Excellent performance of doom on Vulkan !

So this morning I got the updated version of Doom (2016) on pc that lets me use the new Vulkan API. All I can say is WOW. I am running a fairly low-end pc, an AMD FX-6300 with 8 gig of Corsair Vengeance ram clocked at 2133Mhz. In terms of graphics card i'm running a 2013 Saffire R9 270X with 4 gig of VRam. I'm overclocking this card as in the following image from MSI afterburner.

I have most of the settings in Doom turned up to high and the anti-aliasing set to the highest level. With v-sync turned on i'm getting basically 60fps, pretty much locked at 1080p. The reason that this is surprising is that without Vulkan support I was experiencing drops to 30fps pretty regularly in this game. The V-Sync in doom is particularly aggressive and if you drop much below 60 it throttles everything back down to 30. Adaptive V-Sync isn't an option for AMD cards so I had actually just resorted to locking the game at 30 Using rivatuner. Long story short, if you are running Doom, get yourself onto VulkanRT, it's great.
