-- VulkanMod Device Report --
Device: NVIDIA GeForce GT 740
Vulkan Version: 1.4.341
Unsupported extension: [VK_KHR_dynamic_rendering]
The VK_KHR_dynamic_rendering extension isn't supported on the 470xx NVIDIA proprietary driver. The exact Vulkan version the driver is stuck to is 1.2.175 whereas this extension was added in the version 1.2.197.
The GPU isn't limited, the driver is and using the nouveau driver isn't possible at it doesn't support reclocking, means it can't run the GPU at full speed. Even though NVK and the GPU supports the latest Vulkan 1.2 specification.
This can be fixed by removing the use of this extension, or if the work is immense, it can be clearly stated in the README and on the mod platforms that the exact version required minimum is 1.2.197, though this can be higher as I can't see what else it checks before crashing.
Thanks for reading this!
