Oculus Rift with DCS World Discussion

Good to see some fellow Rift S users here. I'm still a noob to DCS VR, but after I built my new PC (parts coming today!) I plan on getting into DCS VR a little more.

It can be real hit or miss. I was running a Vega64 up until recently and the rift s was very buggy with lots of drop outs. Recently upgraded to a 6950xt and it’s been smooth and stable since.  Either I had a bad card or the rift s just wasn’t optimized enough and needed the extra power. Before that I tried everything from powered usb hubs to usb-c slots.

DCS is running pretty well for me on the rift s. I'm getting some good frame rates and stable/smooth play on Caucasus, Normandy 2 and Sinai. Populated areas are the real struggle but with careful settings I get a stable 40fps (with ASW) over Cairo.

Good afternoon,

Not a writer on the forum but a reader for years.

I'm writing because a couple of days ago I upgraded my rig, except for my graphics, and today, I was trying to tweak a bit my DCS config so I have a smoother experience on the Rift S. I'm able to fly at solid 40FPS, but a lot of stuttering is happening, specially when flying low, and wanted to understand what it's going on.

Before going into further detail, let me detail my rig setup:

Intel i9-13900KF
MSI Z790 Tomahawk
DDR5 RAM, 32GB, 6400Mhz CL32
Asus Dual GeForce RTX 2070 SUPER EVO OC Edition 8GB GDDR6

I know my setup is now bottlenecked by the graphics card, but I will replace it by the end of the year (too much money to expend at one time hehe)

So, in order to understand what's going on, I wanted to test what would happen if I set everything to default and lowest as possible. That is:

- Oculus Tray Tool off.
- OpenXR Toolkit disabled.
- Nvidia Panel Settings default except for "Prefer maximum performance".
- DCS Settings: "Low" preset. PD 1.0. Using MT and OpenXR (Tried both, default and OpenComposite, exactly same result on both).

My surprise is, even with everything at low, I'm still getting stutters. I always use the "Free flight" from the F18 Instant Action to test, so I always have the same feelings. And, no matter if I turn ASW to On or Off (Using RCtrl + KP1/4), I got the stutters.  I tried recording a video but the result was varying as the recorder gets resources, so instead I'm gonna attach a couple of screenshots of the FPS window where you can see in the lower graph the stutters I'm talking about:

 

Left is ASW Off (66FPS on that moment, caused by the print screen command, It holds at 80 normally.) and Right is ASW On (40FPS)

My question is: is there something I'm missing? this is of course happening the same if I setup everything as my needs (DCS graphs, OTT, etc...). Those stutters won't never dissapear.

Are you guys experiencing the same? Do you have a smooth line with no lags? Or is this something I need to live with?

Thanks in advance and sorry for the long post.

Regards

Have you tried to switch off radar? or test with radar in AG mode?

I started a thread, I suspect you stutters in F-18 are related to radar in AA.

Micro stutters are back, I get them every 10 seconds.  Quest 2.

Guys what's best practice to running DCS with a Quest 3? 

[amigastar]

Hello,

I have a problem with my new Meta Quest 2. The Headset is so blurry in DCS that i can't even read the instruments like the Abris in the KA helicopter properly, i mean they are there but really blurry. Also when i move my head the picture get blurry even more.

Do i have to change a setting or something?

I hope someone can help me.

Make a screenshot of system and VR options in DCS. If you've made any changes in gfx driver control panels or meta gfx options set them back to default.

If I had to guess it's DLSS and sharpening set to 0 that does it to you.

It can also be low data rate of airlink.

Now you gave me an idea, maybe my Questlink cable is not good enough since it's not an original but a cheap one.

Edit: Could it be that the Meta Quest 2 has such blurry graphics? I mean when i look around the view gets even more blurry.

So i've turned off Motion Blur in DCS settings and now its clear without being blurry when moving the head with Quest 3.

[Steel Jaw]

After the most recent O2 update the whole sim is a stuttering even in the UI...

BTW, the topic title talks about the Rift (S) in DCS. For Quest headsets there are other topics.

try making sure your (ipd) eye distance adjustment setting is correct.  I found even being off a fraction can cause vision issues. Example, mine is 62.5. Also, even though it is VR try a different distance to the screen itself. I have no cluse why that makes a difference with VR on your head, but it did for me.

A good way to save VRAM with Oculus headsets is using Virtual Desktop for PCVR, now VD can launch native OpenXR game without Oculus PC or Steam VR and those are a VRAM hog

I’m not sure how much difference it really makes. Maybe if you have less the 12 gb VRAM!? I find that performance is better with oculus link-cable than VD with Quest Pro. I have a lot of experience with VD using Pico 4, and it is very good software especially since VDXR, but oculus link is a better in terms of image clarity and no difference in VRAM. I think the biggest issue with oculus is turning off oculus home.

I recently got the Quest 3 and my system isn't that bad.  I have i9 11000k with RTX 3080 and 64 GB RAM @ 3600 MHZ.  I did all the tweeking and downloaded occulus tray tool, openXR tools . Well after a months of trying to get out of this thing a reasonable quality at least close to 1080p nevermind 4k, I gave up. the image is blurry, too blurry I am afraid to ditch the flat screen. just not yet. I am about to return my Quest 3 back to amazon. Do you have any suggestions?

Really? I'm very happy with mine - I find that either increasing the resolution slider in the Oculus software to the right, or increasing pixel density in DCS to at least 1.3, the image is nicely sharp. I also have DLSS/upscaling turned off since that makes the image blurry for me.

Also make sure the IPD dial on the headset is right for you.

 I did all of that, plus you can clearly see screen door effect on this headset. I don't have problem reading what is in the cockpit, it is beyond the cockpit where the mess is, it is too blurry and shimmering. I cannot believe people actually enjoy this.

It shouldn't look like that. I get a realistic view if buildings with my quest pro and Pico 4 and no noticeable screen door effect. Have you verified that your output resolution is what you think it is? OXRTK will show you the full Res if you set it to FSR or NIS.

I used to have a rift s interested in people opinions in 2024 ?

All shimmering is gone with DLSS/DLAA but you'll have some ghosting (esp. with low fps) and blurring (you can use sharpening slider and higher PD).

With MSAA and higher PD (or upscaling in Oculus) you can have less blurring but you'll still get some shimmers, probably with worse fps.

For screendoor and resolution of the display itself you cannot do antyhing - either you accept it or not. Check other headsets if you can.

Pick your poison because no VR headset can get flat screen quality.

@freehand You want my opinion on Rift S? I could still improve the image with better card and higher PD but no way I'm going back to flat screen.

Sure I want your opinion I have owned many headsets in the past but have the chance to buy a rift s very cheap and would like to give it another go I run a 3080.
