Bumping this thread as I found an old version Harrier doing the climb test, and achieving a more respectable 62sec to 6000m(20 000ft): I wish there was an option to pick FM version, like with the Uh-1 where we can use old FM or updated FM.

The problem continues with the latest 2.9.20. A simple 1v1 duel with AI - my P-51 vs AI Bf-109 - desyncs very quickly. Replay attached. The other installed version 2.9.13.68180 (the last version that had good replays, also the last version before mission state save was introduced) continues to have perfect replays. I use separate SavedGames/DCS folders, so there is no interaction between the two versions. PS Did a few more 2.9.20 1v1 duels with piston and jet fighters, desync rate is something like 80-90%. I attach another set of replays. desync AI p51 replay.trk desync AI Mig29 ver2.9.20 flight.trk desync AI Mig29 ver2.9.20 replay.trk no desync AI F18 ver2.9.20 flight.trk

Можно вкратце по пунктам про главные отличия? Как я понимаю - речь не про 29й, а про ближний бой в принципе. Я представляю, что ворочать головой в реале совсем не как с Тракиром. VR ближе, но в реале не терять оппонента в задней полусфере при активном маневрировании на перегрузках 8g+ наверное трудно или невозможно. Отрицательные перегрузки о которых в симе мы не задумываемся...

Same problem in the latest version 2.9.18.12899. I've flown a quick guns only mission in Mig-29G against AI Su-27 and the AI in the replay desynced all three times that I have flown this short mission. The player's plane is still doing what it did, including landing at the end, but the AI went rogue every single time. Replays attached. The other installed version 2.9.13.68180 still has perfect replays (I use separate SavedGames/DCS folders, so there is no interaction between the two versions). desync AI Mig29 replay.trk desync AI Mig29 flight.trk

Дискорд отвратителен пмсм - это как ВЕСЬ форум ДКС свести в несколько веток. Флуд, вопрос до одной теме, 10 постов до другой теме, 3 других вопроса, ответ на первый вопрос, еще вопрос, флуд... - примерно так это все выгладит. Найти старое обсуждение по конкретной теме - опять крупицы нужных постов в тонне остальных обсуждение. Полный беспорядок, не сказать помойка.

We need an official repository with earlier versions, not a link to big Reddit thread where the actual DL link is buried somewhere. Even a simple google drive would suffice for now

Всем у кого НЕТ тензо джойстика, обязательно ставить вот эти настройки (кривые в обычном месте, у меня 20). По умолчанию стоят настройки для тензы и самолет незаметно и непонятно перетягивается и супер легко сливает энергию в вираже. У тензы очень замысловатая ступенька кривой и МЗ, для обыч джоев получается бред

Yep, the omniscient bots are indeed an urban myth in DCS. In your case you've cheated somewhat by spawning in the blind spot, but, although it is a hard thing to do, it is still possible to actually sneak up on the AI: Well, it does not stop climbing. In the test mission, it changes its pitch angle from 35deg to around 25deg and climbs at that pitch angle at around 220kmh IAS. The latter is impossible for the player, I could only maintain around 15deg iirc at that speed and alt. Anyways, most of your graphs also show the default AI Rate of Climb and Acceleration curves to be out of whack relative to the reference and the mod, for the stall to 500kph speeds.

У меня в ДКС в Вин10 и Вин11 зеленоглазый МСФФБ2 ведет себя отлично. Никаких дров и калибровок не делал никогда, plug & play. Твист не пользую, правда. Но менять его на мертвую ручку - никогда. Монстр FFBeast в планах, но он громадный, требует вкручивания в пол и прочее; Моза меньше, но тоже далеко не настольник. Других альтернатив нет просто, ВКБ и остальные пусть сами на свих пружинных палках технологии 19 века летают

I have two versions of DCS installed: 2.9.13.68180 and the most recent one. I have two separate Saved Games/DCS folders, so there is no untoward overlap between versions. I have tested all versions since 2.19.13. 2.9.13.68180 replays work perfect. Every single version after 2.9.13.68180 (i.e., every version with mid mission save functionality) results in AI desyncing in replays, even in short single player dogfights. My standard test is a dogfight between player's P-51 vs AI Bf-109. It lasts just a few minutes and always results in AI desyncing and going off script (the player's plane continues to fly like it actually flew). Example track is attached. AI desync.trk

They were testing aim-120 missile avoidance maneuvers in single player, high-g barrel roll to be precise (AI shoots missile, player avoids). Tacview was reporting around 1g when in-game readings were 6g+. Some player (Blackfyre) presented Tacview readings as proof, this was rejected by ED team's Chizh and it was subsequently checked by the player himself who concluded that Tacview's readings were indeed very unreliable. I mean this post:

Tacview is unreliable for offline as well. In fact, the error margin exceeds 100% and is morel like 400%. E.g., 6g in game was reported as 1.5g in Tacview(use google translate): I can only say that these small changes made a big difference Even beyond the simple climb tests, in actual combat, the difference is even more apparent - AI can no longer rely on spiral climbs against player's Mig-15 with equal fuel load. See the attachment I'm attaching the test missions as well I've posted videos of my (admittedly imperfect climb tests) Default: Curly's mod : MiG-15 AI Curly mod.zip AI_test_climb_Mig15.miz

Tacview is very inaccurate, with error margin up to 100%, ED don't even accept it as evidence in threads about FM. Standard replay taskbar readings are sufficient for ED, and therefore for us also. Climb rate at high pitch angle and angle of attack is not JUST about the thrust curve, it's also very much about the airframe- the lift and drag coefficients, Cymax stall coefficient and so on. Which is why I love Curly's mod of the AI Mig-15 SFM so much, he's changed most of the aerodynamics parameters in Mig-15's SFM, not just the thrust at low Mach values (like I did - before discovering his mod). Here is his mod in action, the 35deg zoom climb rate is very similar for both player and AI. I've recorded the climb to 7K as the AI changes to shallower pitch angle after this. The true zoom climb is to 6900m or there about. PS Here is a link to Curly's AI Mig-15 SFM Mod for people who might want to try it

Nice video! So, at pitch angle below 20 deg and above 500km/h the SFM and PFM have good correspondence - this is cool and finally some good news for Mig -15 SFM haha! But! In my vid, the pitch angle was about 35 deg, so both planes were losing speed, all the way to around 200km/h - and the AI had big advantage in climb rate. This kind of zoom climb is actually more reflective of actual combat, as planes do not do shallow climbs when fighting. So your vid does not seem to disprove anything with regards to combat/steep climbs for AI, but does prove that SFM and PFM do have good correspondence for shallow climbs.

Truly beautiful work! Dogfights vs another Mig and the Sabre of course now make a lot more sense, previously the AI Mig-15 was simply climbing out of trouble even against my PFM Mig-15, my Sabre was altogether reduced to running away and head ons... The mod crashed DCS for me until I removed everything but the SFM changes, maybe @Curly could have a look? Otherwise, the mod is simply supreme, it absolutely transformed my DCS Sabre
