Request help from Rift CV1 w 1080 / 1080Ti to run F/A-18C performance test.

I wonder if an Oculus Rift CV1 user with a 1080 Ti OR 1080 would be so kind as to run the following test on their system, so that I can gauge whether to buy one of these (£800+ :() cards.

And for the test itself:

Keep the HMD on your desk, we do not want its screens to activate at any point. Be careful not to accidentally trigger the sensor with fingers while moving / placing the headset.

Start Oculus Home. I'm running version 2.whatever the latest update is.

Start DCS OpenBeta 2.5.2.17978.

Change DCS settings so that they match the settings below.

Bring up the frame rate counter (ctrl - pause).

Run the instant action mission "Airfield Takeoff and Navigation", i.e. click on "FLY".

Centre the view with VR Centre. You may need to move the HMD before keystrokes register.

Let me know what your frame rate is (just sitting in the cockpit).

(optional) Do the same for the missions "Carrier Takeoff" and "Ready on the Ramp".

This would be very helpful to me. Many, many thanks for any replies. I would like to get an idea for both the 1080 and 1080 Ti.

Might be able to help out. I'm not sure what cv1 means though. I bought my rift last november

Will try & give this a go later, I would maybe hold on buying a new gfx card i'm sure a new card will be out soonish & will no doubt be second hand cards for sale.

Thanks for replying. CV1 = consumer version 1 (iirc), i.e. the release version. Previous versions were developer versions. Yours is a CV1.

Give me like 10 mins. BTW I got 1080ti poseidon

Wow - thanks :). No rush - 10 days would've been just fine.

Just curieus, why would you run oculus home first? Imo the less programs interfering the better for VR

Because "oculus home" starts automatically.

I believe it's possible to get DCS to run without the Oculus software starting up. I haven't tried it myself. Does it provide much of measurable performance improvement? I doubt it, but will try it if someone says it does.

BTW. I get 80 FPS with all settings the same, except MSAA = OFF.

I got no clue how to place a photo in the forums been trying forever lol.

O Yea I forgot it would do that, but you can disable that

If you right-click on the oculusclient.exe select properties and just set it to run in administrator mode. if i remember correctly :D

(77 fps)

Many thanks for taking the time and effort.

RE photos: What I do is go to my forum profile, create an album, upload the photos to an album. I then put links to those photos in my post.

edit - PS what CPU are you running?

Just to note, the performance of those instant start missions will be affected by a known issue where the F/A-18C Lot 20 static object. In OB they cause a huge FPS hit which isn't present in the internal build.

I was going to lend a hand (I have a 1080Ti and CV1) but it looks like you already have some takers, which is great to see. I tip my hat.

Thanks for the update. I just setup a mission north of Crimea, just 1 solitary hornet (me) flying level in a barren wasteland. All settings the same - 56 fps.

FYI unless you opt out of the beta or rather never opted in then you can check for Occulus to run as admin and the software won't start when DCS does. This is not possible to do anymore with the OR Beta

Hippo I have a 1080 and it performs very well in VR and until the next gen of HMD are available I believe it is more than sufficient. Faster CPU helps equally as its needed to drive these cards to the maximum. Edit I see your specs :)

Good luck with your purchase

"performs very well". I know it's a drag, but any chance you could run the test described, so we can put a number on that. I'd be very interested to get the fps number for a 1080.

Before ED forced deferred rendering, I would have agreed with you. Now, I'm a bit skeptical. Note that the other poster with a 1080 Ti was getting 77 fps, at minimal settings with not much going on. Start adding shadows and raising all the other eye candy, and then what? I realise that MSAA x 4 is the culprit, but for me, VR is ruined without AA. Are you using MSAA? Also imho, for VR, you really want > 90 fps most of the time.

I use 2xMSAA and 8x AF for MP and 16x in SP. I also reduce visability and have it at extreme when SP. I used a reg tweak to disable ASW permanently and this gives me fluid gameplay with even 30 FPS.

That was my settings in 2.5.1 I have not had time or inclination to alter settings while I play with the Hornet:)

Edit PD is @1.5 through GUI

Hopefully me offering an additional avenue to consider isn't an annoyance but... In the spirit of the intent behind your test, having a CV1 and 1080 myself I can tell you the FPS in the condition you described is less of a concern than these two things for VR. As a side note, as others have mentioned perhaps the F18 isn't the best baseline given the optimization and known shadow issue right now, I can attest there is a very tangible drop in performance currently with the f18

1) Pixel density / PD / Super Sampling whatever you want to call it. Being able to have at least a 1.5 setting trumps almost any other single setting. The difference in clarity is immediately apparent, this layers onto #2 below

2) When ASW (async reprojection) engages. I'll spare you the definition assuming you have a rift already, but it's a big deal. You can have a smooth flight experience overall, but during high speed passes or some intense dogfighting this can cause a warping/jittering effect on enemy aircraft while everything else appears stable.

In my opinion, #2 would be the primary reason for plunking down $$$ on a new graphics card. The ASW technology itself really muddies the value of a pure FPS number vs pancake mode. Anyways, I know that isn't what you asked but after reading your post and thinking through it I thought I'd offer something in the ways of thought vs raw numbers, however if I remember when I get home I'll give you that too :)

Personally I find fluctuating framerates (ASW disabled) in VR very uncomfortable.

Just a thought looking at your Sig. Have you turned off turbo boost and enabled an XMP profile for your RAM? It makes all your cores run at boost settings continuously

XMP yes. Turbo boost off - no. Wasn't aware of that setting - will take a look. I haven't (for the first time ever) even bothered overclocking. I'm only air-cooling.

As far as I've seen (for me, anyway) it's GPU that's the bottleneck.

Thanks.

77 fps at your settings with EVGA GTX 1080 Ti SC2 icx modded with their hybrid AIO and an i7-8700k @4.9 GHz. Problem is 100% gpu usage due to msaa 4x. Those settings are far from optimal for the 1080 ti. I recommend msaa off and cranking everything else up.

"Those settings are far from optimal for the 1080 ti"

Yes (since deferred shading was enforced). Also, DCS image quality in VR without AA is on another planet from optimal (imho).

Yeah I have to have at least 2x MSAA.

I skip msaa entirely and crank the detail up instead. Besides, 1.3 PD is already an awful lot of AA. I've been thinking about switching back to 1.6 or 1.7 PD and accepting 45 fps though. Getting 90 fps is a real problem even at potato settings due to cpu usage.
