Hello Nvidia 3090 all drivers. Default shadows. Assume all are maxed out. This issue is causing immense flickering and shadow draw issues. It may or may not be related to my other issues. I can also observe this very sharp transition from good shadows to bad shadows in X plane but the range is about 2-3 times that of DCS from the cockpit. The high res shadows are being rendered only marginally in front of the aircraft and main focus seems to be behind It seems to depend very much on angles. From behind or in the cockpit its quite bad but if you turn the camera from the opposite side then everything seems just fine. Its as if things are somehow reverse. I see the same on my Nvidia Laptop. I dont know if this could also be related in some way to my other AA issues Long version. You can see it on trees, the walls and pretty much everything.

Here's the same issue in 2d

Im going to add this a couple of places as im assuming very few actually bother to read this. This is quite impossible to miss really. The shadows and im guessing other details as well given all the AA issues and such i have seem to render at really low res outside of 10-20 meters causing extreme flickering. 3900 SS 4x AA 16x AF All shadows high and default. Short Long version

Fantastic work! Ill be building one asap to replace my MSffb2

Ive been thinking about doing my own FFB using motor controllers or possibly some servo motors but wasnt sure if i could do the directX ffb stuff. Would you mind if i had a look at your Ard file?

Probably not right away but i hope they will add support for it. In the meantime ED could have things ready

A video really cant do it justice but here you go. Its just a really really bad experience in VR at even 4x AA and 2700 SS and Ultra clouds. Its not all the cloud layers but these are just awful. Combined with a jittery Pimax will have these flicker like crazy all the time.

Presently on my 5900X and 3090 i am quite GPU limited in the resolution and graphic options for VR (Pimax 8kX) and even if you are CPU limited being able to crank up the graphics options and have double the res and not to mention AA for the same performance is something ED should implement as soon as humanly possible. This is actually huuuuuuuge for VR.

Hello Windows 10 multiple versions. First computer. i7700k 1080 TI all drivers Second computer. Completely new system. msi tomahawk x570, 5900X, 3090 All drivers. Worked fine for 5-6 months. Then boom. Tested in 2d and multiple VR HMD Ive decided to make a new post here in the hope that some light can be shed on this issue. This however is nothing the end user can fix nor DCS but there needs to be pressure to have this issue fixed. I no longer think this is an issues with anti aliasing but rather something underlying. This is also reinforced by the fact that i can do 6000 super sampling (and that is fixed so steamVR does not reduce it or limit) and it wont really make a difference. You do however notice a difference when setting it very low. So is it somehow limiting the texture/line size so you cant fix it? I do also think this is more common that people realize but may not notice so much in 2d. I remember especially thinking when a guy said to me for spotting in VR, Jaggies, alive, no jaggies dead. Taking HMD and SS into account of course i thought. Ok well i dont really see any jaggies so i cant use that. Boy is it different now. And no its not something i just suddenly noticed and cant un notice. The difference and boiling picture is rather extreme in the HMD: I have made a post in VR issues before back in 2018 and some updates on that but it warrants a new post. This is something that has happened overnight (the difference is huge) and the only commonality between the cards is that both has been used for bit mining. I do however not see that in other cases around the internet. I've compiled some videos but i can give more examples if needed. From another person. There are multiple around if you search for broken AA but this is the best illustration of the same issue. Its like something just stopped working on the transitions and give jagged reflective lines which any amount of SS or AA just wont do anything about. Doing a tilt test here. When tilted its what everything used to look like pre issues. If i tilt the camera about 45 degree you have a little bit of shimmer. Level and its a shimmer mess. It just feels like the picture is boiling inside the HMD. 4x AA 3900 super sampling. Tons of issues which again tilting the HMD does help. Here's a 2d video with 4x AA and while YT compression does reduce it a tiny bit you can see there is lots of shimmer especially in the shoreline and ridges in the distance. Video of the screen 0x AA Absolutely atrocious. Video 4x AA. Its better but not by much Works on some but marginal difference on the white line marked by pointer. Growing and shrinking white line top right. Mouse pointer flicker. AC 8x AA 3500 SS. Hud and lines flicker like crazy. Same with the white writings/spray textures on track on the Nordschleife. Same deal as runway textures etc in DCS.

