My VRAM is stable, half full during tests. I suppose it is not the related with my stuttering. Thanks for info to check.

I have noticed major improvement in stuttering issue and reduced it more than a half with increase of Preload Radius. I have used to have it down on 100, and now after increase to 30000 I have got noticeable improvement. Somebody bothering with stuttering please check out.

I suffer stuttering both MT and ST. After cleanup and repair I have got still the same issue. No luck...

ED should propose some troubleshooting/update/solution for stuttering/freezes that many users have mentioned. It is not about quality, it just makes DCS unplayable right now even we have got good FPS, stuttering and freeze are worse than stable low fps. I have experienced it EVEN with all settings to OFF/LOW and after delete metasheders2 and fxo as suggested with older updates. Edit: Stutter and freeze are not VR related issue.

I have got the same, strange strong stutters that last 1-2 s and appear once per minute or even more. I do the test with all new features OFF and AA also OFF. Just to init new optimum settings - I fail.

So we might assume DCS is actually addiction issue ? Anyway horror scenario...

I have got lately the same problem, nothing helped. I did update Windows and it was the solution for me. It might be helpful tip for someone who face it.

Wings area is defined by engineer just as reference area in order to calculate things not with raw force but with coefficients It doesn't mean at all that F-18 which got CL nearly 2 can produce more lift than MiG-29 with it's CL 1.5, they use different references. Usually wing areas are 'extended' inside the fuselage - leading edge extended to root with straight line, and the same with trailing edge line. In case the aircraft have LERX... things complicate a bit. During low angle of attack LERX is aerodynamicaly invisible (if well designed ), and during high AoA the LERX induced vortex engergy is essential to produce the high lift. Moreover, lifting body issue is also important. Discussion take into account aircraft CL which is superposition of wing CL, fuselage CL, ale horizontal stabilizer CL. Regarding fuselage CL, engineers can define it for many different ways, but reference stays the same as for previously defined wing. Regarding the horizontal stabilizer CL, aerodynamic stability have big influence on the result. If aircraft is not aerodynamicaly stable, it will generate more lift (less negative lift), and if the aircraft is aerodynamicaly stable, we can expect that horizontal stabilizer will generate less lift (more negative lift). Reference here is also wing area. Very interesting thing is the dynamic lift behavior. During dynamic increase of AoA, lift measured at one value is different than during dynamic decrease of AoA, even the measurement was done at the same value of AoA. Here enters the hysteresis of lift...

I would recommend to all interested of such comparison of different aircrafts to ensure understanding the basic theory of glide flight. Just to get the things straight: maximum lift to drag ratio is a one number that allow you determine the range of glide (no wind) and is not related to aircraft mass at all. The mass have the influence just on the speed. Increase of mass will increase the optimum speed. Range will stay the same.

@DevrimI would like to ask if it is possible to share the files that are some initial version, like on the first page screenshots. The texture included shade effects and as for me looked a bit more realistic than without shading effects. I hope it is still possible.

Yes. You can open description.lua of any working MiG-29S and G liveries and compare to description.lua of MiG-29A. You will notice which files should have the letters c(Russian S) or G to make it work.

Regarding MiG-29 there is all data available in "Practical Aerodynamic of MiG-29". Russian engineers published such books for many airplanes, and such books were a great base for all the pilots that were elite and want to know the airplane like test pilot do. For example: lift coefficient changed with Mach speed as below:

If somebody would want to convert livery from A to G here is the way based on my example: You have such lines in decription.lua of your livery: livery = { {"mig29_tex1", 0 ,"mig-29_tex01_pol",false}; {"mig29_tex2", 0 ,"mig-29_tex02_pol",false}; {"mig29_tex3", 0 ,"mig-29_tex03_pol",false}; {"mig29_tex4", 0 ,"mig-29_tex04_pol",false}; {"mig29_tex5", 0 ,"mig-29_tex05_pol",false}; {"mig29_tex5_BN31", 0 ,"mig-29_tex05_pol",false}; {"mig29_tex5_BN31", 3 ,"mig-29_numbers_pol",false}; {"mig29_tex5_BN32", 0 ,"mig-29_tex05_pol",false}; {"mig29_tex5_BN32", 3 ,"mig-29_numbers_pol",false}; {"mig29_tex6", 0 ,"mig-29_tex06_pol",false}; {"mig29_tex7", 0 ,"mig-29_tex07_pol",false}; {"mig29_tex8", 0 ,"mig-29_tex08_pol",false}; {"mig29_metal", 0 ,"mig-29_metal",false}; {"mig29_nose", 0 ,"mig-29_nose_pol",false}; {"mig29_nose_BN31", 0 ,"mig-29_nose_pol",false}; {"mig29_nose_BN31", 3 ,"empty",true}; {"mig29_nose_BN32", 0 ,"mig-29_nose_pol",false}; {"mig29_nose_BN32", 3 ,"empty",true}; {"pilot_mig29_body", 0 ,"pilot_MiG",false}; {"mig29_metal", 0 ,"mig-29_metal",false}; {"su27_k36", 0, "su-27_k36_59", false}; {"mig29_parachute", 0, "parachute_paint", false}; You need to replace major 'mig29' lines for 'mig29g' as below: livery = { {"mig29g_tex1", 0 ,"mig-29_tex01_pol",false}; {"mig29g_tex2", 0 ,"mig-29_tex02_pol",false}; {"mig29g_tex3", 0 ,"mig-29_tex03_pol",false}; {"mig29g_tex4", 0 ,"mig-29_tex04_pol",false}; {"mig29g_tex5", 0 ,"mig-29_tex05_pol",false}; {"mig29g_tex5_BN31", 0 ,"mig-29_tex05_pol",false}; {"mig29g_tex5_BN31", 3 ,"mig-29_numbers_pol",false}; {"mig29g_tex5_BN32", 0 ,"mig-29_tex05_pol",false}; {"mig29_tex5_BN32", 3 ,"mig-29_numbers_pol",false}; {"mig29g_tex6", 0 ,"mig-29_tex06_pol",false}; {"mig29g_tex7", 0 ,"mig-29_tex07_pol",false}; {"mig29g_tex8", 0 ,"mig-29_tex08_pol",false}; {"mig29g_metal", 0 ,"mig-29_metal",false}; {"mig29g_nose", 0 ,"mig-29_nose_pol",false}; {"mig29g_nose_BN31", 0 ,"mig-29_nose_pol",false}; {"mig29g_nose_BN31", 3 ,"empty",true}; {"mig29g_nose_BN32", 0 ,"mig-29_nose_pol",false}; {"mig29g_nose_BN32", 3 ,"empty",true}; {"pilot_mig29_body", 0 ,"pilot_MiG",false}; {"mig29_metal", 0 ,"mig-29_metal",false}; {"su27_k36", 0, "su-27_k36_59", false}; {"mig29_parachute", 0, "parachute_paint", false}; I don't know why ED changed it lately - just a month earlier there wasn't a need to change anything.

