I haven't done any A2G in the Viper in a long time, so I'm in the process of trying to relearn it.
When the Viper is in A2G mode with CCRP selected I was under the impression the TGP was meant to be slaved to the current steerpoint. However, when I was doing a mission just now the TGP was not fixed at a specific point, it was moving somewhat. If I swapped steerpoints the TGP moved between different areas, but continued to move somewhat. If I slew the cursor, I can point track on the ground and then cursor zero back to the steerpoint, but this again has some movement.
Last time I tried it sometime last year, the TGP would be rock steady on the steerpoint, has the process changed in an update?
