Hi, Rico!
About both versions of your "Guderian break through Sedan", I first asked myself the same question as
Slaphappypappy.
Answer in
Status/Scenario Attributes ---> LOS Unlimited in the first version, LOS set to 12 hexes in the second.
A HUGE difference as to the lag problem.
I didn't take the time to edit both versions to compare them in detail.
In particular to know the French set up hexes & any programmed orders given to the French units when managed by the AI (if AI Attitude is set to HOLD).
See
Editor,
OOB/Modify Unit,
UNIT Attributes/
AI Special Command(*) ---> ATTACK, DEFEND, HEX (X,Y).
I played version # 1 (Unlimited LOS) with Difficulty set to Very Hard.
Result:

German Minor Victory.
Bravo Rico, an excellent challenge because the
slightest mistake costs the chance of a major victory!
[Please, see picture below: Units B & C]

Some pleasant surprises. On four of the five fortified hexes, two were 'conquered' with Broken+DM units during their Rout Phase!
I didn't imagine it was possible! Note: They were adjacent, or distant from 1 hex, to the empty fortification where they finally would be safe.
[Picture below: Unit A]

But a great frustration, too. That of not seeing an automatic centering of the screen on the targeted hexes when OBA lands.
Master Peter, help us out of pity! We want to know live what happens to all our poor little digital pawns!

A day almost full to let the CPU
(**) lag as a great one. Just to see what could happen.
Not to mention a lot of backups, meanwhile.
No no, I ain't sadomasochistic!
Just stubborn.
Yesterday, Friday, I've started a game with version # 2 (LOS: 12 hexes).
First observation: the first three rounds of play in less than 30 minutes.
No dead time. I'm just very, very cautious in deployments, shots and moves.
Perfect fluidity of the game as a user!
I know I will finish the game in about an hour this weekend.
Very nice!
Total: one hour and a half for a really exciting scenario, even if I don't necessarily manage to do better than the first time.
I'm already thinking of a third game where the LOS would be set at 20 hexes.
Why?
-
Respect for historicity.
[8D] The spring of 1940 was marked by good weather, after a harsh winter.
The visibility should be excellent (20 hexes = 1 kilometre at the game scale) without being absolute (i.e. Unlimited).
Enough for the MMG and HMG (range up to 16 hexes, unless I'm mistaken) to 'express their capabilities' at normal range, and even a little beyond.
Same thing for the OBA and the on-map artillery.
Question to Peter: beyond this limit of 20 hexes plus or minus 50% depending on the season, the time of day, etc.
why not offer a kind of Close Air Support even more random(ly) than the OBA in its first way?
-
Respect for the playability.
Need to conciliate two constraints: realism (see above) and capacity of calculation.
Don't want to wait (or even know) quantum computers for the gamers!
I want to see the effect of LOS from 12 to 20 hexes, by simply testing a precise tuning.

Surely a little maniac!
-
Comfort for the players.
To adopt a standard description of scenario (as You, Big Ivan and others already do) without this being too rigid but with the systematic and
complete mention of the
At Start/
Scenario Configuration & the
Scenario Attributes as well as their recommanded margin of variation (when using the
Editor).
Something like "Best played on ... SIDE / with LOS: ... hexes / with RULE: ... / with MOD: ... / etc."
(John Tiller's Campaign Series fondly remembered)
[&o] Thank You for your great creativity,
And Congratulations again to
Peter for his Big Game.

(*) I think there is something very powerful behind that feature but still have the impression, without being able to verify it, that it isn't
exploited enough by the creators of scenarios.
I tried to use it in my "CB002 - Thunder over Boislonde BR" (German AI = HOLD) and was rather satisfied during the tests.
I dream of an AI that can also handle scheduled orders like: ON TURN # ; ATTACK HEX (X,Y)!
But these questions also are for Peter...
