Tips to get nice looking trees together with 3D effects. Leave the forest visibility setting at 100% but reduce the detail as needed instead. This will eliminate texture pop-ups on trees when you fly by for really nice visual treats. Trees and forests look especially good in Marinaras map. Yep. This and MSFS are the only OpenXR games I have, everything else I tested was via SteamVR OpenVR.

I also find that I have less cross-eye issue with this profile. Aiming is easier without having to close one eye.

My profile 3DVR.zip which should be the same as the one in video, for people who don't want to do it themselves. Load with nvidiaProfileInspector app and apply changes. No idea, Don. I see the diff right away, it's neither subtle nor exaggerated in terms of pop-out and depth effects, just about right for me.

I don’t use a custom NVIDIA profile with DCS if that’s what you meant.

If you have a profile that loads with DCS then add parameters to that profile. The software is just an advanced editor for NVIDIA GPU profile files, it doesn’t really mess with anything else.

Yes but you have to reload and apply changes after each reboot, as the OP stated.

You can do either, just gotta understand how it works. As the OP stated in his original post, do it his way with a custom profile and it won’t stick after reboot. It will be permanent if you add those extra parameters to the global profile.

Flat/Default. The 2nd value doesn’t matter much because it can’t go higher than the general shadows setting.

I’ve been scratching my head with this mission also, actually most of Apache missions gave me troubles one way or another. Does the trigger zone stuff work correctly in this mission?

No it’s system wide, activated with anything VR that uses directX. I just tried on a bunch of different games around 8-9 even VR movies and they all work. HL Alyx in particular has great depth effects. I have to take a break now though, getting a little nauseous from doing this with action games.

Did some flying in the other flightsim and I have no words to describe. It's like magic, when you combine photogrammetry, OpenXR, Foveated, 3D stereo profile together in VR. Innsbruck airport and the surroundings look so so good. My fps seems a bit lower than what I can remember though, so more testing to do. There's already a built in profile, VRdirectx and apply changes. There are more VR profiles also but that's the one to use.

Yep, you're right. I'm probably going to mess around with the individual parameters later. Just did a mission in the GA campaign conversion with the Apache and it was wonderful. This seems system wide also, which means it should work with other directX games like MSFS, etc.

Since I got the Aero, I pretty much have no reason to play DCS in flatscreen since the image quality is pretty much the same as my 4KTV. Now with this 3D stereo enabled, it completely brings the visual experience up to another level, that is not possible on a flatscreen. It's like watching a 3D movie at the theatre. The world feels much more alive, and individual trees actually look 3D rather than a mere flat object. Back to flying now, lol.

For me, I can't play VR with the old setting now that I've experienced this. This is VR + true stereo 3D.

OK I just tried this with the Aero and Apache, and I have to say that I'm quite impressed. Cockpit elements are popping out more in 3D stereo (MFD panels, switches, top compartment above UFD, etc.), when you fly around trees and buildings look more 3D rather than flat. And there is no performance drop since you're just changing the 3D convergence factor. I would rate this up there with Reshade, OpenXR, etc. in terms of improving visual quality. The F-14B cockpit looks absolutely insane in 3D stereo, everything pops. You have to wonder why this isn't a default NVIDIA setting for VR.

I’m still having trouble with this, can never get it to align properly and that’s why I prefer hot start for now. This is going to be tough to make it work right in VR since we don’t have exact same IPD, headset, eye offset, etc. I don’t even use the default cockpit position as I find it a bit too low and too close.

No idea about effect of MR on CPU frametime as I don’t have a WMR device, but V sync on the Aero and motion smoothing on SteamVR devices tend to affect GPU more than CPU.

OK I did testing on that Caucasus hot start instant mission and it surprised me because it was actually more taxing than Syria. My CPU frametime was 24-25 and GPU 22 ms, so the CPU is the bottleneck in this case. Now when I turned to the side to look left and right--away from the aircraft shadows, the CPU frametime would drop down into 19 ms range. The culprit turned out to the the shadows on the runway (pretty complex on the Apache with all those moving blades). I turned off shadows and CPU frametime dropped down to 17 ms, while GPU frametime instead became a bottleneck at 19 ms. The frametimes got even better once you're up in the air. Now imagine placing 10 of those Apache on the same runway using that mission, it would be a stuttering fest. I did not experience high GPU frametime during the test. Personally, I do not like playing without shadows since we're no longer in those dark ages of gaming but if you're in a pinch for extra framerate in VR then turning off shadows might be the way to go. I'm also going to test this in SteamVR mode and compare. EDIT: So with SteamVR OpenVR mode exact same pixel rending (3.6K horizontal), same mission (Apache Caucasus Runway start), flat shadows. My CPU FT is 29-31 ms, GPU FT is 23-24 ms. So for me, OpenXR option is still better. The juddering is also worse in SteamVR mode when fps is below 45. Strangely, juddering isn't bad at all for me with OpenXR even with framerate in the mid 30s. So far, settings that I've found that can significantly affect CPU frametimes are textures and shadows. Reducing those settings can help boost my CPU frametime by a good margin.

Would be interesting to see if your RAM or VRAM is saturated when this happens.

Yep CPU is 5.0GHz all core. Don’t remember about my GPU but moderately OC also, however the BIOS has a thermal limit so it typically won’t go beyond 70C when pushed unlike the top-end version.

Perhaps my rig isn’t as strong as yours, Don, I cannot get good fps via SteamVR at 100% on Aero’s Very High setting (that’s 3.6K horizontal pixels per eye) and typically needed around 80% downsampling for typical DCS use. For me OpenXR visual is slightly ahead at 100% vs SteamVR at 80%, although I need to check out the latest SteamVR update at some point. So I’m still going to be switching around between these two options.

Thanks. Can’t wait to give this a go with my friend this weekend, planning to do both multicrew and MP version.

The frametime numbers seem pretty bad. Were you running a default mission or something different? I typically use the Syria hot start one since it can be fairly taxing once the 2 F-16s start to roll out at the airport. I’ve seen CPU frametime that high or higher in the Marinaras when flying over the carrier, but never seen GPU in the 50s. I normally use the Syria mission to tune my settings so that I can get around 22.2 ms or less for both GPU/CPU frametimes while on the ground.

The question though is whether the RAM hogging tendency like that an intended feature or a bug?
