I think people should be a bit reserved in blindly stating "the apache I'd unplayable the vr". It may be for some depending on hardware and settings but for many of us it is perfectly fine. There are so many variables in getting everything to run smoothly, from Windows, wmr, svr, other apps and background processes running. I'd always start with some good pc hygiene and check the system thoroughly outside of dcs. 

I've been getting excellent performance with g2, 6900xt and 3800xt. Running native resolution in sp and mp. Mp is noticeably lower fps and higher frame times but quite acceptable. Sp is totally smooth even with ihadds, flir, pnvs and anything else running. 

I even saw improvements in performance with the latest patch. 

I love TED talks 😉

Anyways, the consensus is that the majority of apache players are having issues outright with max textures and nothing else. Everything points at an OOM scenario; for those of you that have different results, is how much memory do you have offloading during your flight. Willing to bet you might have something that may or may not be clearing your ram cache on the fly preventing an OOM. An OOM is basically a hard crash due to the memory being congested and unable to move. For some it might simply be how their headset is hooked up to the back of your computer. For Reverbs G1 and G2, its either USB C or 3.0 on top of a DVI (i think thats what it is), and its been known that some motherboards have bandwidth issues and should resort to a powered PCI-E USB hub. So whats different here?

My fps in steamvr is unplayable until I press alt+enter to make the mirrored view full screen. No idea why or how this works but it's the only way it's playable. I'm on a 9700k, gtx 2080, 32gb ddr4 and an ssd.

These are people who have noticed an extreme difference in playability between the apache and other modules. They're not moaning because they have weak or badly tuned rigs. They went from X framerate in other aircraft to 0.1 - 0.25X framerate in the apache. It's a problem specifically with the apache, for some people.

Take my case. I've had playable frames for years with textures high. I jump in the apache and it's a slideshow. Back to the hornet, it's fine. I change textures to medium, the apache is fine. It's a total cop-out to say "tune your rigs" to people. It's a demonstrable, reproducible issue with high textures in the apache - and *only* in the apache - on some systems.

Let's say it's a GPU memory usage issue. You have a 16GB card and see no issues. Other people have a 12GB or 8GB card and see issues. Or maybe it's an issue specifically with NVidia cards. "Tune your rigs" is a pointless approach to problems like this, unless your proposed solution is everyone should upgrade to 16GB AMD cards to make up for the apache's lack of optimisation.

Personally, I have a pretty good FPS in AH-64, basically 45 Frames fixed, so the re-projection works ok. Over Aleppo (Syria) where I have a test mission they drop a bit but this is a special test. But what I noticed is that Reverb has a problem with frame hold as soon as the new FLIR will be on the gunner's screen. Then the stutter starts to take place. I think there is a problem here and the new FLIR should be optimized for VR as well.

This exactly, all other modules run great and great for me is locked ASW at 36fps, with Apache it stutters and rarely maintains that 36 ASW lock.  Same thing happened when the Hind was released, Apache is early access and needs a couple optimization passes.  I will try dropping the textures down to medium for Apache, thanks.

Same here, and I'm only running a 2080 super with a HP Reverb.  I don't run shadows (never have), and have textures set to medium instead of high to give me plenty of headroom though.

The Apache in VR runs great for me, EXCEPT for on the Syria map.  If I run it on Caucuses or Persian Gulf, for example, it runs smooth just like my other aircraft modules.  But, when I load anywhere into Syria, it stutters so bad it's unplayable.  I will try lowering my textures to medium, as suggested above, until a patch is released.  Thanks, fellas.

To be honest, id have to see them side by side to really tell a difference. Even in medium its extremely detailed and very crisp and clear. I checked the 16 and 14 as well, samething. In high it makes me wonder now lol. I got good performance with changing the texture though. I only have issues after target being destroyed on attack runs, it seems like the smoke/fire is causing something (This is MP on hoggit training). SP kind of a different story and not enough test data to give an answer.

63 dollars spent I can't even fly the Apache, I get 11 FPS.   Play the Charnwood campaign and constant 45, on a 3080 with reverb g2.   Not happy

I lowered textures to medium but made little difference, lowered PD from 1.7 to 1.5, again little difference.   I maxed 13 frames but mostly stutter, close it and start charnwood and I get 45.  I don't know what the problem is either,

I'm willing to bank its some settings that need adjusting. For you to have a g2 and a 3080, i am willing to bet that you will have successful FPS to fly around in, buttery smooth too. It doesnt make sense I get that because in another aircraft you can achieve higher frames, but there is just probably some weird setting or workaround you might have to do. Just couldnt tell you what exactly that is. There are folks in this thread with "lesser" card than yours and are getting it, so you have to be able to.

