Well for me, FPS regularily drop below 60 in TDM, and I have quite a decent system (i7 3770k, AMD Rx480, 16GB Ram), but then again I'm playing on Linux which may be a problem. Also just because FPS skyrocket in certain areas doesn't really mean anything if the average FPS isn't anywhere near that. I also know that Vulkan isn't a magic bullet and bam! 500 more FPS everywhere you look. No, but it may just help enough to raise average FPS to or above a stable 60. And yes, it really should be an option, should anyone decide to take a look at implementing this, so that the game stays compatible with older hardware, but newer hardware could still take advantage of Vulkan.
