VR FOR THIS SYSTEM

[Sandman3838]

Good day everyone,

 

I’m hoping someone could throw a little help my way.

I know that there are others out there that have asked this, but I’m including my system information and price of between $300 -$600. 

Oh I should mention that I'm only interested in VR for simulators. 

 

Quest – Any Low/High recommendations for a VR headset, IL2 Great Battles Series and Flying Circus?

 

Quest - Have any of these VR setups have the ability to Flip up off the eyes or switch out of VR to the desktop to see the keyboard?

 

=================    SYSTEM INFORMATION -WIN 10

ASUS Prime X470-Pro AMD Ryzen 2  AM4 DDR4 DP HDMI M.2 USB 3.1 ATX Motherboard

IL-2 in VR is quite demanding in CPU terms. This processor is a bit weak for that purpose.  I think you will need to adjust the IL-2 settings and to activate Motion Smoothing (half of the frames are invented based on trajectories of moving objects).

 

The 3060 card is also in the low segment so you will not be able to run very high resolution, so the HP Reverb G2 is discarded.

 

I would go for a VR device able to run at 80Hz, so the CPU/GPU will be about 11% less than in a 90Hz device.

 

My recomendation is a second hand Rift-S (about 150€) or second hand Valve Index just headset and 1 basestation (about 500€+100€), both are able to run at 80Hz.

That video card is too new.... 

Could recommend a CPU.   

Say a    AMD Ryzen 9 5900X   and better??

Also keep in mind with some of the higher resolution VR devices one can always run it at lower resolutions to compensate for that.

But yeah that CPU I would not expect much out of it for VR. Going to be a bit of a struggle. Reverb G2 is a great headset for flight sims, and also can run it at 60 Hz as well - some find this acceptable and some do not. But is an option and can help.

You have a Mobo which is compatible with the latest Ryzen Zen3, so I would go for the 5800X3D which showed a good performance in IL-2.  The 5900X is also an option but it ouwld be on pair on performance with the 5800X3D.

Hello i have rtx 3060 ti gpu which is almost the same as yours and i only fly il2 with Quest2 and G2.

So in case you get a decent CPU I dont think you will have any problem to run your rig with Quest2 or G2.

 

First off all i think that a final resolution of 2700x2700 in stemvr is enough for playing IL2 in VR and get some high FPS.

Especially for IL2 you dont need higher resolution because you will loose some of your spotting ability (dots size gets smaller the higher the resolution you go), you will not have far more better-eye candy image with higher resolutions than that, you squeeze hard your rig with higher resolutions and get low FPS which is quite important for happy flying. Of course with higher resolutions you have a little better identification, that's true, but you will get used to identify planes the more you fly with VR.

 

In my case i started playing with Quest2 but i now finally play with G2 getting almost steady 90 fps the most of the times.

Although Q2 gives me more saturated and clear image but more shimmering, i prefer to play with G2 because I get higher and more steady FPS with my rig..it seems that G2 works better than Q2 which has to video compress the image via its usb3 port.

 

Of course there are some trade offs in order to match rtx 3060 ti with G2 which are:

1. As i said i fly to 2700x2700 steamvr resolution- No need more than that

2. Shadows low

3. Mirrors off

4. Clouds quality to medium

5. Preset graphics to ultra

6. Draw distance to 40 km ( that setting eliminated stuttering to zero level, I guess due to low VRAM quantity of rtx 3060 ti 8 GB?  )- ok it makes quite difficult to navigate but you can get used to

7. AA to 2xMSAA , I know its an FPS killer but it eliminates shimmering i get when i play with Q2. In case of G2 i think you can set it to zero so better for your fps, in my case i 

   left it permanently to 2xMSAA. 

8. In game sharpness set to zero.

9.In game Draw distance set to 0

10. i use FSR upscaler with : a. upscale set to 0.8 , b. sharpness set to 1.00 , c. radius to 0.4 , its vital to use that upscaler!!

