With its current architecture, QtQuick has input latency issues: The scene reacts to user input with a slight, but noticeable delay, which makes QtQuick apps feel clumsy and unpleasant to use.
I guess this is related to vsync handling, where input events don't immediately trigger a repaint while the render thread waits until the framebuffer is swapped. The only exception are Windows platforms with native OpenGL on ATI cards, where the framerate seems to be uncapped: The rendering is super responsive, almost like Qt Widgets. The drawback is that render thread animators are broken, as they aren't synced to 60 Hz. 1. Is there a way to hack Qt to get this Windows+OpenGL+ATI rendering behavior on all platforms? Maybe some tweaks in qsg*renderloop.cpp? 2. Are there plans to implement a rendering scheme that reduces input latency? Thanks Willem