Yep I agree, I'm a VR newb, I setup DCS months ago to run great in VR.   I just changed all the settings in DCS to very low distance, low textures, pixel density to 1.1 made no difference in my frames....  Might be some setting in steam vr.  Regardless of what I changed in DCS it made little to no impact on my fps in the apache.

A lot of us gamers have LED lighting inside our case. The biggest FPS killing in DCS is stuff like Asus Aura, Corsair Icue, stuff like that...try going through your taskmanager and kill stuff that ordinarily would be on for decoration. Believe it or not, but I get an additional 15fps just turning that stuff off before I even get into DCS and its a game changer for the most part. With it on I get wicked stuttering. I have this massively overclocked system; I still tweak windows for a few days getting things straight before diving into DCS. 45fps in VR doesnt mean you get more than 100fps outside of vr, and half the time its bloaty crappy stuff like LEDs that tank performance. Give it a shot. I know some ppl that fly the Apache using a G1 and a 1080ti, and some of us use Kegetys vr shader mod to help mitigate fps loss.

Ha setting textures to medium helped definitely enjoyable now, thanks for the tip.

I found my issue it was in the steam VR settings.   Had per eye resolution set to 50% around 2160x2160, but under DCS I had a multiplier set to 60%, dropped this to 40% and then had to lower the textures from high to medium like everyone else.  Now get 41-45 FPS.  I also noticed pixel destiny now plays where before when I changed it, had no effect, so whatever I changed in steam vr fixed me.  Right now I've got pixel density set to 1.7 .

Virtually the same rig as yours apart from the GPU is a 3080ti, also in the G2. Getting the same result as you too. Syria is currently a no go area for me. All other maps run fine. Going to try to reduce textures when I get home and see if I can actually fly in Syria.

Can't see it's relevent but the more info the better. what model of 3080 do you have mine's an MSI Gaming X Trio.

I read someone had preload radius set at max, reducing that solved their issue. I have it set on the minimum, PD is 1 and it is great on any map other than Syria. Worth double checking that setting.

 

Edit: Just seen your response above. Glad you figured it out. I'll leave the reply here though, it may be useful to someone.

Thanks for the texture advice! I struggle with my F14 and now the AH64 in SOME places. If I run the Apache in my Tonopah test area everything is fine. If I enter the cockpit in Kobuleti my RAM go´s crazy and I have to alt tab every minute or restart DCS. F14 the same. Ready to taxi on the Supercarrier impossible, when I start looking around. F18 on the same deck no prob.

All that started when using my Reverb wth PD 1.0 and Steam VR SS 3100x3100, MSAA 2x, which delivers the best picture on my Reverb. 2080ti VRAM is maxed out.

Now turning textures from high to medium F14 and AH64 work great EVERYWHERE and even with NVS  on my HMS.

And it´s hard to find any difference from high to medium in the pit. I was searching around and found only one part in every single cockpit:

Turn your AH64 pilot head back right, there is a small plaque mounted at the seat. The letters are readable in high only, medium they go swimming.

Turn F14 pilots head back left, you can read the ejection seat checklist only with high textures.

In the F18 there is an external electrical power plaque on the left sidewall. With medium textures unreadable.

So if there are only these few parts bad on medium with an 3100x3100 Reverb picture, it makes no sense to run my Reverb with high textures. Or do I miss something? Externals textures I see no difference, too. Maybe high texture was made for 4k or 8k flat screens only?

Reduced my textures to medium and now really smooth in Syria. Haven't noticed any huge difference in picture quality either. Monacle is on right eye only too. Thanks for the tips everyone

can you post your system spec and which headset? 
high PD values combined with high headset values can create huge bottlenecks.

I use a reverb G2 PD 1.0 steamVR 60% and get 45 - 90 FPS depending on altitude

I think I finally nailed the config:

1) DCS: textures to medium 😞

2) Oculus, refresh rate to 80Mhz

3) Oculus bump resolution to 4864x 2448 

The rest of my DCS config was not changed. This gives me sharp cockpits with locked 40fps for the Apache and the other modules (I see lots of spikes of 80fps in the other modules)

Perhaps, the folks that are reporting that they are good, should mention their refresh rates for the devices. It was the critical element for me.

Thanks, are you using the OC tray tool?

1.7?? I have mine set at .9 and I have steamvr set at 80%. Yeah I can see why you have poor performance now...but if it works for you now, then great!

What about the FLIR for you? For me here is a problem (new kind of FLIR on the screen), if it works as day or night = stutter.

Medium/Hight textures = no any changes for me. But FLIR on/off has a big impact.
