Problems I have encountered using voice chat feature on OB 2.9 and 2.8: 1. Me and my friend can hear eachother in room mode but not in radio mode(while transmit& receive ,red&green square-indicator IS working properly). We only hear static noise for half second.Even if we are parked next to eachother. Then we change server and it works. Conclusion, sometimes it works, sometimes it doesn't work. 2. After some time chatting in private room (room mode) I begin to hear my own voice with delay and some static in background. Hearing my delayed voice back makes it very difficult to talk except short answers like yes,no, numbers,etc 3. In radio mode I can hear other people talking intermittently (or breathing, typing keyboard, clicking,etc) while sqare-indicator remains yellow ( means no one transmiting on the radio). 4. Sometimes me and my friend can't see/find eachother in room mode while on same server.

On my pc with reprojection on using MT I can't play because I get 15 FPS. Without it I am between 60-90 FPS. With ST reprojection works nice but I have less FPS(around 35-55) with my settings which are the same for MT. I have really irritating stuttering but without FPS drop. I know this sound wrong but it is true. I look at FPS counter and it is solid 60 FPS on Mt but menus are lagging, jumping, stuttering, aircraft and terrain significantly less stuttering but still present especially on populated servers. This doesn't happen on ST and it didn't happen on MT when I had 1080ti. Now I have 6950xt and I have this problem in MT.

Is it normal that upscaling option is unavailable (grayed-out) in 2.9 ST version? Both case with Anti-Aliasing on and off.

Try turning off reprojection. In my case reprojection makes it worse because it reprojects at very low FPS even if I have 90 FPS initially. In addition to that UI elements are twitching and stutter very bad even if FPS are high. It feels like frames are periodically lagging on one eye. My suggestion: Turn reprojection off Lower settings Monitor FPS to see what FPS you get Then again reduce or increase settings to be above your VR headset frequency so you can have smooth frames most of the time Or... Switch to ST version with FPS setting above half of the VR headset frequency Example. I can't get 90fps but I can get 70-80 FPS, then I switch my headset to work at 60 Hz, then I have more than 60 Hz in the background but display stays at 60 Hz, then if frames drop below 60hz turn on reprojection. This is for ST version only. I turn reprojection through steam vr app inside of VR, you can't do in on 2d screen, no option in 2d. I think my open XR tool doesn't work for reprojection yet, so I use steam. That's what I would do

Problem is still there on DCS 2.9.0.46801 Open Beta. It is very irritating. MT version now starts by default, too bad ST version doesnt have upscaling enabled.

I have been playing MT and ST back and forth and I would like to conclude that post title is now wrong. Both MT and ST are playable but I have issues with MT in the menus mostly. In game effect is now negligible although my DCS play is 90% flying and very little weapon use. Only problem now is that the menu section of DCS MT is extremely irritating to my brain-eyes because of this weird effect. MT feels smoother than ST. Msaa seems to be working now. Reprojection still doesnt work in ST...

I have some news. Updated windows. Ran both DCS MT and ST same settings same scenario. Got no FPS drop over Kobuleti. No problems while flying. p51-freeflight over Poti. -MT 90FPS (with minor oscilations) also 90FPS over Kobuleti airport (previosuly I had 60 over kobuleti and 90 at the start) -ST 90FPS(with minor oscilations), almost all the time 80-90FPS Then I changed only one thing, I turned reprojection ON(use best frames). -MT horrible performance 18-25 FPS -ST-reprojection doesn't work still 80-90FPS Tried MT multiplayer, everything was almost perfect while on server first 35 minutes, then it starter twiching/stuttering(dont know how to call it) Just remeber this is not "stuttering" during FPS drop. It happens while having smooth 90FPS.( I looked at FPS counter and 90deg to the left of my direction of flying, it was smooth frames) I noticed Vram was maxed out at the time of "stuttering". I the menus effect is really heavily pronounced. Image jumps every time you make small head movements. I dont know what to think any more. I will just play ST for now and hope it will fix itself with updates. I have to try few other things you guys suggested in the next few days. Also thanks Falconeer, I am looking into those posts.

