i found 2 tips for Apache, Quest 2, I5 12600k, 40gb, 1tb ssd, 3060Ti, i have the same problem with fps, dropped to 45 with maximum performance to 7,8, 11 fps with Apache, my 2 tips it's low the Preload Radius to minimum and start the Apache ON, i don't now why if low my MSAA 4 to Off my fps low too, same with anisotrophic filter wit 16x to 2x the same problem and i use OTT (oculus Tray Tools for best performance) but when flow F-16 F-14 the fps up to 45 and stay 45 fps like a stamp in any map

Im not a stake holder yet, but my brother has it and noticed for FPS that outside views are fine in VR, but inside the cockpit are trash, like single digits.  Something about that Apache cockpit is trashing FPS.

It is definitely a problem with this particular rig. I ran the Apache on my AMD Ryzen 9 5900X 3.7GHz, 64 GB RAM, AMD Radeon RX 6900 XT system with a Pimax 8KX and was getting steady frames in the 50s and 60s. What the hell could be causing the problem on my i9/3080ti rig!?!

Dont feel bad, the apache crashes DCS when I load into vr. I cant even play in VR in this module.

Quest 2 native resolution is 1832×1920 (per eye). If you are running what equates to 3950x2070 per eye than that is prob the issue lol.

I dont have a Quest so not sure thats possible but putting it out there just in case.

 

That's the phsical resolution, LOL, If you are not using the slider all the way to right than you are downsampling the FOV center. That's not an arbitrary resolution it is the resolution where you get 1-1 pixel projection for the center.

Just bringing it up since I had my G2 set to what I thought was 100% and the reolution was set to some insane level in SreamVR. The 2070 threw me off. I dont have a Quest 2 so I thought maybe something similar was happening to you in whatever Occulus uses. Just trying to help.

Does anybody have any idea why the problem would only be with the Apache and no other modules?  It is not like a slight or understandable hit to performance...it totally kills it, bringing the frame rate down into the teens. It doesn't make any sense.

The FPS is fine at my end. However, I do have issues in more dense areas, like the larger cities on the Syrian map. The game looks some sort of shaky and it has some sort of lag/delay. I am also getting a white transparent bar at the bottom of the screens inside my Oculus Quest 2. 

Normally when I fly the F-16 this actually never happens, but with the AH64 it does in the dense areas. I haven't tried to set the graphic settings lower - but I'll do that tomorrow.

My specs:

Oculus Quest 2 

If anyone has other suggestions, I look really forward to hearing your input on that!

Not much of a problem for me. Had some stuttering instant action mission Syria map but once away from airport (fire and smoke at airport and other air traffic at airport) not much of a problem.

Nope, but i have no problems if the fps drop to the 30's in VR, i was running an Rift S with an 1080ti for a long time. But i had to increase my page file(2xRAM size on M.2) a couple months ago to be able to keep playing MPwithout DCS crashing.

The only thing that is killing my performance(2D/VR) is this bug:

 

I have similar settings and not much of a problem

I get 60 fps in any other module (F16, F18, AV8B, A-10C2, Huey, Ka-50, Yak-52, C-101, Mirage ... ) and 30 fps, including shakiness/lag with the Apache with the same settings... Not willing to sacrifice the quality I have and all the work it took to get there for the Apache . I'll wait for the next update to see if it improves...

If you swap monocles rendering from right eye to left or both eye, FPS improves vastly plus it doesnt crash on me.

It would be helpful if you guys shared your settings, those that are not having an issue, and those that are. 

Also make sure you are not running any mods, do a slow repair, and make sure all your drivers are up to date. 

It is possible that the -64 will still be optimized through EA, but with some having no issues and some having them, please look deep into your settings and back ground apps. 

Thanks.

For some of us thats a tall order. Since I reinstalled DCS on a fresh format of Windows 11, spent the last 2 days tweaking this and that just to get acceptable fps in vr. I even just found out that Process Lasso in Windows 11 is more of a detriment than beneficial and its just best to use task manager to kill unwanted programs. So to clarify, you want settings inside DCS exclusively? Or for those of us who run mixed reality portal and steamVR to include those settings as well? That last part is easier said than done.

I and I am sure others that are having issues will take any info you can share with them. 

Whatever you can do to help your fellow simmers, or help us diagnose is all we can ask for.

There are a lot of settings, which ones are most relevant? I wouldn’t think settings would be needed here and that hardware would be potentially more dispositive. The problem is ONLY with the AH-64D. All other aircraft on the same map and in the same set of circumstances perform as expected. Only the frames on the Apache tank.

PD is 1.1. I’ve reduced it to 1.0 and that did not help.

steamvr global res is 100% as is per app setting.

textures and terrain on high 

shadows flat

clouds and water standard

msaa off or x2, no real difference

AA off

I only run with aircraft mods, which I’ve tried removing and openVR fsr, which I have also tried removing. No change. 

Anything else?

2 things I say I had to do to even get it to play regardless of FPS is that I absolutely needed to turn MSAA off and monocle rendered in anything but the right eye. Otherwise I cant even get in cockpit without a crash or a slideshow. Honestly I felt lucky I could even get that, because I keep trying again and again to repeat that winning combination and I cant. I cant play in VR regardless of what settings I use.

 

Im about fed up with vr anyways.

 

edit: feels like I might be going somewhere. I deleted my presets from the saved games folder plus all options and config and started fresh. Started the startup tutorial with everything at original settings unmolested and at low res everything and it looked like I had everything maxed out. Straight up 45fps, and the only thing I changed was left monocle.

I don't have any shader mods or anything like that... But I'll retest without any mod after a slow repair to see if changes... My original post updated with SS of my settings

Thank you OP for making this post.  I'm in the same boat. VR is completely unplayable for me, and a friend of mine who I was gonna fly with. 

On a i7 8700k with a 3080. Could fly the Huey and the Hornet no problem in VR. Absolute slideshow in Apache. I really hope the devs can address this issue for us VR users.

Hey Guys,

 

I am having issues in my Reverb G2. I am on a fresh install of Win10 updated all win10 updates as of 3-18-2022. I just DDU wiped my older drivers I was using and installed fresh 511.79 nVidia drivers which was worse then the older drivers I was using but just wanted to rule that out. my specs are in my sig but a pretty decent system save my GPU which is only a 1070GTX.

 

I am on the lowest settings in DCS and mopved my Preload Radius to 75K which helped a little. I took some shots of my settings if anything is missing Please let me know what you need. I was playing the Instant action mission Hot Pit takeoff in Syria.

 

here is my fpsVR log saves:

this report took about 60minutes to gather including swapping nVidia drivers and getting screensnips.. hopefully will motivate others to do the same. and If you need any other info Please let me know what you would like to see besides my bank account numbers.. 🙂

Deleted everything but my input folder in saved games/config and started fresh. The instant I turn MSAA on it crashes. From the looks of it, it is definitely causing an OOM on the GPU as my graph had it pegged at 11.9gb out of 12.

 

Anything more than what I have in the screenshot immediately below causes me an OOM. This is the absolute maximum I can fly with in the Apache. Normally I have all these others maxed out and MSAA @ 2x. This aircraft is one massive resource hog. With the settings below, I still have memory topping out at 11.5gb VRAM and system ram upwards of 6gb. Thats just sitting in a cold and dark setting. Note the A-10CII has maxed settings and tops out at 45. I find that odd because with the settings below, I am well within the minimum of 45fps in the Apache...but anything more than that and it straight up crashes.  Also worth pointing out is that I have my PD at .9 and my SS in steamvr set at 80%.
