Corel Painter 2020 application uses the GPU on a machine to enhance performance. The application has a Brush Accelerator assessor that determines which components (CPU, GPU, memory) meet the minimum requirements to support enhanced performance. My system exceeds the minimum requirements in 3 of 4 categories (CPU cores=6 vs 4 minimum, GPU supports OpenCL 2.0 vs OpenCL 1.2 minimum, memory=24GB vs 8 minimum). My CPU does not support AVX2, which is the 4th area. My GPU is the Radeon Pro WX7100 with BIOS Part Number 113-C9540101-105 (BIOS Version 015.050.000.001) running the 19.Q2.1 driver on Windows 10 x64 (1809) with 24 GB RAM and 1TB SSD system drive, yet the Brush Accelerator reports that it cannot use my GPU for acceleration. This is odd since the WX7100 exceeds the GPU requirement for OpenCL. Anyone have this experience? and a resolution? Trying to determine if this is a application issue or GPU issue or something else.
The 19.Q3 release of the Radeon Pro driver seems to have something in it that makes Painter 20/20 now at least recognize that the WX7100 is present and supports OpenCL 1.2. However, for some reason, it won't use it. Anyone have similar (or different) experience?
I have exactly the issue that dealio describes. The performance test on Painter 2020 shows the GPU supports OpenCL 1.2, but lists it as "not used." I'm going to put in a support ticket to Corel, and I will post the results here if any.
It will be interesting to see what Corel says. At the time of the post above, I checked the Corel forums and no one had mentioned an issue with Painter 20/20 and the Brush Accelerator (name of the Corel in-app tool that assesses performance potential of the computer). But since with the 19.Q2.1 driver the Accelerator didn't recognize the WX7100 and with the 19.Q3 driver it does recognize the GPU (even though the app won't use it), it may be driver-related.
Im having the same issue on my RX Vega 64. (19.8.2 drivers)
The software recognizes the card as AMD accelerated parallel processing gfx901 and wont use it to accelerate brushes.
I did a test on my old laptop which features a firepro M6100 and everything is working fine and the card is recognized properly.
I sent a mail to the corel support and they answered that the gpu is not in use because the cpu (ryzen 7 1700) is faster than the gpu at openCL workloads (which sounds weird).
One way that could be accurate is if the driver for the RX Vega is not efficient in its implementation of OpenCL. In that case, Corel's Accelerator might determine that the CPU is faster than the GPU, and then ignore the GPU.
Attached are screenshots. In my case, OpenCL 1.2 is used by the integrated Intel graphics, but not by the discrete AMD Radeon card. The integrated card is running Painter 2020 more than 5X faster than the “fast” card. I use a 4 year old Dell laptop, but it's pretty damn fast, even when rendering from SolidWorks. But painter refuses to use the fast graphics card? This doesn't seem right. I have submitted a ticket.

Just a note, I just submitted the ticket. I got busy and just haven't had the time, and Painter is actually working well using the Intel integrated graphics; I was just having problems with the AMD discrete graphics card.
I did a similar test with my older Dell precision which runs on a firepro M6100 (which I believe is based on a radeon 7870) and on my Wacom msp 16 (which has a quadro m1000m) and had similar results, whereas my vega card is not even properly recognized. Sent another ticket to Corel's support but they just dismissed it by stating again that the card isn't fast enough to cope with the cpu, which obviously is not true.
At this point I'm guessing they just forgot to add support to newer generations of AMD products.