Qcumber: Thanks for the advice, I tried it and it did not help. I might try it later again but I will set it in Adrenalin software instead of inside DCS. Tomcat388th. I generally double check everything that has to do with messing with the FPS/Frametime like anti lag,vsync,enhanced sync, radeon chill,radeon boost, wait for Vert.refresh... I keep thoose things off.I went from default adrenalin setting to turning them off one by one. I tried your(radeon enhanced Sync ) advice and it did not solve the issue. But thanks anyway, advices give me hope that it will work in the future-I would really like to get MT performance gains together with performance gains from more powerful GPU. Falconeer: I am currently downloading windows update. I have latest stable AMD drivers. I will try your trick in removing device from device manager. My expectations are in right place, I belive. I know that 6950XT is only 2x faster from 1080ti and it is only an improvement in performance and visuals which I eyball to be about 20% improvement for DCS. It is actually very subjective estimation. I know for example that I could run DCS smooth if I keep same visual settings as I had with 1080ti but I will have same performance as 1080ti if I increase image quality. Sr. In DCS MT (AMD for me) it feels like something is messing with VR performance in more than one way. Something is choking the frametime and interferes with VR display.(sometimes I see it a lot more in the right eye) KoN Sorry, I did not start 2D tests yet beacuse I belive it has to do only with (VR)+(DCS MT)+(AMD) for now. because-no problems with 1080ti, no problems with AMD 6950XT in DCS ST, no problems with AMD 6950XT in other VR games. **************************************************************************************************************************************************************************** UPDATE FOR EVERYONE FOLLOWING: I think there are 2 problems here. 1.Low(er) performance on MT. I am 100% sure it happens because I tested ST and MT -same settings same scenario. P51 free flight over Poti. In both versions I have 90 FPS all the time with some fluctuation on MT but when I get to Kobuleti airport FPS drop to 60FPS only in MT! Reprojection is off, DCS settings are the lowest possibile. The first problem, low performance on MT did not happen with 1080ti, MT was awesome on 1080ti.(6950xt performs worse that 1080ti in MT) 2. Second problem is what you see in the my video.(Rememer that it also happens with all settings low, pixel density 0.5-(gpu load 71%,Vram load about 33%.cpu load less than 50%(not precise) This problem never happened on 1080ti from since I ever played VR. Not in any game, not in DCS ST , not in DCS MT. Just reminder 6950XT works well in DCS ST. No issues, no unreasonable drop in performance.(only when I crank the settings up which is normal behaviour). Thanks again everyone!

Rapierarch I tried your advice and it did not work. KoN ad Sr. I reinstalled drivers again few times using DDU safe mode with network cable unplugged. I cleared enviroment data al least 5 times. It did not work. KoN I am running VR. I do not play 2D. I tried SAM off again, no luck. Am I openXR-Not sure what that really means.(how do I find out does it run openXR ot something else. I think openXR is probably default when you start G2 but if steam vr start launching the game in steamVR then it is not openXR it is steamVR i guess. DCS ST runs on steam VR and DCS MT runs without it. On Nvidia everything is fine. On AMD DCS MT doesnt work well, but other VR games work fine. Sr. I tried many AMD settings, one by one, on and off. nothing works. openxr toolkit is disabled it doesnt work well with DCS. Thank you for suggestions I hope there will be more. Currenty I can't play MT version of DCS, only ST.

Effect that makes it unplayable is both eyes image lagging-shifting while rotating or moving head. This sometimes happens without FPS drop on the FSP counter. Next day I tested it and it looks like there is a large frame drop when simply moving head even in the start screen/menus. Image lags in stutter-like manner.(not sure how to describe it correctly) This is probably not classical stuttering,I think, image does not pause, instead image doubles and goes off center very fast. Well, shifted image might lag, I don't know for sure. my system: Mobo: MSI B450 tomahawk max CPU : Ryzen 3600 RAM : 32GB ram SSD : 1TB samsung(for DCS) GPU : Asrock RX6950xt (previous GPU GTX 1080ti) PSU : 850W gold plus VR : HP Reverb G2 things I already tried with no success. -dcs cleanup -dcs repair -removed fxo and metashaders -Low DCS settigs and lowest pixel density -reprojection on, locks frames but very low FPS(in ST repojection seems to not work at all) -reprojection off-effect extremly pronounced but higher FPS 60-90 in DCS initial screen. -Set headset frequency to 60Hz -various Open XR tool settings(prefer framerate over latency on/off, latest preview openXR on/off) -tried xr companion app-doesnt work(or crash MT),(in ST it doesnt show menu-it doesnt work) -various "solutions" on DCS forum regarding stuttering in VR. -AMD SAM on and off(resisable BAR/SmartAccesMemory) -various AMD Adrenalin software settings, from default to all off or lowest. things to notice: -I had no issues like this on Nvidia GTX1080ti, I had really good gains in performance in MT. (only xr companion app would not work or it would crash DCS MT so I disabled it.) -Reprojeciton worked on Nvidia ST and MT -This does not happen in other games I tried(MFS2020, Spaceengine) -I Instaled new gpu using DDU(meaning previous drivers are thoroughly removed) -I instaled new chipset drivers I did not update bios jet. Video was very hard to record, it was recorded at 60FPS(smartphone camera). dcs MT VR AMD problem.mp4

My problem dissapeared after I disabled "OpenXR Toolkit Companion app". I did not know I had that app, I probably instaled it long time ago. I was going to try page file solution but it was already set to 50GB, my ram is 32GB. MT seems to work fine, (off topic)--->1.my warthog throttle went crazy( all buttons turn on and off randomy) 90% sure unrelated to DCS but it never happened before. 2. and somethig is weird with external shadows in the distance. Seem like large portion of the map is in the shadow and it moves away as you approach it and it extends across the map in the F2 view zoomed out, it was following a line about east to west. It is weird I don't know how to describe it correctly. Tried different shadow settings, it is always there, on shadows low and ground shadows off seems like 90% of the time you are in the shadow regardles of cloud position. I need to investigate this more. Other than that it is good for now.

