There must be. I use DCS standalone with openXR and I am not getting this popup.

could not find the NVIDIA NV_cache folder...there is a GLCache under C:\Users\****\AppData\Local\NVIDIA though. Did absolutely everything else... Still getting these frametime spikes by default Not sure what happens / why it goes away if I change a setting (like visib range) that triggers a restart. Because it really solves it everytime but only until I quit that session!

Thks @Flappie. Did both but no impact. However, I can confirm that after a restart triggered by switching visibility range that issue is fixed for the session. But only that session.

Done more trial on this... no amount of cleanup / repair/ removal of mods has done anything yet. I have found a way to make it go away... not a nice one: I go to settings -> change a setting that requires restart ( I pick visibility range and switch between extreme and high) ... After the restart the issue is gone... but only for this session of DCS. @Flappie besoin d'aide Anything that pops given your experience?

If have recently started to experience random FPS drops in VR down to 15-20 fps for 2-3sec. I am using the F15E /Instant action / navigation practise (ready on the ramp) mission in caucasus. There are numerous F15s / F16s/blachawk and co planes so lots of textures / models to render. The FPS drop happens immediately and during taxi (first 2min). I tried to debug by removing all mods, dropping all setting, updating nvidia driver, restoring nvidia driver settings etc. Followed @Flappie detailed list (see his post further down this page) So far I have found just one peculiar way to prevent these spikes: Upon starting DCS I go straight to system setting, change the visib range setting to something different... DCS restarts and my spikes are gone. There are only gone until I restart DCS again though. Logs attached. Nvidia (driver 551.23) settings are default except power management at 'prefer max perf'. I am running out of ideas here. If someone can decipher the log and point me in a direction they would have my deepest gratitude dcs.log DxDiag.txt

I have started to experience crap like this about couple weeks ago... I am all good locked at 45fps then randomly frametime shoots up a I sink to 20fps for 5-10sec... Tried everything so far... remove mods, check windows power setting, updated nvidia driver and reset its settings... nothing works and it seems to get worse rather than better.

Did you solve it? I have a similar setup and just started experiencing big fps drops while taxiing to the runway along a busy parking full of various aircraft styles... big spikes in frametime for 2-3sec. Goes away once in the air. Hence curious about what helped u. Thks

I see your point but do not think it is valid technically. With similar roll rate and acceleration a platform with more travel range will just be able to have an extended range of sensations. if you can pitch 40deg then you can feel a stronger G force on acceleration for example than if the platform can only roll 20deg. The motionsystems rolls at about 50deg/s I believe. The MotionXp can roll at 150deg/sec so anything rendered by the motionsystems should be rendered exactly the same on the MotionXP. And speed and travel are totally customisable anyway through the software. The fact it can travel more does not mean it will travel more to render the same sensation. In fact it will not. It will only if it needs to in order to render the right sensation and if the platform has only a shorter range then it will just stop before and not render as much as one with a longer travel range.

Indeed. They use Flypt Mover and Open Xr MC for the VR compensation. They are cheaper, a bit more DIY but also have bigger motion ranges than motionsystems and the various tests / videos I have seen show a very stable, smooth and quiet base.

Anyone here using this motion platform? I would love some feedback / pros and cons

Weird. Don't have that fortunately. You may want to reach out to Varjo support

Seems Razbam feels these modules are not worth maintaining and are happy letting them decay? Bit strange to me. Training and campaigns are so important elements of a module and bugged out training missions / campaign put out a very bad image of a module and it's developper to anyone buying them

Bit of a shame that training missions have not been updated... It was a brillant module with a fantastic campaign but now bugs (due to new features / dev) make it look unloved and shabby instead of better

Ok. I am surpised. I have an i9 14900 and 4090 and a definitely cpu bound so go for it!

R u GPU bound now with your new processor or still CPU bound?

Now that AUX default to FM and needs to be manualy switched to AM via the Radio UFC menu we noticed both pilot and WSO need to do this as the two seats are not synced.

Makes no sense for DCS at this point anyways

Been seeing this a lot... on my side I have motion smoothing on and 45 lock ... without motion smoothing low flying at high speed ... trees and houses are ghosting too much. I do not get spikes/drops on my system

it will be a good upgrade no matter what. The foveated rendering of the aero saves you on GPU performance and you can always adjust the resolution of the Aero down if the 3090 is struggling (either through the varjoBase software or the foveated .lua file

to help find the culprit: In DCS ... under controls select UI then General then your aircraft. Under each one press / scroll your thumbwheel and see if something is bound. Do you use any other software like Vjoy to bind joysticks? If yes then check there Last... bindings in your HMD software

yeah that is definitely not what we see

My .lua Not that the miror looks fine, only in the headset do I get that (full screen nvg with black mask where my gaze is) Options.lua

Thks. Does it passes IC for MP servers?

@BIGNEWYSeems they have broken it again with the new patch 2.9.1.48111 Can you raise again plse?

was fixed with previous update and now broken again. In VR with varjo Aero and foveated rendering I get the mask again following my gaze and the entire vision is NVG. not using any Mod
