OS: Mac os 10.15.2

Blender 2.81a

RPR 2.2.1, just Metal 2

RX 5700 XT

See file attachment.

1. While working with simple particles (hair emitter without child simple/interpolation) the render so slooooooow that I  render something for Hollywood but not, it just simple scene!

2. When I check "child interpolation" in the children setting and set smth more than 150 for render amount my system freeze! And than restarted after ~5-9 min !!!

BTW, the same behaviour with RPR in Cinema 4D. See this post: https://community.amd.com/thread/246809 

What's the hell is that? Buffer overflow? Dead card? Dead drivers? Dead mac os? Dead AMD? This RPR absolutely not for work.

Hi! try to reproduce your issue, please try to render with the latest RPR version from the official page, because your scene works with Radeon Pro 560 GPU. Thank you

[irz]

I use the most latest version of RPR.

I can render this scene in Windows 10 but not in the mac os 10.15.2 with 5700 XT. You render correct in terms of colours, objects & particles.

As I can understand from your screenshot you are working under Linux with 560, but it's not the same as mac os + rdna gpu.

sorry, but that's a screenshot from MacPro with Radeon Pro 560 GPU

Rendered on

Mac Pro, 3.5 GHz 8-Core Intel Xeon W, 32GB RAM, Radeon Pro Vega II 32 GB w- Denoising turned on.

Vega II...

It's seems smth wrong with RDNA drivers under Mac OS 10.15.2

Apple or AMD should investigate this.

Here is render from Windows 10 (adrenalin 20.1.1, RPR 2.2.1, Blender 2.81a, 5700 XT):

In all for GPU particles render:

1. MacPro + 560 (denoise OFF?) , Time: 11:41.05

2. MacPro + Vega II 32Gb (denoise ON), Time: 06:34.69

3. Windows 10 + 5700 XT (denoise ON): Time 01:21.98

4. MacOs 10.15.2 + 5700 XT: Time: no. Hardware freeze.

And again... what the hell is that???

RPR (or may be apple driver) couldn't work with sync of multiply objects? Smth. wrong with driver/RPR architecture?

AMD, please, investigate this.

Thank you for all the detailed information. All new information will be provided to the team
