[prospect]Can vulkan be the basic resolution for Krita Gpu Compute future?

The problem is, as always, to get the pixel data to GPU memory and out of it. Or store all of it in GPU memory indefinitely, but then layer and image sizes will be limited. We’ve been discussing this well over fifteen years and have gone through a lot of experiments already. It’s not like we’re not aware of it… An additional problem is that various GPU’s and drivers actually produce slightly different results using the same shaders, and that’s of course a big problem. As for Daishishi’s remark…

PS: Speaking truly, I cannot imagine, what are the benefits for us to use Vulkan over Angle. Do you know any? Krita doesn’t really use any extreme features of GPU. Only basic textures uploading and rendering with simple pixel …
