Having worked on a graphical application in rust for a (albeit not a complex one) computers today are fast.. latencies top out at 3 ms with cpu based rendering in an application with just a few rendering optimizations.

The fact that you just draw on the screen instead of doing whatever html parsing / DOM/IR is probably doing it? And doing rendering on the gpu means extra delay in the processing moving from cpu to gpu and being a frame behind because of vsync.

Can you clarify this? Seems to me that no matter how you render your UI, it has to go to the GPU framebuffer at some point.

For any non-trivial case where I can enable GPU acceleration for an app, it's been anywhere from equivalent to much more responsive.

What apps have you experienced delays with by enabling GPU acceleration?

Where it really shows up is stuff like power usage and reliably hitting framerates even on slow machines with big hi-res monitors attached.
