GTK4 moved rendering to GPU and gave up on RGB subpixel rendering. I've heard, that this GPU-centric decision made it impractical to continue with RGB subpixel rendering. The article shows it is possible. So perhaps, the reason for GTK

And now, 4 years later, I still can choose only among micron and hynix for consumer DDR5 DIMM. No samsung or nanya which I could order right now. While micron (crucial) 64GB DDR5 (SO-)DIMMs are available since few months.

Even recent nVidia 5090 has 104.75 TFLOPS FP32. It's useful comparison in terms of achievable performance per transistor count.

Sure, not for BLAS Level 1 and 2 operations. But not even for Level 3?

Would be interesting to compare transistor count without L3 (and perhaps L2) cache. 16-core Zen 5 CPU achieves more than 2 TFLOPS FP64. So number crunching performance scaled very well. It is weird, that the best consumer GPU can 4 TFLOPS.

> length=629 If you work often enough with patches, you know it is not so rare you need to modify the patch itself resulting in different length. Please do not hard-code the length.

I've been thinking Blender uses OpenGL only for previews not for the actual rendering. Could not compute shaders be optionally enabled? The OpenGL 3.x hardware itself is capable of OpenCL 1.x including CL/GL interop.
