Exclamation FPS Tweaks/MODs

First thing i noticed:

modellod.txt file now uses 1.000.000 meters for LOD high to low detail switches.
1.12 used 100.000 meter and that was already eating to much cpu cycles for nothing (you dont see LOD details so far out) so
no reason to calculate them in such detail....
community changed it back in days to 5.000 or 10.000 meters. (modellod fix on ****************).

Why they put 1million meters there now ..i dont know.

next..

LOD land in graphics.cfg is standart at 30.000 - 50.000 .....this is very optimistic considering even high-machine users already complain about low FPS.

next thing is, that farclip in graphics.cfg is 140.000... also bit high and can be lowered.

Minor things, which can be changed for improved easily ... (already noticeable fps boosts achieved in tests)
.
.
.


further test in progress......

PS: but A few things are really nice

Fps tweak ideas

I've made the following 3 changes which lets me run medium details 4xAA/AF 1920x1200 and get
more than 80 fps in the F-15 quick mission zoomed out. It is not always perfect, but for me
it makes the game look a lot better and smoother. This is nothing official, just my own
personal ideas on how to improve performance.

My computer specs are: xp32, 4gig ram, E8400 c2d and HD4870 512 MB


Step 1: Edit original "Config/Graphics.cfg":
Code:
    Medium
    {
	    near_clip = 0.2;
	    middle_clip = 5;
	    far_clip = 140000;

        structures = {40, 4000};
        trees = {1000, 6000};
        dynamic = {300, 20000};
        objects = {3000, 80000};
        mirage = {3000, 20000};
        surface = {14000, 80000};
        lights = {100, 30000};

        lodMult = 1.5;
        lodAdd = 0;
    }
to this:
Code:
    Medium
    {
	    near_clip = 0.2;
	    middle_clip = 5;
	    far_clip = 120000;

        structures = {25, 3000};
        trees = {1000, 6000};
        dynamic = {300, 5000};
        objects = {3000, 40000};
        mirage = {3000, 15000};
        surface = {5000, 15000};
        lights = {100, 30000};

        lodMult = 1.5;
        lodAdd = 0;
    }


Step 2: Edit original "Config/Graphics.cfg":
Code:
LandLodDistances
{
    LandDay
    {
        L01 = 30000;
        L12 = 50000;
    }
    LandNight
    {
        L01 = 20000;
        L12 = 40000;
    }

   .
   .
   .

}

OldLandNoise
{
    perSquare = 5;
    perSquare2 = 150;
    front = 1000;
    back = 10000;
    top = 2500;
    map_high = 20000;
    bottom = 2000;
    noisemax = 0.5;
    noisemin = 0.1;
}
to this:
Code:
LandLodDistances
{
    LandDay
    {
        L01 = 8000;
        L12 = 40000;
    }
    LandNight
    {
        L01 = 8000;
        L12 = 40000;
    }

    .
    .
    .

}

OldLandNoise
{
    perSquare = 5;
    perSquare2 = 150;
    front = 1000;
    back = 22500;
    top = 2500;
    map_high = 20000;
    bottom = 2000;
    noisemax = 0.5;
    noisemin = 0.1;
}


Step 3:

Replace your Bazar/ModelLOD.txt file by 104_route's file : http://forums.eagle.ru/attachment.ph...2&d=1269732322
(old fc1 trick which I cannot see any diff from)




Watch the beauty of FC2

Good point, but without i fear you will fail enjoying redflag-big scenarios.
So we have to find a way what is allowed (legal) and what definitly can not be considered to be changed. As far as i hear, this can be done in the integrity checking system.

You cannot integrity check graphics.cfg, then nobody can join because everyone uses different settings for it. Some use high details, some low etc

Except scenes and civ traffic I think, that is hardcoded in the mission.

Yes but you can only integrity check entire files, not specific lines in a file

Yes it is a catch 22. There are some bad things we all know we can do the graphics.cfg and modelod.txt file.

It would be a far strectch to have everyone use the same graphics settings!

Sorry A.S for the slight hijack of the thread.

You can however force modellod.
Turns out it barely affected my tweak anyway, so I wouldnt mind that.
