I've had a support ticket open with Capture One since December 2021, which I submitted when I was running version 15.0.0. This is still true with 15.2.0.
Capture One 22 has a significant loss of performance on my machine when compared with version 21. I've tried everything that support has had me try, including deleting ImageCore versions and re-creating the kernels on startup, disabling/enabling OpenCL rendering (which doesn't seem to have stopped Capture One from using my GPU, as far as I can tell - GPU usage kicks up when I start fiddling with sliders or curves even with those values disabled in settings), ensuring that my graphics drivers are updated for my GTX 3080, sent in my RAW files and a session folder for analysis (no results), setting the image preview size to the maximum setting, and uninstalling/reinstalling the program.
If I pull a tool off of the docked toolbar on the side of my screen, leave the floating tool over my image and attempt to make adjustments while holding the Alt key (this is important, I want to have slow adjustments for precision and be able to temporarily reset changes to see the differences) Capture One slows to a crawl. This happens with curves, either adjusting curves or temporarily resetting them to see changes - C1 slows to a crawl. If I pull the color wheel tool off and temporarily reset the wheels to see the changes, C1 slows to a crawl and actually seems to permanently reset my color balance unless I release both the mouse button AND the Alt key.
Does anyone else see this kind of performance degradation on Windows with the same version, or did you lose performance between v21 and v22 like I did?
I am frustrated at the lack of adequate support from C1, and I'm not sure what else to do. I want to keep using this software, but the performance problems are unfortunate.