Might be you have an issue with AA two (which quite a few has without knowing) There's a fair few reports of AA stopping working or not working properly and its extremely visible in VR. Happened on my 1080TI and then i had a new system which was fine for 6 months before it suddenly was a night and day change. Ive heard other guys say, new system fine for about 6 months and then whack. Every ridge edge etc is a boiling/shimmering mess and it has not been an issue at all. Runways are obnoxious and i could fly just fine with 0x AA and 3500 super sampling before. AA does mask it but does not seem to work on a lot of these lines. Disregarding that for a moment. Then is also something to do with sharp line and texture edges and such which is especially visible in VR and developers have to think about it when they create things. This is the ones we seem to be most plagued with. https://forum.unity.com/threads/white-jagged-edges-based-on-angle.491775/ "This one is caused by the thinly rounded edges and Fresnel reflectance. It's shader aliasing, which MSAA doesn't handle. As an edge becomes parallel with the view direction it becomes more and more reflective. At parallel it becomes a perfect mirror. In the real world this can never really happen since something parallel to your view can't be seen. In computer graphics this happens all of the time since the surface normal is coming from normal maps and interpolated vertex normals and not necessarily the geometry facing." Here's on the AA issue that has to do with AA only working right in exclusive fullscreen https://answers.microsoft.com/en-us/windows/forum/games_windows_10/update-in-windows-10-broke-msaa-anti-aliasing/e74d45e3-8b43-40c2-92b8-be7965b979b6 Vid from that thread.

View ranges in general are horrible but these tree's growing even when you are directly on top of them is quite annoying.

If you want the best then you got the Varjo XR3 with human vision in the center amazing lenses and around 100 degree FOV with no foam on. https://varjo.com/products/xr-3/ There's some reviews of the VR 3 cheaper version here. https://www.youtube.com/channel/UChLDzAfTbE7hv0ipGTkHV2Q For very wide FOV the Xtal https://www.xtal.pro/product/xtal-8k-virtual-headset Then you got the Pimax 8k X 4k and massive FOV for normal consumers which i have myself but this is not plug and play. A lot of people get eyestrain and its PITA to fix and sometimes impossible as you have to tune in multiple dimension for each eye. Or you could be totally fine out of the box. You just dont know https://pimax.com/product/vision-8k-x/

Ive been going trough the net again looking at this issue but of course no fix. It really does seem like a systemwide windows issue. I came across this one which illustrates my issue very well but since things also looks so much worse with 0x AA there has to be something with the rendering too that is not working as it should. My picture is pretty much boiling in VR with the constant movement ant its just a horrible experience. The odd thing is that the old FS2004 in exclusive fullscreen has the AA working in the video below. Sadly my fs2004 Cd's are broken so i cant test it And the post. He has reported it around various forums. https://www.prepar3d.com/forum/viewtopic.php?f=6312&t=141370&p=242753#p242753 And a playlist i made with various footage from DCS and other games

I have changed my initial impression here but you really need to change the foam and get it super close to get an acceptable vertical fov (The narrow vertical fov is still something we dont want) and sweet spot. Its quite narrow and you have to micro adjust at default foam distance. The picture is really nice, the motion smoothing excellent and the FOV quite good. Sadly the performance at the moment seems to be quite bad. It can barely keep 90 FPS in the menu with only 3000 SS on my 3090 with no AA and struggle to keep 45 I could run 3700 and larger fov on my 8kX and get better performance. Even with Kegetys mod it dont really gain much so i think there is some other issue here on the latest Nvidia drivers... Its a shame as running 120hz is simply fantastic and even at 30 fps if you can take a bit of stutter and artifacts its smooth. Not gonna run like that but i think i could keep 60 once the performance issues are sorted. There's also plenty of tracking bugs in other games and vertical alignment issues in DCS. This software is not release ready. All in all though I'd take this over the G2 any day and since i get a lot of eyestrain with the 8kX im almost and very close actually to give it up for this one. Sound is pretty shit.

