Oculus Rift with DCS World Discussion

[Svsmokey]

You have to tinker with the DCS settings options,

 

Also, the new NVidia drivers have "DSR factors" in the Global settings. I fly MP air battles, I cannot have 'pretty VR' I need a fast VR. "DSR smoothness" is the trade off between pretty and slow and an 'aliased' image, mine is set to 10%.

 

In DCS, no aliasing, but SSAA x2 (which is DCS superampling)

["MSAA"] = 0,

["SSAA"] = 2,

["SSAO"] = 0,

["anisotropy"] = 0,

 

in DCS VR options I have

["pixel_density"] = 1.5,

which actually is also related to supersampling. Some settings only have effect on the 2D image, not the actual Rift VR image, figure that out yourself.

 

You muck around with all these settings,

 

to start with these days the "DSR smoothness" in the driver is the easiest setting to find/compare quick and dirty results.

 

To find your personal optimum takes a horribly long time (very).

 

I get 45fps with a 8600K and GTX 1080, but this can drop down to 25 fps sometimes in heavy MP settings.

 

Your major criteria is total image smoothness of any head movement, not how pretty or ugly it looks.

 

According to Wags , SSAA has no effect in VR . Something about pre-vs-post processing .

Nvidea power "max performance" , win 10 power management "max performance"

 

With your suggestions, i move from 22 fps to 45 FPS

Sorry about not knowing what it is

Could you tell me where it is and how to set it?

 

My NVIDIA drive in 430,64

 

many thanks

I'm getting a lot of ghosting when in fly-by camera and in the Tomcat mirrors. Also, looking out to the sides 3/9, there's a lot of double vision. I've tried different MSAA settings, but it still happens even on MSAA 0. However, not as much as MSAA 2 or 4. My PD is 1.5 and I'm using the 419.35 nvidia drivers. I've also used the 430.64 drivers. Is anyone else having ghosting issues?

What are your frame rates like? Hit right CNTRL and Pause, then if they're not at 45 FPS your ASW is off.i did a totally clean install yesterday and noticed judder which I've NEVER had in the Rift. I've had it lag but not judder. When I looked at my FPS they were spiking all over from 45-90. I immediately downloaded Oculus Tray Tool and made a profile for DCS to lock in 45 FPS for DCS and it fixed it. It's possible I set something in the nvidia card settings that caused this, or the new update is not letting ASW work. Since I did that, the cockpit in the 18 looks the best I've seen it with my normal setting of 1.8, no FSAA, shadows flat, terrain shadows flat, AF at 16X and everything but civilian traffic at high.

I always have ASW off using the Oculus Tray Tool, and my fps are still at 45 when the ghosting happens. I just tried the 430.86 drivers but it still happens. I'll try different PD settings and see what happens.

Hello guys, just picked up an Oculus rift myself and new to the VR party.

So far, I have delted the Metashaders folder and FXO to try force new ones. Graphics wise I have changed game resolution down to 1080p from 1440p and picked the VR preset in graphics as I though it would be low enough to get a benchmark to tweak.

 

Joined friends server with little AI in not too much, but the game just keeps crashing before the startup has even finished

Specs are

AMD 2600X

16GB 2666MHz

GTX980Ti

 

Is DCS that bad for VR? I seem to get good performance on ACC with decent graphics too

 

Any help would be massively appreciated

Did you switch VR "ON" in the options right most tab

 

["enable"] = true,

 

Your Oculus Home needs to be running

 

or

 

Rename/backup/delete your \Saved Games\DCS <version>\

 

folder. You want a backup or KEEP if there are clever bindings in your

"..:\Saved Games\DCS\Config\Input"

 

DCS will build a a new one, in particular the

"..:\Saved Games\DCS\Config\options.lua"

file

 

Then switch the 'enable VR' on in the VR tab and see what happens.

 

After that you need a lot of tweaking to get the vision right,

 

the latest Nvidia driver in the 3D default games settings has 2 options now, the SS 2x 2.25x 3x 4x

 

and a 'sharpness slider'

 

that's the easiest now to fine tune in combination with the DCS options.

