Some tests with my 1080 and ED settings (Oculus Rift)

[stevesideas]

So I decided to carry out a few tests. I've set pixel density inside the Oculus Debug tool to 2.0

I can set everything to low inside a station and yet I still get the occasional judder.

I checked the performance tab (from the debug tool) and the comp rate is running at 90HZ but the app frame rate is 36.6Hz . If I do not turn my head but instead lean left and right whilst looking at my right hand (in game) there is a lot of judder. Just turning my head isn't too bad I guess.

Can someone tell me if they experience the same thing. I'm very disappointed with the fact that Nvidia claims the 1080GTX as a VR ready card and yet I still have major issues with ED. I'm guessing ED is not optimised that well for VR or quite simply there is just too much going on for the card to handle.

I also get a lot of dropped frames (debug tool).

Is there something wrong here or is this roughly what everyone is experiencing ?

My system is i7-4700. 32gb 1600Mhz ram. 1080GTX (founders edition).

I have a similar PC (i5 6600 4.6 ghz, 16 gb ddr4 and 1080 founders edition watercooled running at 2100 mhz)

After playing around with settings I have settled with Ultra in game, but with shadows at medium, blur and bloom off, smaa and SS 1.0. In the Oculus debug tool I add 1.3. It could be better, but its the best quality I have found personally with consistent high frame rates.

Some people run lower in game settings and SS at 0.65 but higher debug tool (1.7 to 2.0) but I personally found this gave poorer image quality overall.

From what I have read though it does seem subjective as to what looks and feels good to each person, so worth trying different things.

I was initially disappointed with the resolution, although blown away with the sense of immersion, and after a week of playing ED in the Rift I can't see myself going back to monitors.

1080GTX also here - yes, Pixel densities above 1.3-1.5 are taxing in high-poly situations like stations, and when you can see a lot of terrain (rough planets with mountains usually). PD of 2.0 is beyond even the 1080GTX.

The judder yuou're seeing is the Oculus runtime's Asynchronous Time Warp function showing you 2, or even 3 of the same frame (33fps being drawn at 90fps in the Rift). Lateral, sideways translations of the head appear to judder more so than simply turning your head (mainly because ATW can't fake each frame as well when sideways motion is involved - you end up with a ghosting of the image, which is easily seen by you).

I'm on planet in the SRV a lot at the moment and I'm running PD=1.3 with SS=1.0 in ED. It improves image quality a bit, but I only see occasional judder on planet etc, usually when at high speed in the SRV, looking 90 degrees left or right; you can see rocks nearby jumping 2-3 frames as ATW can't fix the resulting ghosting artifact.

Don't turn ED's SS down to 0.65 unless you have a real need to improve the text. Some here have noted it improves the text readability, but all other image quality is severely degraded (texture, aliasing etc). However, it does brighten and sharpen the text (downsampling to 0.65 actually functions a bit like an edge detection algotrithm in a way, so contrast is improved in text, to a point). Some others like the fact it improves the frame rate a LOT, and some like the 'crisp' kind of image. Yuk, for me its horrible. To each their own.

Yep, I'm about the same, PD=1.3 and SS=1.0 with shadows at high (I like shadows and the Ultra setting doesn't really do much past the high setting for me). Blur and bloom off, using SMAA. So we differ on shadows, is all.
My 3770K is stock 3.5GHz, so it boosts itself and sits around 3.7-3.9 when ED is running (cold in my study, winter here down under in Oz).

Well I'm running the following:
i7 5820k @ 4.5GHz
16GB of DDR4 3000HMz RAM
ASUS GTX 1080 STRIX
SSD

I have most settings on ultra, other than planet based ones, which has the terrain slider set to half way. Shadows are set to high, with Bloom off, DOF off & Motion Blur off

Before the recent patch everything was as smooth as silk, even with the debug tool set to 1.3, now I get occasional hitching no matter what settings I have applied. Even with the debug tool and in game SS set to 1.0.

Why would you not just run the game at 1.5x in Game, and leave the Oculus tool at defaults for rendering?

The Game setting is the 'source', so starting out with >1.0x will ensure a good quality image before oculus's software does it's thing. Your 1080 should have the beans to do this as my 980Ti OC can do this (maintaining 90 fps even around engineer's bases).

BTW Just curious -- How is the "CPU rendering time" for your stock 4770 (non-K)? Is it staying under 11ms, even during Orbital Cruise and landing at engineer's bases?

Is your video card plugged into a PCIe x16 slot? Check your mobo manual.

Are you using a SSD or spinning HD for the game? Textures loading in from a slow drive can complicate things.

What are your other settings though? I find the 1080 struggles in some areas even at 1.0 SS - when exiting your ship in a SRV or flying through a canyon for example. The occasional hitch while pitching or entering a station. My settings are above.

I have been playing with the debug for about a month. Tried everything from .65-1.2 all the way to 2-2. The difference is small with far away things and somewhat better with close objects. I find the sharpening more evident in DCS than ED. I think that there may be a 2 sided coin. These old eyes don't see as big a change as the eagle-eyed youth probably do, but I suspect they also see more SDE (I can hardly see it). I find I can get more sharpness out of how far I place the lenses from my eyes than the PD tool. My VR Lenses shipped today and I will be interested to see what that does for me.
I settled on .65-1.5 away from busy areas and .65-1.3 otherwise. GTX980 and I5 2550k@4.2 VR high, graphics high ,AA off bloom off, shadows medium.
If FD can get AA working properly, this may go a long way to improving things. Not that I don't love ED in VR.

Super Sampling = 1.5 (Debug Tool) - Smooth as hell, nothing stutters, nothing is slow, just warm and soft.


i7-4600
16 GB Ram
GTX 1080 - MSI
Win10 64 - Home


The gfx with 1.5 is fantastic. Better than expected. No judder or stutter. Just smooth.

Current Settings (typing with headset on.. )

hmm.. much lower than i realized. let me do some testing .

Texture = high, shadow = low, bloom/blur/aa = off, SS = 1.5, ambient = off, env = medium. fx = low. DOF, reflections high. HMD - all the way to right. Galaxy map low. terrain - medium, left bar, high, medium.

The model draw distance is minimum so i'm going to raise that and see how it goes.

Might explain a lot - those are much lower than I am using.

Most importantly - what are your other options set to?

Going above SS 1.5 (in-game only, no Debug Tool needed) with all other graphics settings maxed out produces the best results for me. I got two 1080 GTX (one Founder's Edition and one ASUS STRIX 1080 GTX OC, which is the primary in non-SLI mode. The FW card is designated for PhysX processing only and the ASUS is overclocked to about 1958 Mhz. No stability issues.

SS 2.0 works everywhere except asteroid fields, planetside and starports. There is some occasional judder under those circumstances and I could not see any visual improvement between 1.5 and 2.0 anyway.

Haven't tired SLI yet but there is really no incentive since I'm happy with the system and the visuals the way they are.

Even with a 1080GTX, I'm staying down at Pixel Density 1.2 - 1.3 with SS ingame at 1.0. Gives a noticeable visual improvement at middle distance and for text, but low fps impact.

I'm spending a lot of time on ground in the SRV, so terrain really hammers the GPU render time (looking at the Oculus debug HUD info)
