Adding weight via a script limits this workaround to missions which you edited yourself. The same result could be achieved by nerfing its thrust/weight ratio via dropping the thrust numbers across all Mach bands by the same percentage. This would automatically carry over to ALL missions and campaigns. It would also be good to validate the change against player controlled PFM plane with tests like the above, otherwise over-nerfing is like putting AI on easy. If one wants simulation of course.

The glass is half full, people Yes, there are issues with some(!) AI SFMs, but isn't it cool that we have access to make changes as we see fit? Here is a table of DCS aerodynamic parameters that are used in SFM (on top of the power output per Mach band tables - those are self explanatory) from page 30 here https://forum.dcs.world/topic/97337-beginners-guide-to-dcs-world-aircraft-mods/. The location of the SFM lua file is "DCS World OpenBeta\CoreMods\aircraft\MiG-15bis\MiG-15bis.lua" and so on for other aircraft. There just two small tables to edit in the file To conclude, the part is more accessible than it may initially appear. We load up the AI Climb Test/AI Turn Test missions with our jet having identical fuel, weapon and speed settings - missions link: https://forum.dcs.world/topic/326798-ai-turn-and-climb-performance-impossible-for-a-human-aircraft/#comment-5226532 We try our best to keep up with the AI. Then exit the game, tweak the parameter that we feel is out of whack, load back in, test again. Rinse and repeat until there is a good match with our PFM plane and its AI twin. The world is our oyster Or, we could wait for ED, the second coming and the heat death of the universe

Yup. Just to make it more concrete, here is a video from my AI Mig-15 thread above. In this controlled test, my Mig-15 has the same amount of fuel and the same speed. But i just cannot keep up with AI's climb. Luckily, AI FM lua files are open for editing and even a simple nerf to the power-speed table is enough to make AI's climb more like the player's PFMed plane. Better and more in-depth edits of AI's SFM are also open to possibilities.

I can take out any AI aircraft in any Gen4 jet (guns only), most of the time it is trivially easy. Switch away from 4th generation fighters to earlier jets and the task becomes much harder in some cases. Like try fighting contemporary adversaries of F-86, Mig-21, F-4 etc in matching period aircraft. But the point is not the difficulty, it's the unrealistic flight performance of early jets vs each other (not vs Gen4 fighters)

Yes, the luas are open to us and directly control single player AI FMs! I've modified the MiG-15 AI SFM recently, same method of testing and tuning may be applied to other aircraft (see this post, use google translate):

Yeah, the aim is to convince ED -yes, but also to change stuff ourselves. ED have been working on GFM for many years, and who knows how many more years it will take. MiG-15 is over 10 years old, and its AI SFM still has all these issues. Same with MiG-21. So my point is not to wait for ED, but to take this into our own hands. The easiest way out is just to set the AI to easy. But if you want a better simulation of Phantom vs MiG-21 duel, then editing the lua table is your best bet. And, once done, the fun may last a good while -see the above

Experiment and post your result here You can get MiG-21 on 2 week trial if you don't have it already, and then just run the climb test, tweak the SFM, run it again etc. Just make sure to put it into 2nd stage afterburner when testing - if you're not familiar with the 21.

I am not even sure GFM is needed to address these issues. If ED QA testers try the simple climb and turn tests above, current SFM tables can be easily changed to address the major differences between human and AI flight envelopes. SFM tables control things like power and roll rate for different speeds. At the moment SFM table seem to have been generated from real data (which is great!), but are left at that. I am proposing to add a second stage, where SFMs are compared to human controlled PFMs (in controlled setting) for ADDITIONAL tuning.

MiG-15 and MiG-21 AI have much better climb rate at high AoA. Feel free to test them (and other AI) yourself, see these threads for an easy test that you could conduct yourself and also for some ways to mod the AI FM for closer match to human controlled planes. I'd be curious myself on what you find, I've only dug into the MiG-15 AI that does outlcimb human controlled MiG-15 in the controlled test below.

