37mm

Yes, exactly.
Half-adaptive refresh rate has worked so well for so long primarily by hamstringing CM so that it moves more gradually at a slower frame rate.
However that effect can be readily recreated just by going down to 'fast 3d Model quality' (the resultant bubble sizes were similliar IIRC).
As far as I can tell most of the '3d Model Quality' settings only effect the size of your bubble anyway (although I do notice the Vehicles/infantry start loosing their ancillary gear when you go down to faster or fastest).

I have to admit I'm seeing no effect whatsoever for low tree detail... the tree's always shake in the wind, no matter the setting or model quality. Even so, I too have it set on 'low'.... just in case.
I found that 'Best' 3d model quality only got you about an extra 100m on your bubble (on FAST Vsync) to ~420m@1080p. Although it did 'repair' most of the visual bubble on Half adaptive back to ~370m). It did this at the cost of a vast increase (sometimes an eight fold increase) in your "draw calls" & a consequent decrease to your fps rates.
As DeutschRitter, and now myself, advise the 'balanced' 3d Model quality is by far the most cost efficient setting. Although 'Improved' is also pretty cheap & (especially on half adaptive) increases your bubble size almost as significantly as 'Best'.
Keep the Texture quality on 'Best' though... I think every Modern graphics card can easily cope with that.
 
PS
Just in case anyone is unaware, you can change your 3d Model Quality setting in game with Shift+[ & Shift+].

I think I might be giving that Tank Raid a go.
Here's "De Hinderlaag" (I had a request)...
... nice scenario, but I really think BFC should have called it "The Dutch in a pickle".

Adding to DeutschRitters excellent advice, I've made a number of discoveries over the past few weeks. I thought I'd share them, in case others were also unaware of these things.
(1) "Adaptive half refresh rate", on your Nvidia profile, does give excellent & smooth gaming in almost all conditions HOWEVER it also tricks the game into thinking your system is struggling. As a result, Combat Mission will reduce the size of your high quality "visual bubble". I ran a test using the Demo, the Marines Assault scenario & a set location (the Engineer HQ).
On Balanced@1080p, I could get a 320m "bubble" around my position using FAST V-sync. At Half-adaptive refresh rate V-sync this would decrease to a little over a hundred meters (in one test I managed to get it down to 75m by using very powerful AA settings!).
This shrinkage can of course be countered by upping your 3D Model-Quality... however this will decrease your half-adaptive frame rates even further.
(2) I found it was best to turn off AA on everything... your in-game setting & your graphics card profile. Indeed I pretty much just have FAST Vsync & Triple buffering on my CM profile now. I only need AA when I'm getting "down in the trenches" & then I can use reshade to turn on my viewing effects (which come with AA) with the press of a button.
(3) I found using Hi-res mods or "movie mode" had little impact on the high quality visual bubble... maybe 20m here & there. My version 3.4.1 Reshade also had little effect on the bubble... although, strangely, I did seem to notice a visual bubble impact with 4.1.0.
(4) Screen resolution also effected the visual bubble... playing at 1800p, for me, leads to a ~220m bubble (on balanced).
(5) The in-game 'Fast' 3d Model quality setting appears to have some kind of built-in 'half-adaptive rate'. I think it's designed to keep your fps as close to 30 as possible... at least for most of the time.

I think I might be giving that Tank Raid a go.

Thanks Cpt. Miller!  I had checked out sbobovyc's thread but like you, I'm just not that experienced to want to even attempt to tackle 3D models.
@Rokossovski:  I'm working on texture mods for Syrians, among others.  Here are some screen shots of preliminary (that is, slapped together very quickly, lol) tests of some camo for African troops. I have a lot of camo patterns I'm planning for various nations/rebels/etc., and there will be some specifically for Syrians.  But the skins are separate from the uniforms, so they could all be used for Syrians.  With Cpt. Miller's mods and I'm sure a lot of other modders, you should have plenty to choose from! 

 

 

Apparently the "lack of multi-core support" is another of those "bad rep" meme's that has gotten around...
Key quote: Still, if CM2 were written over from scratch today there would be more use of other processors.  Not a ton more, but more than what we added into Engine 3.

A quick, little skirmish...
 

I've only been getting back into the "Combat Mission Community" for the past year or so but it's amazing how many times I've come across this "paid patches" or "BFC screw their customers" meme.
No matter how many times I point out an engine upgrade isn't a patch & give real-world examples of companies that drop their games after a few years the unhappy individual continues with their stubborn claim.
I like the engine upgrade system but its apparently got BFC a bad rep out there on the webs.
I have no idea what BFC are planning for CMx3 but I'd recommend an upgrade/DLC policy which tries to counter this (entirely undeserved) reputation.

I for one have no complaints at all with how you have decided to do the upgrades on all the games and how you have priced the add-ons and upgrades to the engine.
I also am impressed with CMSF 2 in that you made it work being able to load old CMSF 1 scenarios.
When I read complaints about how you are pricing and marketing games, I generally see it appears to be a customer who either is not someone that is going to spend much time with the product or its someone that thinks the world owes them things for free. ( Both of which have come from a gaming industry that teaches them that those two principles can be somewhat true).  So I have no feelings of remorse for them when they find out this company does not work on such concepts.
I also have found that I have never regretted a purchase of your games  in that I likely get about 800 hours a year of gaming entertainment with you products.
Where as, there is hardly any other game that has managed a 100 hours of my time in the whole time of ownership and many a game that has not given me 10 hours of time before I never want to see it again.
Keep up the good work and live long and prosper

Across the Canal, the CMSF1 version.
You played the game before the patch (hence why there's fences on the map).
You might be interested to know that the mission has been updated to version 2 recently.

I've just been using Windows Photo's... it come's with a "Movie-maker-lite".
Although now, thanks to these suggestions by other posters, I might try branching out.
