I’m running the latest version of Darktable on Windows with an RTX 3080ti (OpenCL enabled) and every single slider change and subsequent edit takes at minimum 1-2 seconds to register/process.
The weird part is that my GPU/VRAM usage remains very low when using it but when I run darktable-cltest it detects my GPU and says OpenCL is available and enabled.
The full OpenCL test results are as follows:
Compile options:
Bit depth → 64 bit
Debug → DISABLED
SSE2 optimizations → ENABLED
OpenMP → ENABLED
OpenCL → ENABLED
Lua → ENABLED - API version 9.2.0
Colord → DISABLED
gPhoto2 → ENABLED
GMIC → ENABLED - Compressed LUTs are supported
GraphicsMagick → ENABLED
ImageMagick → DISABLED
libavif → ENABLED
libheif → ENABLED
libjxl → ENABLED
OpenJPEG → ENABLED
OpenEXR → ENABLED
WebP → ENABLED