Мысли про МиГ-29 в ГС3 от реального летчика МиГ-29. Видео старое и наверное было, но для затравки так сказать

Хм. Скорее-таки баг, тк мой Ф-86 Сейбр набирает высоту примерно как и бот Сейбр. Бот Ф-5 тоже совпадает +\-. Бот МиГ-21 - вот этот точно из племени НЛО, вместе с ботом МиГ-15. В общем, не все боты равны в уфолетности. Что интересно, в 4м поколении таких явных проблем нет, проблемы именно с ранними реактивами (кроме 15 и 21го, подозреваю МиГ-19, Мираж Ф-1 и Ф-4). Пока ждем правку\разъяснение от разрабов, сделал мод чтоб немного успокоить бота МиГ-15. Просто достало, что он против меня на таком же Миг-15 по восходящей спирали от уходит до бесконечности. Про Сейбр - вообще молчу, а все ради него, понятно Грубо и на коленке, конечно, просто порезал ему тягу на низких Махах: dpdh_m = 1670, -- altitude coefficient for max thrust dpdh_f = 1670, -- altitude coefficient for AB thrust table_data = { -- M Pmax Pfor { 0.0 , 23000 , 23000 }, { 0.1 , 23000 , 23000 }, { 0.2 , 21430 , 21430 }, { 0.3 , 21040 , 21040 }, { 0.4 , 22090 , 22090 }, { 0.5 , 21490 , 21490 }, { 0.6 , 21310 , 21310 }, { 0.7 , 21400 , 21400 }, { 0.8 , 22090 , 22090 }, { 0.86, 22780 , 22780 }, { 0.9 , 23300 , 23300 }, { 0.94, 23650 , 23650 }, { 1 , 24260 , 24260 }, { 1.04, 24600 , 24600 }, { 1.1 , 25640 , 25640 }, }, -- end of table_data (DCS World OpenBeta\CoreMods\aircraft\MiG-15bis\MiG-15bis.lua ) Если тут есть спецы по СФМ, то улучшения приветствуются.

Не могу на своем МиГ-15 в наборе высоты удержаться за ботом МиГ-15 в тестовой миссии. У нас одинаковый вес, топливо, скорость - но его Роллс-Ройс сильно превосходит мой. Видео , трек и миссию прилагаю. Это мои кривые ручки или тему можно в баги? AI_test_climb_Mig15.miz AI MiG-15 climb_a.trk

Треки повторов стали чаще десинхронизироваться начиная с версии DCS World 2.9.14.8222 19.03.2025 СОХРАНЕНИЕ СОСТОЯНИЯ МИССИИ и вплоть до последней версии 2.9.16.10523. На версии 2.9.13.6818.2 все отлично. Тест - полет в простейшей миссия ганзо против ИИ бота и просмотр повтора. Начиная с версии 2.9.14, через минуту-две повтора, практически гарантированно бот начинает делать то чего не делал. Треки записываю в каждой версии новые, не переношу их с версии на версию. Вот пример трека из ДКС 2.9.16 - сначала сохранил полет как трек, потом сохранил неправильный повтор этого же полета как еще один трек. Аналогичные полеты и повторы 2.9.13 ни разу не имели рассинхрона. Su-29 desync replay of replay.trk Su-29 desync replay.trk

The "end of track fiber" problems are now solved, thank you! But! Replay tracks became much less reliable in general, starting with version DCS World RELEASE 2.9.14.8222 03/19/2025 MISSION STATE SAVE, 2 NEW CAMPAIGNS, HOTFIXES The last reliable DCS version for stable track playback was DCS World RELEASE 2.9.13.6818.2 03/05/2025 CAMPAIGNS UPDATE HOTFIX I still have 2.9.13.6818.2 and have tested all the subsequent versions, including the latest 2.9.16.10523. The simple short shingle player mission against 1 AI plane never desyncs in 2.9.13 and almost always desyncs in all versions after. A typical short track is in the attachment. Su-29 desync2.trk
