Su-25T DIRCM suddenly became almost 0 effective. Why?

[Maverick Su-35S]

Hi,

          Playing DCS since KA-50 (almost 2 decades ago) I have witnessed the foreseen and the unforeseen. Now, I know that the DIRCM is basically a system designed to spot the plume of missiles within a given FOV and interpret them as real missiles or not within some given false positive error. It's purpose was to detect IR missiles although I doubt that it's able to differentiate between radar or IR missile in reality simply because it looks for a plume pattern left behind by any missile. So it basically warns you about it. After detecting that a missile is incoming, a rapidly rotating laser with a given divergence and beam intensity will eventually pass over the IR missile's seeker head, rapidly and repeatedly heating it up, up to the point of making it become completely unable to distinguish any heat signature anymore, because IR missile's seekers are highly cooled to be able to track heat targets better. The cooler the seeker, the better the lock, the hotter the seeker, the weaker the lock. That's why IR missiles are so limited in range..., not because they can't reach far. Just look at how now the IRIS-T is modeled in DCS. AT LAST..., after arguing so many times with so much logic and personal proof years behind, everyone was laughing at me until they found out that I was right, that missiles should have much more reduced drag than they had and so now we can see the IRIS-T, with better CD vs AOA tables implemented, that it has greater flight range than an AIM-120C once had (years ago). BRAVO! You guys finally found out what I was saying back then about the too high AA missiles drag at low AoA and too low drag at high AoA...! So, back to the subject, the faster a missile will fly through the air, at a greater rate it's seeker will heat up, because these are the laws of physics. So, even if an IR SAM missile can travel even past 10km down range, say... a MIM-72 Chapparal missile or IRIS-T, it's seeker will heat up in less than 4km high enough to lose the track on the locked heat source.

The DIRCM does just that, it heats the incoming missile's seeker at a fast rate. Basically, if a missile is close enough to a DIRCM equipped aircraft, let's say less than 1km away, the DIRCM will first lose some time to react and start pointing the laser in repeated motions over the missile's seeker and missile will be close enough to not loose the lock on the heat source before it's seeker is hot enough. At least, that's how I find it pretty simple and logic to see. From too close, no DIRCM will be able to stop any IR missiles due to those key details. From further away, a function of time will greatly reduce an IR missile's PK without the use of any flares..., just simply because the chance of losing lock from random factors will occur.

With basically a function of atmospheric temperature, missile speed and time of DIRCM actively heating a missile's seeker, there is a range between the launch site and the target after which that missile will lose lock 100% of times. Basically the PK becomes ZERO for good!

I don't know what happened after X latest update, but one year ago I could have more than 90% of the missiles that were coming from the aft hemisphere of my Su-25T go by my plane without hits and today almost 0% of those missiles do that anymore. Now, with or without DIRCM, from far or from close, when an IR missile is coming for the Su-25T, it hits it like the DIRCM doesn't exist. Ah..., and by the way, in the past the DIRCM was only affecting IR SAM missiles, AA IR missiles were 0% affected by the DIRCM anyway. Now even the IR SAM missiles are not affected by the DIRCM? What is the new logic now?

Thanks!
