WWE 2k14 - Slowdown and crashes

Hey all, been trying to emulate this game as I have some fond memories of it. 

When I launch the game using openGL as a renderer, it will often freeze when compiling PPU shaders.
 If I switch to Vulkan, the game will run, and in the menus and such everything will be fine. As soon as I start a match though, I get intense slowdown to where it's unplayable. If I continue trying to play, the game might just freeze anyway. Some textures like skin textures also show up as a solid red colour for some reason, not sure why that is. 

I've tried copying settings I've seen online, from people on less powerful hardware but no dice. Any ideas please? 

Thanks

Quick update, I copied these settings and it runs better and doesn't crash, but it's still slow and unplayable so I'd still appreciate any help

Can provide an updated log file if it would help, just don't really know what settings to tweak to try get better performance.
