Advanced Ballistics (WIP)

[GieNkoV 30]

Are latitude and altitude information for Bornholm already included? If not can you enter them for Bornholm in next version?

[ruthberg 7]

So to be sure, we need v2.8.1 and the ATrag and Kestrel from the links you posted on the last page, correct?

All download links in all threads have been updated. Play withSix and Armaholic aswell.

Yes, Bornholm is fully supported (altitude, latitude and climate data).

Yup, the bug I was experiencing is fixed with the 2.8.1 hotfix, keep up the awesome work!

Did some performance testing with the latest version and the .dll

Used Ruthbergs Altis 360 mission or whatever it's name is.

Using the .50 cal I monitored the FPS while varying the amount of simultaneous projectiles in the air.

Nr. of projectiles --- FPS

0 --- 56-57

5 --- 53-54

10 -- 45

20 -- 35

Numbers are approximate only. Seems the mod will be fine performance wise during a normal fire fight, but it certainly makes an impact.

CPU used during testing was the FX-8350 running at 4,5GHz.

Edit: I just realised I used bullet path tracing, and that it might be a cause for FPS drops, so I don't know if my numbers are to be taken too seriously. Also, they are not worth much without running the same test without advanced ballistics for comparison. I might try that if I find some spare time.

Edit2: Okay, so here's the exact same test, only with advanced ballistics disabled:

0 --- 56-57

5 --- 55-56

10 -- 54-55

20 -- 48-52

Hope that someone finds this helpful, even though the test was quite simple and did not take too much of my time :)

Was bullet path tracing enabled during the second test?

[Brisse 78]

Yes, it was. I also had CBA, L_ES and JSRS2.2 enabled during both tests.

[ruthberg 7]

Here are my results (bullet path tracing disabled, i7-4770k @ 3.5 GHz).

Best case scenario (shooting 7.62 NATO into the sky):

Worst case scenario (shooting 7.62 NATO inside a town, projectiles flying near the ground):

The script I used to record the data:

if (isNil "myData" || isNil "myRecords") then {
myData = [];
myRecords = [];
for "_i" from 0 to 100 do {
	myData pushBack 0;
	myRecords pushBack 0;
};
};

_index = count AB_bulletDatabaseOccupiedIndices;
myData set [_index, (myData select _index) + diag_fps];
myRecords set [_index, (myRecords select _index) + 1];

myResults = [0];
for "_i" from 1 to 100 do {
myResults set[_i, (myData select _i) / (myRecords select _i)];
};
copyToClipboard format["%1", myResults];

Okay, cool. Looks like if I were to draw a curve with my data, then it would be slightly steeper, but there are so many variables involved so I guess it's impossible to determine the reason for that.

[ruthberg 7]

Yeah, it's hard to compare the results between different machines, but it should be good enough to get a rough idea.

[brainslush 13]

To be honest I'm a bit disappointed by the performance increase. I expected it to be more since we are talking about a VM vs. compiled C# or whatever you used. Well, this speaks for the Arma engine but I really expected it to be more significant.

I don't know how familiar you are with performance increasing programming tricks but if you want to I can have a look at it, maybe we can get a bit more out of it. But guessing from your proper plots it seems that you are quite familiar with the matter.

Another question: Is there going to be a stand alone version of AB after it was included into CSE? Not all communities want to use CSE. Don't understand me wrong, I like the features but our community sticks with AGM and so do others.

Edit: By the way your plots are changing all the time.

I've just uploaded new test charts which were created by using my usual testing setup (two 150 round magazines of 7.62 NATO). The previous charts were created firing from a vehicle which had additional event handlers on it, my fault.

AB Standalone version will continue to exist.

Yeah, sorry for that, I didn't want to spam new posts for the updated charts.

I will send you the AdvancedBallistics sqf code as zip archive via PM, if you're interested.

I don't know why the frames drop so much if you shoot a vehicle mounted .50 Cal, but I'll look into it. The new charts are properly representing the increased performance.

Most of the script execution time is now spent on processing the input/output data, that is sent/received from the extension call.

@Brisse, can you redo your tests with a rifle/machinegun? That would help a lot.

Edit: The "360 Degree Training Course" Jeep has additional event handler on it. They seem to cause the fps drops.

MXM 6.5mm

Altis 360, bullet tracing active

Nr. of projectiles --- framerate

0 --- 63

5 --- 59

10 -- 53

20 -- 40

Hi Ruthberg,

i know right now you're busy dealing with the performance issue

but i just wanna help you make the additional Ballistics Tables of these projectiles:

.408 CT

.50 BMG A-Max

.416 Barrett

338 Lapua Mag

.50 BMG M33

12.7x108mm

6.5x39mm Grendel

M118LR

MK262

AB muzzle velocity shift has been taken into account. Cells which show #### means the projectile has reached the transonic & subsonic region (beyond its max effective range, shooters are not recommended to shoot at those ranges). To see the 10 m increment tables, just click on "Table10"

i made them outta Ballistics_XLR but i checked them on JBM, Applied Ballistics, EBC, & Shooter as well, so i kinda hope you don't mind posting those tables on the first page ;)

Ruthberg, how about you include the dll path into the userconfig so people can choose their own file location? But the path right now is fine as well.

Wow, that's awesome, thank you!

@brainslush, I doubt that this is possible, but I'll look it up:

@TiborasaurusRex, I'll make those sticky if you don't mind.

[TiborasaurusRex 11]

you're welcome, Ruthberg :) sure you can make those sticky if you want ;) keep up the good work!

Personally, I hope BIS will contact you to implement all your work inside Marksmen DLC, this needs to be inside game engine to be versatile and lag-free, also this is a thing that this DLC should contain.

[Brisse 78]

I agree. If they plan to release a DLC with the name Marksman (which they do, obviously) then this is definitely the kind of functionality that should be in it.

[qantaqa1987 10]

im 100% sure it will not be in it. We get few rifles and weapon resting. :)

[Brisse 78]

That's what I'm worried about, but then again, it was the same story with VRS and Helicopters DLC, but VRS will actually be implemented with the patch they plan to release later today :)

[sttosin 67]

This has changed sniper gameplay forever. I am watching this very keenly. I have watched some of the vimeo vids and wondering is some tutorial with video is available that guides a beginner through all the gadgets, math, etc. I've read the tutorial as well.

Keep up the good work sir.

[TiborasaurusRex 11]

Hi Ruthberg :) here are some more Ballistics Tables of your projectiles:

M80

7.62x54mm

7.62x39mm

5.56x45mm

MK318

5.45x39mm

don't worry bro, all Ballistics Tables i've given you so far were made using your ammo parameters :) i converted some of your G7 drag model to G1 drag model using JBM Drag Function Conversion ;) please post these on the first page as well.

@gienkov, Brisse, sttosin: Advanced Ballistics is totally the most realistic shooting simulator i've ever seen! This is the only shooting simulator that can simulate muzzle velocity variation, spin drift, & coriolis drift. This mod should be implemented into the game engine. Is there any possible way to promote this mod to BI Developers?
