Hello @PhonicUK, please retest with mesa 18.1+ and llvm 7+.
Updating resolves the issue. Pardon me not reading the prereqs :)
I have the same issue, using mesa 18.1.6 on Proton 3.7-3 and 3.7-5 beta, with the steam stable and beta clients
Solus 3.9999 (64bit)
Kernel Version: 4.18.5-90
X.Org Intel Ivybridge HD 3000 i915
Specs:

Edit: just notices kisak_valve recommended to use llvm 7+, most recent available in my distro us 6.0.1
Hello @drshroomy, the vulkan implementation for Intel/Ivybridge is incomplete and dxvk is expected to have trouble with that chipset. You may see better results by adding PROTON_USE_WINED3D11=1 %command% to the game's launch options.