11. In wmr portal i set headset to 90 hz not to 60 hz which gives me more flickering image and headaches 

12. No motion smoothing , no reprojection

 

As a conclusion i think you can run your rig with G2 and rtx 3060 with a new CPU and some trade offs.

I am glad to see you are able to run the G2 with the 3060Ti, the upscaler and some settings adjusts. It is a great achievement.

 

According to Passmark:

the 3060 has a score of 16992 based on 3778 samples

the 3060Ti has a score of 20281 based on 3931 samples. 

 

So it is about 19% more powerfull than the 3060.

 

In your settings you use 2700x2700, that is about 75% supersampling, so in order to have same performance than you he will need to decrease the SS to 60%, so the visual quality would be a bit lower.

 

Here I produced some picture to understand how SS works and how add details to the image above 100%:

 

Also here you are some examples of the SS influence with the Reverb G1 (which uses panel resolution than G2 but SS number is different).

The equivalences for SS of G1 vs G2 are:

100%(G1) = 50%(G2)

188%(G1) = 100%(G2)

300%(G1)= 146%(G2)

 

Regarding the VRAM (8Gb), I don´t think this is a limitation for the 40Km draw distance (maybe another factor but not VRAM).

You can track the amount of VRAM used with MSI afterbuner and you will see that you are under 8Gb with your settings.

Thank you very much chiliwili69

very informative what you said! i always follow your posts and get great help from them.

Hi Sandman3838,

 

I also recently started playing IL-2 in VR. I spend some bit of time researching, tweaking, tuning - the comments made by others pretty much align with my experience.

 

My initial hardware and settings i landed on below:

- PC: 5600X O/C ~4850 (undervolted w/ PBO), 32 GB RAM, Asus 2070S Evo 8GB O/C Boost 2085Mhz

- VR: Quest 2 72Hz; RenderRes 4224x2128; Link cable

- ODT: FOV .80x.80; ASW-disabled; Dist Curve: High; Encode Res: 3648; Encode bitrate: 500; Link Sharpening: Enabled

- IL-2: Pretty similar to dgiatr's post but with FXAAx4

- Mods: fholger's openvr_foveated (openvr_fsr kept getting randomly disabled by SteamVR)

- SteamVR: 100% (no scaling)

 

I kept bouncing between 90Hz ASW-enabled and 72Hz ASW-disabled - As i am somewhat sensitive to lower refresh rates in VR and after about a month of fairly solid play, i decided to bite the bullet and pick up a RTX3080 10GB with the following changes:

- PC: Asus Rog Strix 3080 O/C 2055Mhz

- VR: Refresh rate: 90hz; RenderRes: 4864x2448 (consumes up to 9.7GB of VRAM)

- ODT: ASW-disabled; FOV: .90x.90

- IL-2: MSAA set to 4X; clouds: High; Distant landscape: 4x; Horizon Draw: 70KM; Distant Bldings: Off; Grass: Off; Canopy Reflections: Detailed

- Mods: None - for me, the trade off in clarity was no longer worth the performance gain

 

I still have brief but tolerable dips into the 40fps range when near the deck with towns/cities, and sometime when there is alot going on at altitude (air battles with numerous aircraft involved) - however now the control of the aircraft is always smooth and the the clarity of terrain, other aircraft, clouds is noticeably better. I was initially discouraged as i naively thought upgrading to the 3080 would be a panacea - it of course was not for me, VR is very demanding on all PC resources. 

 

I think that aspects (distance detail, sharpness, refresh rate, etc.) of what constitutes a good VR experience are weighted quite differently by individuals - as such my settings may be good for me and less important to others. I tend to prefer the high render resolution but without ASW enabled.

 

The stress test that i consistently used was a mission from one of the campaigns (Hell Hawks Over the Bulge); i think it was the New Years Day one - gets really busy at the start of the mission (Nazi air attack on the air base). I used fpsVR to monitor the experience.
