Handling windowed GSync properly when multiple windows are drawn from the same thread

[Zeblote]

I’ll try to summarize the situation:

• Single-threaded application
• Owns multiple windows, has a IDXGISwapChain for each
• Every frame it draws to each window and calls Present() in a row
• GSync is enabled for windowed mode and for the application

Now this is the current result:

The framerate of the application is locked to (desktop refresh rate)/(#windows) as GSync will block on every Present() call!

Am I missing an obvious way to only use GSync for the last window that is drawn?
Is this a solvable problem at all?

Thanks!

Well. It appears this forum is dead.

That’s really unfortunate, as there seems to be ZERO documentation on g-sync around…
