RPCS3 v0.0.3-3-632c887 Alpha

This was ingame a few weeks ago when I was able to capture these couple of clips:
https://streamable.com/ysf5j
https://streamable.com/udzcx

But something has regressed and in the current build v0.0.3-3-632c887 Alpha it gets to the menu but when trying to go ingame crashes with:

F {rsx::thread} class gl::glsl::link_exception thrown: linkage failed: 'Vertex info
-----------
0(214) : error C1008: undefined variable "diff_color"
(0) : error C2003: incompatible options for link

Attached log is for opengl with the above error.
In vulkan RPCS3 crashes as soon as you launch the game.

RPCS3 v0.0.4-6195-3fbc960c Alpha
This is ingame, seems very playable, performance could be a little better maybe.

Edit: Log file attached, sorry!

Game has heavily regressed then. Using identical settings yields 3 to 20 fps that never stables out. As well as having graphical glitches shown in screenshots. Skybox seems to be the only part having issues. Trying on other PPU and SPU settings yields worse performance. 

Maybe moving status to: In-Game would be a better representation of how it plays right now.
