GPU Acceleration Issue

[Ralence]

When I set a brush to use GPU acceleration (or whatever the little gpu option under bristle amount is), the hardness setting seems to not work properly and the brush's edge becomes rigid. This occurs for every brush I bothered to test (most default brushes). anyone else having this problem? orz
On the left is without GPU acceleration enabled and on the right is with GPU acceleration enabled.
I use NVIDIA GeForce GTX 960 and windows 64 if that helps.

Not sure about this color scheme, but it seems you've enabled the aliasing (pixel art) button on the tool options panel. If it's not a reason, try to reinstall graphics card drivers with clean settings.

Similar to the phenomenon I saw.
But this may be a problem in my environment.
I attached the image as it might be useful for something.

Don't forget that Bristle brush works in a different way with GPU

The image looks as if you turned on the bristle, but only the gpu mode have changed.

In my PC environment, PaintstormStudio does not work when using selection with "gpu for bristle brush". So I gave up turning on the GPU with a bristle brush.
However, it may be turned on for the reproduction test.
It seems strange that the rendering result changes when the GPU is turned on or off.

Hard to describe why it happening, but it's correct (not a bug). The default mode for bristle brushes is "GPU OFF" But GPU ON can be useful for big brushes 200px+ on powerful graphics cards.
