@Nealiusthere is also a registry hack you can do to make it do high priority all the time, can confirm it works well and survive updates etc

This video gives a nice demonstration using the built in game features. But you need to fly around the emitter as much as possible, approaching from different angles and ideally circling it multiple times to get accurate results. Whether or not circling an emitter is realistic in a shooting war is another matter.

I've found you can improve game performance and overall experience by setting DCS as a high priority process. I suggested to ED that they adjust the DCS install to invoke DCS as a high priority process to try and get a free performance improvement for SP and MP Strongly suspect a lot of online warping and lagging is people's machines struggling to handle the game and network comms at the same time.

It's fairly easy to disable the mods using the built in mod manager, I have no issues running the T45 or A4c mods but I do have quite a stable system and DCS install.

Free T-45 mod? Free A4c mod? There are a lot of virtual squadrons out there that offer free training and syllabus if you're looking for a guiding hand.

Agreed, my limited experience of the A2A radar down low is not positive, it may be able to pickup a high flying bomber at 20-30km. Down low it has significant clutter and fighter size targets tend to be spotted visually before you can make them out on radar. It also points the radar up by 1.5 degrees in A2A mode. I might give it another go but I rarely use it.

Chuck's guide might be a helpful illustration on Viggen radar capabilities. A2G (p149-169) and A2A modes (p168/357) https://www.mudspike.com/wp-content/uploads/guides/DCS AJS-37 Viggen Guide.pdf The radar doesn't really track things, but it allows radar fixes for navigation or deploying A2G weapons, and primitive search and radar ranging for A2A mode within visual range (0-30km). The radar scope basically gives a raw return and is optimised for ground / ship returns. Max range scale is 120km, but in my experience ships usually appear 50-90km depending on size. Scan azimuth up to 123 degrees, 3.6 degree arc and +- 10 degree elevation change possible depending on pilot control or radar mode (as per Chuck's guide). I honestly don't have much experience of the A2A radar mode as it is a pain to use. I don't recall any bug or complaints the Viggen radar is overperforming, but also unsure if anyone has looked into it in detail. Edit: Ship ranges quoted are for a typical low altitude pop up at 500m to acquire target. It is possible ships are visible further out from higher altitudes. It is also feasible to pickup out ground installations (i.e. airfields, cities, harbours) from 30-60km and individual ground targets as pixel or blob returns <30km.

This would be an incredibly handy feature for MP. Support this request.

Afaik the AI uses simplified flight models for a lot, if not all, of the aircraft. The F5e AI does some nice moves/jinks when in the gunsights last I tried, but it does also cheat with energy

First @totmacher thanks for an amazing website and resource both to analyse optimal BFM parameters and also check the simulation itself. Apologies if I have missed an answer to the question above, but as asked by Shmal is the MiG21 with normal afterburner or emergency afterburner?

If the early radar guided missiles are modelled properly their p(k) will be pretty bad, so hopefully the effect won't be too great if people use the right tactics to counter. The earlier aim7 variants are still pretty flaky on the f14.

Check out your own link to dcs.silver.ru, particularly the low speed section. Doesn't it seem odd to you, and contrary to the evidence in this thread and reviews by test pilots, that the MiG21 has an increase in sustained turn rate whereas other jets lose it in this low speed range? This is also in fairly accessible speed range and not some strange, rarely encountered edge case either. If a dogfight ends up in a grovelling 2c or 1c you could likely end up in these speed ranges. You people seem to pick weird flight models to die defending / get attached too. If you consider these extrapolations a bunch of squiggles, and don't consider flight manuals as reliable data then it is just as well you are not the one reviewing the data and making decisions on the flight model. There's been some good evidence presented here which afaik has been under review by the M3 team. Feelings don't come into it, at least not for putting the argument together for the MiG21's low speed FM to be reviewed. If you've got data to support the MiG21 having this exceptional low speed handling feel free to present it, or perhaps provide your own extrapolation of how you think the line should go? At the moment the evidence and reasonable extrapolations suggests the MiG21 is significantly overperforming at low speeds. @Hiromachiany update on the FM review, last official response on this issue was some time ago.

I assume you mean how to use the Dora external tank? You might find Chuck's guide useful "Fuel Gauge Indication Selector Left: Vorn = Front Middle: No Tank Selected Right: Hinten = Rear Note: If an external drop tank is installed, selector should be set to “HINTEN” (Rear) since drop tanks feed into the rear tank." https://www.mudspike.com/wp-content/uploads/guides/DCS FW-190D-9 Guide.pdf

PD search - Useful for absolute maximum long range searches, but trickier for SA and results not visible to pilot. RWS - Initial, potential for large search volume SA build, particularly in absence of AWACS. TWS - Detailed picture and aim54 deployment.

Seconded, would be nice to see some teaser shots. I recall it was delayed due to the SC release about a year ago?

Cool, I would not have guessed the MiG21Bis had this capability.

Lots of good points so far. When you're defensive you're leading the dance so to speak. You still have a lot of control over what is going on. Change plane, change direction, change speed, create position and gun tracking problems for your foe. The Viper tends to be better above 10k ft, so high energy spiral climbs can work well as they do in the F15. But this can be tricky to do if missiles are involved. Also as before practice practice practice, first against AI (despite their simplified flight models) and once you're good there move onto one of the dogfight servers.