Updated impressions I have changed my initial impression here but you really need to change the foam and get it super close to get an acceptable vertical fov (But VR should never accept or adopt this aspect ratio) and sweet spot. Its quite narrow and you have to micro adjust at default foam distance. The picture is really nice, the motion smoothing excellent and the FOV quite good. I'd take this over the G2 any day and since i get a lot of eyestrain with the 8kX im almost just almost willing to give it up for this one. Its a close battle as the center clarity is much better on the Vive too. Thats what you are giving up on the Pimax for the FOV with the center lens spot being about 6-7mm outside your natural ipd It does have a lot of shortcomings in audio/mic which i cannot understand why they didnt upgrade but for picture only id be very happy with it.

Its been a while since i had the G2 so i couldnt give a very accurate comment on that but it feels about the same, perhaps a bit wider on the VP2. Hard to say.

Clouds are absolutely terrible for me. on standard Just boiling flicker/shimmer on the edges Same thing in the 8kX and Vive pro 2 . High is slightly better but only ultra works. Still shimmers a lot at distance

First impressions are so so. Install and setup is PITA. Lots of issues. Colors are good and FOV fine but the vertical FOV is lacking. 8kX for immersion. G2 for clarity but not by much over the VP2. VP2 for a bit more fov. I cant really recommend the 8kX due to the eyestrain issue i and so many others get but you really cant beat it if you dont. Its a beast for immersion. Today get pretty severe cross eye up and down as the images does not line up vertically in DCS world. Fine everywhere else and when i open OVR Toolkit in DCS world its fine and as soon as i look at DCS its double vision and eyestrain. Dont know what is going on but DCS is currently unplayable for me.

0x AA is absolutely atrocious now and this is in 2d. I could fly just fine with 0x and 3000 super sampling in VR but imagine how it feels now. Some kind of issue in the render pipeline for the HW. 4x AA . Better but not by much

Well it has happened again. Over night its gotten 10 times worse and AA seems to be completely broken. This time its on a 3090 so its pretty safe to assume it is a hardware issue. The luck... I dont know what drives the AA functions in these cards and even the 0x AA looks much worse than it did with 0x AA before. AA does have some minor effect on some lines but there's something underlying that is completely broken.

Settings really does not matter. Anything over 70-72% GPU use will cause the issue. So i always have to aim to keep below 70% if i want a smooth experience. I see Don wan here has the exact same thing. @speed-of-heat Sure frame times matter but im sure you got my meaning. I cant see anything on there that would make this effect.

Aight. I may remember wrong on the G2 as its a while ago and i didnt have it that long but as far as Pimax goes frametimes dont matter. As soon as it goes over 70% with no frame time spikes or anything close to being over the limit (sitting at 60-65fps without motion smooth on, 45 on) on the cpu side it will start to lag but oddly mainly when looking sideways. Im on 3600hz 32gb and the cpu frametimes can be at 7ms. They have no effect. Seeing as its across two systems and only in DCS im tempted to think its a DCS issue.

On what HMD? I had it on my i770k 1080TI With Pimax. 3090 5900X with Reverb g2 and Pimax.

Hello chaps Ive noticed that whenever you go passed 70% GPU usage in DCS you will get frames lagging and rubberbanding when you look off to the sides or rotating the plane. Its not really stutter but i suppose you can call it that too. I really wonder why this is and how it can be fixed since it leaves a large amount of perfomance out. This was also the case on different computers. I have this is my Pimax but i believe i saw it on my reverb G2 when i had this too. I suppose its a limitation of the DCS engine but are the developers aware of it and working on a fix?

CTS 2.550 TARGET_v3.0.20.427 and TARGET_v3.0.20.826 no trackir Pimax 8kX Tm WH stick Tm cougar throttle. After doing a rebuild i will get Compile Error: Symbol not found: TrackIR in DCS_World.tmc at line 167 no matter what settings i use. If i comment out that in the .tmc file it will just give another symbol fault. No hardware changes Ive reinstalled target and cts (and full cleanrup) a number of times. Any ideas?
