ANY ONE ELSE HAVE INVISIBLE MOBS FOR SECONDS AT A TIME?

Problems with direct x 12
I don't know what's causing this issue and this only occurred after the recent patch with the so-called improvements made to graphical settings direct x 11 loads faster. But it stutters on frame rates so badly it is like a scratched Busta Rhymes cd! So I was like hey I'm going to try Direct x 12 or Vulkan and yes it runs smoother. Still, it takes no joke 45 seconds for me to see enemies THEYRE INVISIBLE so ill be playing a map and get killed by an enemies mob that's completely invisible then I sit there waiting for the shaders to finally catch up just to see what i was trying to kill in the first place happily teabagging me senseless now as far as Vulkan goes? before this patch? (3.24 and every patch before this) Vulkan direct x 11 and dx 12 worked great but now Vulkan takes no lie 5 min to get off the loading screen! I don't know if anyone else is having this issue. But I hope in the future it gets fixed cause its not only annoying but effects game play