We both run almost identical specs so power isn't the issue. I also have a Pimax 5K+ I've been trying to get to run well but so far it's unusable. In trying to find different solutions for Pimax I changed my Nvidia driver back to 425.31 but when it didn't help I went back to the CV1. When I did, the CV1 stuttered badly with that driver. So I changed back to the newest 430.8x and it was smooth again. That was until I overclocked the graphics card and tried to run DCS. I immediately had ghosting in the Rift, both in the Oculus Home environment and DCS. If I didn't fire up DCS, the overclock didn't effect the Rift, only when I tried to start DCS did the ghosting start happening. Once it started I would have to reboot. Prior to rolling back the driver I didn't have issues overclocking the graphics card and running DCS so it could be a corrupted driver. Anyway, you may try redoing your Nvidia driver. I'm going to look for a program that completely cleans out the current driver and reinstall. Hopefully that fixes it. Otherwise as I said in a previous post, the image clarity in the 18 has been drastically improved. I need only lean forward slightly to make out letters and symbols on the MPCD and see texture detail that I would normally need to VR zoom to see.

Thanks for the tip.

 

So, I just got home, deleted the saved games folder as suggested. Changed game resolution to my native of 2560x1440. Clicked the VR preset in graphics option, then went over to the VR tab and the enable VR option was already ticked.

I then loaded into Cold and Dark in F-18 at Dubai, and FPS stay at 45fps, until I look to the left and FPS drop to 22.5 - but no crashes, SS in oculus tray tool is set at 0 and I'm not launching steam VR.

 

Also tried dropping resolution to 1920x1080, cold and dark at Nevada and frames were at 22.5 straight away

Ground clutter at an airfield will reduce your frames by a lot. Once in the air you'll be fine. Turn off the frame counter and go enjoy yourself.

[Kirkey_badgers]

Haha ok I shall have to try it. Would definitely like a sharper image shall have to tweak it and see

[mariner3302]

Can't agree more!! Folks get wrapped around the frame rate numbers. Just fly it!! If you have issues then things can be done but to waste time just trying to max your frame rate number is a waste of time.

 

For me, and I don't measure frame rates often, there is no difference between 25 fps and 50 fps. I use the performance tab of the Task Manager to diagnose when/if my system hiccups.

First and foremost, the resolution in settings has nothing to do with VR. You can set to 4096x3840 and it won't matter. Those settings only refer to your monitor when VR is not being used. Cockpit displays do matter and I would set it to the lowest option, 512 I think. Turn OFF MSAA, shadows, heat blur, depth of field, cockpit global lighting, terrain shadows and SSAA. Set water to medium, textures to low (to start with), basically set everything to medium when available or low to start with. Then go to the VR tab and set Pixel Density to 1.3. This is the main adjustment that has the most effect on framerate and image quality. Those settings should get you a smooth 45FPS in the single player missions. Also, 45FPS with ASW is the goal. Don't think of it like a monitor.

If these settings work start upping other settings like textures but forget about shadows and MSAA. Your system isn't strong enough. Or you can try to raise the PD to 1.4 and leave the other settings alone. It should be flyable and look good since you're new at it. Oh yeah, set preload radius to 2/3 of the max, take trees to 60%, turn off civilian traffic (low,if you must ;)), chimney smoke off, grass to like 10.

Good luck.

How do you download older versions of the Oculus software? I'm wanting to try the 1.35 version since that's the last version before the Rift S. My DCS VR experience was much better before I used the Rift S which of course forced me to update the software. Are they still available for download?

There’s no way to roll back. Try updating your graphics drivers.

Thanks for the info. I've already updated and rolled back my gfx drivers, but I still get ghosting in the fly-by camera and the wings when banking. Also, in the mirrors in the Tomcat. Maybe it's 2.5.5 and not the Oculus software.

I've noticed lots of weird melting/ghosting for a long time but had basically gotten used to it. Especially during loading screens it would geg all wacky. Recently though I stopped setting pixel density in game and now leave it at 1.0 in game and use the debug tool to set it to 1.3 amd disable asw. In the process I also started changing a setting for "adaptive gpu performace scale" to off. No idea why but it completely gets rid of all the ghosting melting for me in dcs even in the loading screens. I also always launch dcs via the "file/launch app" drop down in the debug tool as it seems the most consistant way to ensure my oculus options apply properly 100% of the time.

Thanks for that "adaptive performance" tip ! I disabled it and immediately noticed increased terrain and object shadow draw distances , and the elimination of that annoying micro-stutter when looking to the side . Gonna try the pixel thing next , but even now , i am experiencing the best graphics/performance ever :)

 

Frames still locked at 45 , though-weird !

Where is it located? NVIDIA control panel?
