There is no need to use ReShade to have SweetFX in Black Desert in 32bit or 64bit
You can copy the SweetFX files directly in BIN & BIN64 directories (change the d3d9.dll, d3d9.fx, dxgi.dll & dxgi.fx for the 64 bit versions) and it works perfectly
I put a small guide together @ BDOtome (the guys working on English Patcher and guides for BDO KR & JP)

along with relevant file downloads to basically make the process as fool proof as possible
