I'm using a Nvidia GeForce 720 display adapter that supports OpenCl but I can't get Painter 2020 to use it. It appears the accelerator application recognizes it. How do I get painter to use it?
Some recommend starting program with Shift key held down and then choosing from the Splash screen Performance. Some have had to repeat process to get it to read hardware properly.
Thanks, I did try the multiple restarts and it still isn't using OpenCL. I think Painter read the hardware since it says OpenCL 1.2 - Yes but the next line still reads -- not in use.
I upgraded the nvidia driver to the newest - 1 version. The latest driver kept crashing my system so I went with the next most recent one. The new driver didn't fix my problem.
I have the same problem with my Radeon Fury X.
The Painter Brush Accelerator test compares the performance of your GPU to your CPU and determines what are the optimal settings for your system.
The most important thing when running this test is to ensure you do not have extra documents or applications open, as they can affect the test results. (so if you did have extra docs and apps running, consider closing those and re-running again)
After the test is run, the optimal settings are chosen: In some cases, the GPU is very strong and will create a noticeable improvement in brush performance--the cylinder will turn green. In other cases, your CPU may be very strong...so strong in fact, that it is the better device to use for all painting activities. In these scenarios you will see a greyed out cylinder because the GPU will not be used.
I suspect in your case, you CPU is stronger than your video card for brushing duties.
On my personal Painter systems:
System A: Has a GeForce 1050ti with a 2nd Gen Intel i5 processor. Cylinder is green, GPU is used.
System B: Has a Radeon R9M370x with a newer AVX2-compatible 2.5gz i7 processor. Cylinder is greyed out, GPU is not used.
For the record, both systems paint quite fast with Painter 2020, and paint faster than Painter 2019.
I hope this helps clarify...
