Power savings & hardware usage about imgui HOT 3 OPEN

There’s none yet but I would be surprised if dear imgui ever took 50% of CPU on a several-years old Intel card. Assuming the measurement are right, you may have a bug or bottleneck somewhere else and imho this is what you could investigate.

I never meant to blame imgui for the 50%, im using my experimental bind of SDL emscripten with browser canvas drawing. The 50% was the result of rendering with only CPU. With GPU acceleration the result is round about 2-5% CPU 10% GPU

I don’t think any recent intel card can’t render triangles with GPU acceleration so the question is the check what’s the rendering process used in that situation.
