VkCreateDevice requests unavailable features ( support for Intel ARC )

[mjtaryma]

VkCreateDevice called by RTGL is requesting features that are not supported by the Intel ARC. This causes a premature crash due to the call failing.
Those features seem to be not critical ( Disabling those features enables gzdoom-rt and prboom-plus-rt on ARC A770 ).

Here is the list:
VkPhysicalDeviceFeatures.shaderStorageImageMultisample
VkPhysicalDeviceFeatures.shaderFloat64
VkPhysicalDeviceFeatures.shaderResourceMinLod

Previous call to vkGetPhysicalDeviceFeatures2 returns properly and provides the right data to the application.
Fix options:

1. Disable those features in hard-coded list in VulkanDevice_Init.cpp
2. OR VkPhysicalDeviceFeatures obtained through vkGetPhysicalDeviceFeatures2 should be used for device creation.

Thanks for this, I made a fork with your changes and minor fixes to get CI running again (outdated VulkanSDK download URL gets 404). Action artifacts are available and this RayTracedGL1.dll works as a drop-in replacment for Half-Life Raytraced on my Arc A770.

Just debugged and disabled same features and got it working, should have checked here first 😅

Hello, I know it's been a while since the post, but I'm having trouble compiling with these fixes. Could someone provide me with RayTracedGL1.dll with these fixes?