I have immediate crash also. Mt version, VR. crash report sent via game menu. Non Vr version starts fine.

I have issue with mi24 trim. It doesn't behave same as mi-8 trim. Mi-8 has perfect trim. Mi-24 doesn't trim to "click" position but it adds a little bit more, and sometimes it does that and sometimes not, not sure any more, at lower speeds it seems ok, but at higher speeds it adds more, maybe. Anyway it is not same as mi-8 trim. It might be how much does the program allow controls to be off center when returning to center , who knows. I am not happy with mi-24 trim.

I experimented a bit and found out that: -If you use KMGU bombs frames drop significantly even on flat terrain with no objects on it, PLUS frames keep very low even after long period of time after when there are no visible animations or effects of bombs. - FPS drops only when looking on bombarded area -FPS drops even with other weapons IF you use them a lot on the same location, for example-enable unlimited weapons and keep firing unguided rockets at the same area on the ground -It seems that water in not affected by this -After installing MOD 3DmigotoDCS_VR_12.0 and changing setting in sim FPS return to normal (regarding time after explosion animation is done and further) -BUT even with this mod applied I get FPS drop if I continue to hit same place on the ground. For example, I drop 8xKMGU with su-25t, everything is fine, then I repeat this 5-10 times over same area, then FPS drop sticks to bomb drop location again.

Compose.fx failed to compile. What am I doing wrong. I Can't start dcs after installing mod? 1-I made backup of my shaders 2- copy pasted (DCS World VR shaders mod by Keijo "Kegetys" Ruotsalainen)shaders to my dcs shaders 3-I copy pasted mod of Keijo "Kegetys" Ruotsalainen shader mod (from 3DmigotoDCS_VR_12.0 .zip) 4-I copy pasted 3DmigotoDCS_VR_12.0 bin folder to DCS bin folder Step 3 and 4 doesn't mater because error shows after step 2. I tried to apply step 3 and 4 after error but I get the same error after applying. Help!

Yes, this needs to be fixed. It should behave like Mi-8 but it does not.

Yes, I expected it to be like mi-8 but it is not, something is wrong with it.

There is definitely something wrong with the trim.

Regarding mi-24 trim fix, it is a lot better but sometimes it overcompesates for unknown reason. Closer to how mi-8 trim behaves but bit worse, maybe somehow AP channels interfere with trim. When you hold attitude,roll and yaw and pressing and releasing trim it should stay at that current pitch,roll,yaw(just like mi-8 does) but sometimes it does not. Also I think it could be the timing of the entire process, with mi-8 i have enough time to return stick to the center, maybe mi-24 doesn't allow that to happen , who knows.

DCS 2.7.1.7139 stable release (I haven't played beta version for comparison -sorry) Thanks, I tried this and it works! But I never had this translation problem last for long, it would happen sometimes randomly I did not know that it was WMR calibration, translation would get online by itself after few minutes. so this is SOLVED now!

I can't move my head in game (VR mode). I can only rotate. I am using Reverb G2 and I tried it with Mi-8 and SU-33, restarted pc, tried SP and MP same results. There is no translation of your head in VR only rotation. My hardware is fine, it works with MFS2020. If you need proof I will try to record it with my phone, if you want. EDIT1: DCS 2.7.1.7139 stable release

Using DCS updater speed is 300 KB/s , I will never download this, I tried cancel to switch to HTTP and uninstall and download again but it is the same.

Nevermind, it works now, I installed 2.2 version and copied FreeTrackClient.dll to bin folder. Do I still need headtracker.dll now that it works, I probably have it there already becouse I was runing freetrack noIR with it...thanks anyway

I tried everything but Freetrack doesn't work in DCS 1.5. Freetrack noIR works but it doesn't support one ponit tracking. Can anyone summarize for me what do I exactly need to do to make Freetrack work in DCS?? (Assuming I have clean install of DCS 1.5 for example and properly working tracking device.) Please help!

Hello! I noticed both Su25 and Su25T don't show rudder trim deflection on controls indicator (Ralt+Enter) and don't show visual deflection when actually looking at rudder from outside and trimming , nothing is moving,but it does have aerodynamic effect,and when taxiing aircraft moves to one side. Which proves that aircraft is trimmed. Aircraft control indicator shows when pitch and roll inputs are trimmed but for some reason yaw doesn't show, it stays centered. Only indicator of rudder deflection is green light in cockpit, the green light is on when centered. Is this bug or something else? Does anyone knows something about this? F15 and Su27 work fine regarding rudder deflection when trimming, visually and it shows on control indicator.
