If you look in your cfs3configdatabase file located in the root directory of your OFF install you can see all the settings for each of the five different levels. For example,


//////////////////////////////////////////////
//
// Visibility
//
//////////////////////////////////////////////
// 40 miles
PropertySet = "Max Visibility 1"
BackClipDist = 64374
FogStartDist = 64374
break

// 50 miles
PropertySet = "Max Visibility 2"
BackClipDist = 80467
FogStartDist = 80467
break

// 60 miles
PropertySet = "Max Visibility 3"
BackClipDist = 96561
FogStartDist = 96561
break

// 70 miles
PropertySet = "Max Visibility 4"
BackClipDist = 112654
FogStartDist = 112654
break

// 80 miles
PropertySet = "Max Visibility 5"
BackClipDist = 128748
FogStartDist = 128748

Thanks for the advice chaps, will test this later

The sawtooth effect is a lack of enough video memory had it happen to me twice, first was in Phase II was running ( cat's pajamas then ) a factory overclocked 8600 complete with Zalman fan 256mb DDR3

Great picture, just don't move your head. . . Put in a much tamer 8600 512mb DDR2, the picture wasn't as chrisp, but the Jaggies were gone.

Next time was a GTX260 896mb DDR3 Couldn't afford more card. So I just moved my head slower, that worked most times, except in combat

Now a GTX480 1500mb DDR5. . Think I'll never see them again

In OFF Phase 3 (Between and Hell and "Hat in the Ring!"):

Scenery slider increases the density of all scenery objects, trees, houses, etc. i.e. more of them and more dense patches. They don't go further out from slider 4 to 5. Between 1-4 it does mean they go further out to the horizon.

If you do not see a difference leave it on 4 of course. There is just a few percent extra 8% or something more 4 to 5.
Different people look for different things.

Terrain slider higher resolution tiles to further out- CFS3 uses rings of detail basically. Often looking directly down you will see super high res etc at higher settings.

Note they are totally different to CFS3.

I'm running a GTX 570.. can run most stuff more or less maxed out.. but apparently not in this title. Testing now!

Polovski:
Thank you. This helps in setting the sliders and what they do per FPS cost.

Off hand I'd say you can, if you check out the home page it says 1024mb of video memory is recommended when running wide open. It works for my GTX480, but I'm running a plain vanilla OFF

I've always said I'm doing the testing of the mods, but there was no proof till today

Well, if I stick the terrain detail up more than 3 I get that really bad jaggy tearing.. not good, so had to put it back to 3..

I say did you try lessening the Object density in workshop then bring the slider up checking your FPS along the way
