Thank you so much for being someone still interested in the low level stuff! We are becoming few and far between!

[@OGLDEV]

You're welcome!

[@coreC..]

Now i've watched the previous 6 Vulkan videos in one go, i really need time to absorb all the info before continuing. There is quite a lot of preparation to be done in Vulkan compared to OpenGL. woot! For any Vulkan beginner the road to the first "Hello World Triangle" is long. This channel surely helps explaining all the objects and structures you need to get familiar with, before even able to render anything. 👍 I guess people without any OpenGL knowledge have an extra hard time learning Vulkan. Brave people..

[@OGLDEV]

Thanks and good luck!

Will you come back to OpenGL or is it a "one way ticket" to Vulcan ?

[@OGLDEV]

Sure I will! The next video is on OpenGL :-)

[@lanchanoinguyen2914]

can we choose between different display modes(immediate,fifo...etc) in opengl? Can those setup in vulkan be changed during runtime just like opengl?

[@OGLDEV]

OpenGL doesn't provide the same flexibility as Vulkan but there are various Vendor only hacks and driver extensions that provide some of the functionality. For example, NVIDIA has a mailbox mode for EGL so this is Android only. Not sure if they have the same thing for Windows.

[@lanchanoinguyen2914]

​@@OGLDEVokay sir,hope that you will soon grasp all of this vulkan knowledges and create the first triangle.

You can recreate Vulkan swapchain during runtime. In fact you have to if you want to handle window resize as you can't change swapchain size after it's created.

[@OGLDEV]

@vvgr409 True. Now that I look at the second question I feel that I misunderstood it. Most of Vulkan objects are immutable by design. So you have to prepare them upfront for later use and then the driver can optimize whatever it needs to do for the specific use case. But if you decide to support window resize events during runtime (which you don't have to - you can force a restart if the user wants to change resolution) then you will need to recreate the swapchain.

[@OGLDEV]

We need a few more videos for that. Stay tuned...
