Vsync API

[ghost]

Will be support for vsync on/off api in the future?

I must ask do you mean like the ability to have the setting to say for example

 new Canvas(size_w,sizw_h,aa=false)

or like in line
being able to inline say

window.aa = false

[ghost]

I mean as glfwSwapInterval(mode) of GLFW where mode is 0 (Unlimited FPS) or 1 (60 FPS).

Oh ! my bad sounds like way above my paygrade 😅 but I am sure to go through the repo soon enough as I am new to this and see if there is a way to poll the events based on available resources. and see if it's possible

The new desynchronized context creation attribute (still in development) can help you achieve lower latency. It's not very precisely specified exactly how it behaves, but right now I think it may be either:

• front buffer rendering
• tearing allowed (e.g. DXGI_PRESENT_ALLOW_TEARING)

---

If you're interested in rendering faster than the display refresh rate, you can technically do this by using setTimeout(..., 0) instead of requestAnimationFrame. In conjunction with desynchronized: true, it might be able to achieve low latency. However, it's recommended to always use requestAnimationFrame. The browser's rendering scheduler should already achieve fairly low latency.

Thanks a lot guys! It's good news for me.
