I have a non Vulcan GPU how do I get RPCS3 to work

I have a Radeon 6670.
I know it's an old GPU but I mainly use consoles for newer games so haven't upgraded.
Anyway I should be able to use Opengl with it.
I downloaded the latest RPCS3 but it won't allow me to even start it as I don't have Vulcan and I don't have the vulcan-1.dll so it just won't work.
I thought RPCS3 was supposed to support both OpenGL and Vulcan.
I wouldn't have bothered downloading it at all if I thought a Vulkan GPU was a minimum requirement.
How the heck do I get it to work if I don't have a Vulkan GPU?
It says on your page that Opengl is supported but the emulator won't even bloody open for me.

You're supposed to have vulkan-1.dll even if you don't have a GPU that supports Vulkan
You can try to manually install Vulkan Run-Time: https://vulkan.lunarg.com/sdk/home#sdk/d...untime.exe

Thanks that's definitely the way to get it working.
I downloaded that runtime yesterday and it opened up then.
So I tried out Bionic Commando Rearmed 2 and when I got into the gameplay all the textures were blurred and frame rate was a bit jerky and music skipping 
I think a better GPU than mine is required to get anything remotely playable.
It clearly wasn't rendering textures properly.
Bionic Commando Rearmed 2 should not be a demanding game yet it looks blurry as heck and runs too jerky.
I'll use it again if and when I get a better GPU and more ram 
Core i5 2500k 3.3ghz is an ok processor still I reckon.
It's my 6670 and 4gb ram that are the issue here.