Just doing some testing for a suspected bug and noticed a potential other bug related to this. It became apparent with radar off or standby and no input to the TDC range that the range indicator still operated as if the radar was on for a2g radar ranging. I'm guessing this is not correct behaviour? Or does the MiG21 do some radalt and depression angle to slant distance calculation? (though fairly sure the radalt was off as well in the testing I was doing).

Do you have any sources for your RP22 doppler filter information? Interested as I find the "techniques" of radar fascinating as a physics grad, I found a few sources on the Rp22, mostly East German and Polish operations manuals with some low level details. Also, on RCS (figures from version 2.5)

If you've got some evidence / information on the MiG21 radar I'd recommend adding it to the bug thread I'd also recommend reading some of the discussion there on the arguments for and against a range adjustment. I don't think anyone is suggesting the MiG21 shouldn't be able to shoot people in the face with the R3R, but the range seems too generous atm for that type and era of radar.

Lets be clear here indeed: 1) Comment on the new pylon ordinance selection feature as well as the various Mig21 and Viggen bugs not being fixed to help keep people informed and aware of the current situation. 2) Respond on how it was funny when the SPS feature was introduced some MiG21 pilots using landing flaps with AB during slow speed dogfights were caught unaware of this change and suffered. 3) Cue you getting involved to try to initially claim this is impossible "Even pulling to within a hair's breadth of a stall in AB at sea level will leave you too fast for the flaps to come down far enough to trip the SPS microswitches"*. Implying I don't fly the MiG21 or know what I'm talking about etc. Continued discussion from you mistakenly thinking I'm making out the SPS landing flap situation is an advantage? Some Viggen flap use comparison based on a discussion I vaguely recall. Once more trying to accuse bias, except I've submitted and supported bugs for blue and red planes to fix both advantageous and disadvantageous situations, fly all sides etc. * The landing flaps are practically fully down at about 360-380kph. It is entirely possible for people to get into this speed range during a dogfight particularly in scissors / one circle or at the top of the energy egg. Whether or not they are an advantage is debatable and I would personally avoid flaps use during dogfighting in most jets, unless they are automatic. I think you're the one hung up on this. Try not to take every comment involving the MiG21 so personally and also reading posts twice would probably help to avoid misunderstandings. The reason I'm not on DCS/CW infrequently is because I have other hobbies and groups I fly with, I'd recommend you also try some hobbies outside of DCS.

Ahh, don't let the MiG / RedFOR Mafia lead you astray. The AJ in AJ37 stands for Attack - Jakt - Strike fighter, the AJ37 has a secondary fighter role. Appreciate the server views the AJS37's role differently though as the server was primarily made on the MiG21 vs F5e battle. Some interesting comments from a Viggen pilot to consider: "In air-to-air combat the engine, RM8A, was more than likely to end up in engine stall if you even touched the throttle at some high AoA or altitudes. You could not pull more than 6 G and you had no audio warnings while at the same time the alpha meter and G meter were located ridiculously far away from each other in cockpit. You had to be aware of transonic speeds due to the steering system and so on... So, the AJS was less than a good airplane at air-to-air combat. But if you were one of the rare old dogs who had done nothing more than been flying the AJS viggen for some twenty years, you could use the lower weight of the aircraft to your benefit. The AJS actually accelerated better than the JA at most altitudes and a good pilot could outturn the JA37. The sensitive steering system also makes it my choice in low level flying, where the AJS really excelled. Still, it had no gun... In air-to-air I would pick the JA37 at any time." If you check out the turn rates for the MiG21, F5e and Viggen, well, the Viggen has some moves https://dcs.silver.ru/1,9,74,turnrate It might surprise you to know people do fight at stall speeds or below, and I observed a few that attempted deploying landings flaps (yes I was close enough to see that) with AB to suffer a surprise around the time of the SPS change. This is the difference between studying theory and doing practicals. Also no need to claim an advantage in this situation, aircraft naturally have them in real life and we must work with and against them. Unfortunately we arrive at situations in DCS were bugs or misinterpretations of the aircraft can result in an unrealistic advantage a'la the Viggen speed bug, MiG21 radar bugs etc. The bugs are well documented as you are aware having been involved in many of the discussions and even claiming erroneously that the MiG21 radar range was legitimate as it had "always been that way" and "it was due to the pulse doppler radar". Hopefully we will still be alive by the time both Viggen and MiG21 bugs are addressed.

The negative drag issue has been improved but not gone yet, I think they only ever claimed it was an initial adjustment not a fix. Hopeful the big Oct update for Viggen will include proper fixes for the speed bug. As for the MiG21 the SPS fix was good, had suspected a few were dogfighting with landing flaps and AB and saw a few dropping out of the sky when it was fixed a few months ago. The non flaps/AB related, general FM low speed handling overperformance has been reported for over a year now. If M3 are fixing things in the background I would be grateful to know what these things are, latest OB updates have been fairly sparse for the MiG21.

Been using a custom "CMDS_ALE47.lua" for F16 countermeasures since release, given the absence of a reasonable way of setting this in game provided by ED. Now I can't join servers due to having made legitimate value changes to this file and the IC check. Also bug hunting and submitting detailed bug reports used to be a lot easier when files weren't encrypted. Perhaps a rethink of anti-cheat approach? As mentioned by others before it feels like this will result in IC being disabled.
