial series of Houdini "Destruction FX", and I need to use the Minimal OpenCl Solve for a Pyro Sim. But as soon as I turn it on, my console pops up with tons of errors showing up! I couldn't find something talking abt it on the internet as it is a pretty new feature, so if anyone knows how I could solve that it would be perfect. Here is the massive error message:

wanna share your computer specs? could be drivers, hardware...

what precision are you using for your grids?

I'm working on a pretty old laptop with a geforce 720M, an Intel Core i3 3110M and 8 go of RAM. I checked my graphic driver with Nvidia Geforce experience and it seems like I've already the best one for my laptop...

And sorry but I don't know what u mean about my grids? Wich grids? (I'm a beginner) I drop u the .hipnc file below so you can check everything u want!

The errors indicate your card is missing an extension for double precision float types (64 bit float). But the 720m supports OpenCL 1.1, which should know this type. I guess updating drivers couldnt hurt, but dont expect too much.

I have a 780gtx in my rig and while eg. the minimal solver shelf tool explosion technically works, its hardly usable for anything than a really, really coarse preview (exceeding vram i guess). When it works its fast tho.

Since my gpu is from the same series I tested your scene and it works fine. Maybe its better to ask the sidefx forum, since thats a bit closer to the devs.