I have released new skin based on @59th_Jack livery of the Polish Air Force MiG-29 (download here). It has got reworked camouflage, new weathering effects, and appropriate texture file of airplane numbers. It might be a great opportunity to replace the old and a bit unrealistic default skin of the Polish Air Force in DCS. During online gameplay not everybody have downloaded realistic Polish skins, default one in DCS is simply outdated and a bit less realistic. It would be great to add it to DCS core and set as default DCS skin for Poland. There was none of such Polish repaint that allow you to choose airplane tail numbers within the DCS mission editor and display it as it should - actually it was the main reason to make such universal repaint.

Few corrective actions later skin has become available here.

Few days ago I made a new stock skin based on @59th_Jack livery of the Polish Air Force MiG-29. I have reworked camouflage, added weathering effects, and created a texture file of numbers that allow you to choose airplane tail numbers within the DCS mission editor. It might be a great opportunity to replace the old and a bit unrealistic default DCS skin of the Polish AIr Force. I attach screenshot files of the new livery below. It has not been released yet.

Improvement would be appreciated not only for VR pilots. Currently advised MSAAx2+SSAAx1.5 compromise result in performance drop that sometimes is just too much for average hardware.

MiG-29 is very likely to reduce speed when you simply increase AOA for a moment. Real pilots sometimes even say that airbrake is absolutely not necessary at all on this aircraft. This intense drag increase related with increase in AOA is typical on all aircraft with LEX (leading edge extension) and even more likely on delta wing aircrafts.

I felt big difference at 2.8 update, it wasn't officially anounced, same with radar ranges corrections of other aircraft.

You are right. Historical filter was on. I didn't knew at all if such thing exist like "historical filter". Thanks for quick reply, all works now.

Hello, Lately I have noticed that when I create mission I can't select/add MiG-29A for Serbia country. I have checked file db_countries.lua placed in DCS World OpenBeta\Scripts\Database and Serbia should have MiG-29A available. For any mission task there is no MiG-29A on the list. For countries like Russia, Slovakia, Poland the MiG-29A appear on the list. I suspect that some other units might be missing on list but can't recognize it yet. Funny thing is that I can open and use my previously created mission with Serbian MiG-29A. If I change plane for another, I can't re-select MiG-29A on the list which is also strange. I did cleanup and repair of DCS World in SLOW mode and unfortunately nothing changed, just some liveries were moved to backup folder. Somebody has got any ideas ?

HI there, It would be great if we could share some information about NATO and Russia Air Force doctrine. Most of the information are top secret, anyway we have a none-top-secret source of information that indicate behaviour during air combat operation. I mean podcasts, videos, maybe some documents that were officialy uncovered. Let's make this subject a set of information like puzzle that could let us estimate big picture of tactics and strategy that might be involved into DCS flying. For very very beggining: https://www.youtube.com/watch?v=U9HdBswnoks https://omegataupodcast.net/252-red-flag/ (Red Flag is a source of good information that might be satisfying for DCS pilots) https://youtube.com/playlist?list=PLYW9PvYkTjQebdKRmtvcpGPHBiSkFxCvh (Jetstream TV series contains interception and A/G training) Best Regards, Mat

Usually static thrust parameter is the engine parameter - one engine, not all powerplant of aircraft. Regarding Thrust to Weight ratios your flight test of vertical climb is not appriopriate, as on high angle of attack, your lift to drag coefficient (L/D) may vary with different aircraft. In such test you took into account forces: weight, thrust, and you forgot about acting forces: lift and drag. If you would like to perform such test, I would suggest take-off-roll time and distance to chosen speed for example: 185 kias, it will also do not show correct numbers but will be much closer to judge T/W ratios.

Thank you !

I would like to ask if there is a way to have J-11A cockpit voice alerts language set to english and leave Su-27 with native Russian. DCS main menu settings change all to native or english and it is not a solution for me. I suppose there is a way to set it manually in some configuration file or replace chinese voice files with english ones ? Thanks in advance for help.
