[krita] [Bug 409052] High GPU Usage
https://bugs.kde.org/show_bug.cgi?id=409052 --- Comment #19 from Boudewijn Rempt --- Git commit 1b1936b97e01c2b12eb844c9a07c5941031bf082 by Boudewijn Rempt. Committed on 08/07/2019 at 14:59. Pushed by rempt into branch 'krita/4.2'. Add NSSupportsAutomaticGraphicsSwitching to the Info.plist https://developer.apple.com/library/archive/qa/qa1734/_index.html suggests that this will make it possible for Krita to use the integrated Intel GPU instead of the discrete AMD GPU. AMD drivers on macOS are the pits, using Intel should be preferred for Krita M +2-0krita/Info.plist.template https://invent.kde.org/kde/krita/commit/1b1936b97e01c2b12eb844c9a07c5941031bf082 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=409052 --- Comment #9 from zoltron --- if you send Krita running on Integrated Intel GPU, I can test it. If you are considering an AMD hotfix, I believe it will not work because this is Apple GPU driver problem. maybe it helps; https://developer.apple.com/library/archive/qa/qa1734/_index.html https://apple.stackexchange.com/questions/217928/how-does-os-x-decide-when-to-switch-graphics-processors I've come across a Krita version that works with Intel before.

Of course we're not going to spend time and/or money on porting Krita to Metal. It's a proprietary API available only on a minority platform. I also don't intend to spend Krita money on getting a mac with an AMD GPU: Apple just doesn't sell any hardware worth the asking price at the moment. MoltenVK would only work if we'd port Krita's opengl to Vulkan, which is also not planned. If Angle would get support for Metal, then that would be an option. -- You are receiving this mail because: You are watching all bug changes.

Qt 5.12.3, krita master. It seems there could be something wrong going on with OpenGL and thATI card, but i can't personally take care of this since I have no hardware to reproduce the issue. Moving towards MoltenVK is something Im studying atm, but without solid knowledge on the subject I doubt I will come up with something soon. as for taking it seriouly, i am, but I had to ask first, im sorry I didn't catch the video sooner, the attachments are not very prominent design wise in bugzilla. Video can get us up to a centain point, however I see you are running krita from compiled sources… Let me ask the other devs, maybe we can come up with a patch for you to compile krita with that could give us some insight on what is going on and perhaps come up with a solution. I'm confirming this and assinging myself to keep track of this bug -- You are receiving this mail because: You are watching all bug changes.

Didn't you watch? almost everything that uses GPU the following uses a 100 percent GPU ( AMD radeon Pro 455.) -animation play -panning, zooming -every slider in GUI -drawing with brush -- You are receiving this mail because: You are watching all bug changes.

OpenGL is dead for macos and macbooks Apple are stopped OpenGL support since 4.1 version, you can use Metal API and MoltenVk or drop MacOS support. -- You are receiving this mail because: You are watching all bug changes.
