SwapChain Creation Failure

[MathewBensonCode]

The capabilities structure return by the vkGetPhysicalDeviceSurfaceCapabilitiesKHR method return Zero(0) for the value of maxImageCount when there is not limit to the number of images.

Therefore the clamp method on line 1067 of VukanDevice.cpp fails.

@MathewBensonCode I'm curious here -
what is your device spec to have maxImageCout equals to zero ! and what is the minImageCount in your case -
because that sounds like a special case of config

[MathewBensonCode]

I have an amd apu, but also seen this on intel integrated gpu. the API states that if the maxImageCount is returned as zero it means there is not specific limit. So when we try to clamp between min and max the clamp method throws an error because max is zero.

I see,

that means some hardwares don't specify an explicit limit for the maxImageCount -
so 0 here means defined limit, but we are still constraint by the GPU memory. Make sense !

So we need to rethink the clamping approach by considering that maxImageCount range from [0.... X[ value

Thanks for spotting this - One API but : different hardwares , different behaviour. ==> Welcome to GPU world !
