As inpayne has stated, most of the more modern jets are Fly-By-Wire, but in DCS the ffb effects depend on the module maker, otherwise you can use the VPforce Telemetry App to give all aircraft basic ffb effects & you can further edit what effects are felt by each aircraft & at what points the effects are felt, although this isn't as easy as changing the Rhino base's config per aircraft, it can be done. Some of the effects might not be realistic eg. the FBW f-18 when using the telem app will give ffb effects for things like weapon release, guns, ground texture on taxi/takeoff, now some of those effects might come through the stick in a fbw jet, some might not, some effects might be felt more though the seat or the aircrafts body but it definitely adds to immersion.
