Street Fighter V uses UE4 which currently has a compatibility problem with ReShade as I understood it.
(Some type of protection that requires a workaround as to not have the injection blocked I think it was, was working for a couple of UE4 versions actually but then broke again in newer builds of the engine and games using said newer builds.)
EDIT: A new version of ReShade (And the shader pack and the Mediator utility for managing configurations easier.) is in the works but there's no ETA yet.
(They'll probably announce version 1.1 or what it might be called when it's closer to release ready or how to say.)
And yeah many UE4 titles use a sort of launcher in the base folder that's a few hundred KB or so in size and then a main exe in the project folder (Differs in name depending on what the developer has named the project.) and in there a ./binaries/win32 or ./binaries/win64 folder path to the actual game exe.
