my code still works but it says Validation Error: [ VUID-vkQueueSubmit-pWaitSemaphores-00069 ] Object 0: handle = 0x3a6cbb0000000025, type = VK_OBJECT_TYPE_SEMAPHORE; Object 1: handle = 0x21ab067e780, type = VK_OBJECT_TYPE_QUEUE; | MessageID = 0xef858864 | vkQueueSubmit(): pSubmits[0].pWaitSemaphores[0] Queue VkQueue 0x21ab067e780[] is waiting on semaphore (VkSemaphore 0x3a6cbb0000000025[]) that has no way to be signaled.

"presentInfo.swapchainCount = 0;"
It is what the message is saying
"swapchainCount must be greater than 0"

but i don't have a swapchain
it is offscreen rendering
it worked before but when i re-launched visual studio it gave this error
so what do i do?
oh wait do i not need the present?

oh yeah it works now
no errors
gentle patrol
depends on what you need to sync
