Not to sure where you're going with this... but most competitive LANs/tournaments enforce a GUI-config rule which means that players can only use settings which are available in the GUI settings for the game. In most cases "promods" are created with this in mind for elite players to compete at the highest level. This has been seen in ET, BF2, Q3, Q4, Painkiller and the list goes on and on.
I can speak on behalf of [20ID] when I say that none of us use anything out of the ordinary. We don't use zoom scripts, hand scripts, double-jump scripts, bright skins, spiked models, white textures, modified smoke, excessive gamma levels or anything to give us any sort of advantage.
I went through my config and found a few minor non-GUI "enhancements".
- cl_locknetfps 1 -- I think this is the default though... I know a lot of people have it disabled
- A small alias which switches to hand 2 when I am shooting and hand 3 when I am not (so I know what gun I'm carrying)
- A small alias so I can toggle netgraph with a single key
- A small alias to drop a large ammo box before dropping my hopper (so the paint doesn't get lost in the hopped when I drop it)
- Misc. recon and funname binds (no LOC stuff though)
- flagstatus, nextspawn and topspeed binds
Some [20ID] members may be using
r_oldmodels 1 out of preference, but I don't think many are. DirtyTaco and BoB probably have keys bound to
"say lmfao", but that's a different story. Even if you added up all of these
"advantages" together, it still wouldn't amount to the advantage that the
3D sound system provides. Too bad I cannot benefit from this in Linux.
Edit: Everyone [20ID] member except me uses a different
fov setting. I'm pretty sure I'm the only one that uses 90. (But I use 110 or so in every other game).
