dll proxies still supported?

I'm currently using ReShade on Halo 2 Vista and am trying to find a way to use this patch with it. It's a shader patch for Nvidia cards but is implemented through it's own d3d9.dll, hence the problem. Is proxying still supported or is another method needed?

I think I figured it out. According to some things I read ReShade doesn't support proxying only DLL injection through ENBinjector. Problem is from my experience and this thread this method stopped working. Luckily I found that replacing the injector app with this one fixes it.
