Waitable back buffers support #73

Closed abucur closed 5 years ago

abucur commented 8 years ago

Hello!

Some applications require very low input latency and I was wondering if there are plans to support IDXGISwapChain2::GetFrameLatencyWaitableObject() and allowing the applications to wait on that handle before rendering a new frame.

I imagine it doesn't fit very well with the model of EGL/GL but it would be a nice addition to the package. I think adding a new pointer type for querySurfacePointerANGLE should be sufficient for this case from an API perspective.

Hi Andrei, thanks for the request.

I believe you have been in contact with other Microsoft employees about this, who may have suggested using glFinish immediately after eglSwapBuffers. Did this suggestion help improve your latency?

abucur commented 8 years ago

Not by a lot. It seems to be a problem with my system configuration. I see latency when dragging icons on my Desktop and in the UWP low latency sample. It's not ANGLE related. Feel free to close.

Hi there! I'm closing out this issue since it's over 3 years old. If you're still interested in this feature then please consider suggesting it over on the master ANGLE repository's mailing list here: https://groups.google.com/forum/#!forum/angleproject

Thanks Austin
