YESSSSS !!

Maybe it's done before, but here is something for those who want more, infact major improvement in FPS drop when dropping CBU's. It has obviously a downside (as mentioned before OBJECT COUNT), and that you will see for yourself when applying this change. but can be improved by a couple of other params. Remember backup the file in question! Screenshots are below. If you want a video which proves it i can supply that, but shouldn't be needed. It works bigtime for at least some of the CBU's.

The file is bombs_table.lua (Lines are marked MOD THIS)

---------------------

t = {

count = 1, -- number of BLU-108 << MOD THIS

effect_count = 5, -- << AND MAYBE THIS

impulse_sigma = 20, -- Not used so far

moment_sigma = 0.0001, -- Not used so far

empty_dispenser_mass = empty_dispenser_mass,

empty_dispenser_L = empty_dispenser_L,

empty_dispenser_S = empty_dispenser_S,

empty_dispenser_I = empty_dispenser_I,

empty_dispenser_Ma = calcMa(empty_dispenser_I, empty_dispenser_L, empty_dispenser_S, 400),

empty_dispenser_Mw = calcMw(empty_dispenser_I, empty_dispenser_L, empty_dispenser_S),

panel_mass = panel_mass,

panel_L = panel_L,

panel_S = panel_S,

panel_I = panel_I,

panel_Ma = calcMa(panel_I, panel_L, panel_S, 400),

panel_Mw = calcMw(panel_I, panel_L, panel_S),

--Ma = 0.900985

--Mw = 1.675494

-- Release time delays for each group of BLU-108

timeDelayFirstGroup = 0.09, -- << MOD THIS

timeDelaySecondGroup = 0.16, -- << MOD THIS

Hey

what is your system and how much fps did you gain after this mod ?

Will try this soon.

Thanks !

I have a i7 920 at 3.8 GHz (most of the time), a HD-5850 stock speed, 6 GB mem.

More than enough actually. But listen up! This mod doesn't increase the overall FPS (max FPS). It wasn't the intention either with this mod as i have enough of that even on my system. What IS important for the whole sim is to not get sudden major drops in my opinion. What i got with this mod in my particular test which was to view the explosion from a distance and before the mod i had 48 -> 15 FPS!!! now i got 48 -> 36 (That is with that exact cluster config) and that is consistent!! So hope you other guys get a direction to make this sim more FPS consistent. Please do research on this even if we have to do compromises.

EDIT: I forgot to mention that i dropped the CBU's on a line of 6 trucks on Batumi airstrip. Obviously with this mod the CBU is less efficient. But i think this is one of the few ways to lessen the drop in FPS in this particular case. Anyway it all comes down to the amount of objects which explodes/ catch fire at the same time. If the bombfragments explodes with a little more timedelay between will also lessen the drop.

Another change i tried was on the SAM SA-15 Tor 9A331's warhead properties. I did the following in the warheads.lua file:

function simple_aa_warhead(power) -- By Saint << THIS ONE ONLY

local res = {};

res.mass = 0.002*power; --old explosion damage effect << MAKES MISSILE WEAKER AND THE EXPLOSION EFFECT IS LESS VISUALLY EQUALS LESS FPS DROP

res.expl_mass = 0.002*power; -- << MAKES MISSILE WEAKER AND THE EXPLOSION EFFECT IS LESS VISUALLY EQUALS LESS FPS DROP

res.other_factors = {1, 1, 1};

res.obj_factors = {1, 1};

res.concrete_factors = {1, 1, 1};

res.cumulative_factor = 0;

res.concrete_obj_factor = 0.0;

res.cumulative_thickness = 0.0;

calcPiercingMass(res)

return res;

end

Set up a simple mission with a couple of those units on ground, then fly over with let say the Black Shark and watch in F2 view. Watch the FPS when it get hit. Also note that explosion effect lessens considerably. This is a way to better survive SAM attacks too for those who need that :-)

But this isn't exactly a nice way to fix FPS hits though. The explosion effects only i think are compiled into the FXO files so isn't easy to modify unless someone finds any params which works
