[Direct X 11] How to disable Vsync in this example?

[AlTech]

Hi guys,

So i'm following along with this example app and I want to remove the Vsync in it.

 

It's  using Vsync and capping the FPS at 60fps. I don't like that so, how can I remove that?

 

Thanks .

 

 

I've tried many things and I can't seem to disable Vsync in it.

Huh, I never thought I'd be able to use matrices for coding

[trag1c]

HRESULT hr = m_swapChain->Present1(1, 0, &parameters);

The very first parameter of IDXGISwapChain1::Present is the sync interval. 0 presents immediately, 1-4 synconizes presentation after the nth vertical blank. So change the first parameter to 0 and it presents as fast as it can without vertical synchronization.

Huh, I never thought I'd be able to use matrices for coding

Any 3D or 2D graphics heavily use linear algebra and vector mathematics. Really anything that involves a 3D space is going to be using matrices, vectors and quaternions. Games and graphics would simply be non existent without it.

I'd say I'm glad I took it but I was forced to

It still only shows vsync though and is capped at 60fps.

Odd. They must some else limiting the frame rate in the application. It's probably due to the fact that this sample code is intended for windows store. If this were simply a plain old Win32 window application my suggestion would work with disabling vsync for Direct3D 11.

Do you know any good guides for Direct X or any good tutorials on how to make Win32 Direct X programs?

Rastertek.com is a decent one. The only caveat is that the tutorials are its using older d3d11 apis and older xnamath. These how ever are easy to overcome with a little bit of googling. 

 

I personally like a good book so another recommandation would be practical rendering and computation with direct3d 11 by Jason Zink. Or 3d game programming with directx 11 by Frank D Luna.

I'm gonna try to buy those books. Thanks .

 

I'd love to learn more about Direct X 11 and 12.

If by any chance you also want to learn opengl I recommend http://learnopengl.com/
