RealFlow Official Forum

I just got a Ryzen 1700 with Radeon pro Duo 32GB GPU 32GBRAM 2400MHz.
As youtuber, I have this card for a couple of weeks, its a Dual GPU packed in to one card 16GB each.

Is there a way to draw maximum performance from them? To make the most of them while Simulating and Rendering?

Thanks in Advance

Here is a Test hybrido I did.
Test the Hybirdo RBD scene file simulate for 31:09 minutes

No Open CL Ticked - 42 Frames - 100% CPU ussage

CPU Open CL - 123 Frames 20-25% over all CPU ussage (4 cores were touching 80-100% rest idle)

GPU Open CL 38 Frames 100% CPU ussage

CPU + GPU CL 121 frames Frames 20-25% over all CPU ussage (4 cores were touching 80-100% rest idle)

View port enabled.

My test conclude,
Open CL, lead to 3 times faster SIM
GPU making the Sim slower - need to investigate more.
Realflow does not take advantage if DUAL GPUs while rendering - need to investigate more

Would really love an answer to this, I think it will really help studios as well...
Thanks in Advance

Hi,

Unfortunately RealFlow doesn't support MultiGPU yet. You will need to choose the graphic card you want to use in the simulations options. Also, try to use it in command line to make a better velocity test. Also, try with Dyverso solver since is fully optimized to be used with OpenCL and GPU.

Here is a Single GPU test done using Dyverso.
