Sure you want to open that can of worms? Success in tasks in PnP D&D is to a high degree influenced and determined by your meta-game skills, not your ability to immerse in a role or roleplay (I'm confused by the definitions at this point..). Importance of meta-game aspects is not a good divider to non-RPGs and true RPGs, since meta-game is outside the roleplaying aspects of the game.
The short answer is that mental and social faculties are part and parcel of role-playing, so what is commonly called "metagaming"* in the context of role-playing games, is often simply "gaming."
Being aware of the game as game, and applying player experience (rather than attempting to limit to "only what the character knows") is safely within the umbrella of activities that constitute role-playing. Again, it is important to remember that "role assumption" and "role immersion" are not the whole of or synonyms for "role-playing" (in this context).
Physical faculties are not part and parcel of role-playing, so if they have significant importance to how your character's actions are performed, the video game falls into the "action" category.
Players meta-game skills (for ex the ability to position miniatures in PnP D&D or the ability to punch mouse in CRPGs) is separate from the games inner reality, which is the more important divider to true RPGs and what some would call RPG simulators.
If right clicking the mouse button is used to initiate an attack (possibly choosing from hot-keyed commands for different attacks or a drop-down menu), that's no different than a player sitting at a table telling the DM "I attack [by such-and-such attack form]" This doesn't fall under the "action" category, and would be fine as an example of computer interface used to play an "actual" role-playing game combat.
If, however, you must perform some kind of physical flourish with the mouse (or joystick, etc.) to get a certain attack to function (think special moves in video games like Street Fighter II), and/or must aim your attack accurately using the physical input and GUI in order to target the opponent and certain body parts, you are playing an action game, not a role-playing game.**
*We should be careful if we are going to introduce "metagaming" as a term in this discussion, because it is often thought of as a synonym for cheating in a role-playing game (because role-playing is being used as a synonym for role assumption or role immersion). In my opinion, the only "metagaming" that is cheating in a role-playing game is when the players peek at the DM's map, notes, etc. and use that knowledge to their advantage.
**Yes, this may very well call into question to what extent LARPs are actually role-playing games. I suggest we leave that can of worms alone and stay focused on video games.
