Rift Judder and FPS discussion thread.

[MACMAN86]

DSR=Down Scaling Resolution found in latest Nvidia driver with Elite spec settings. Mine is 2x for 2715x1527 to 1980x1280 but can't use SMAA as it crashes on hyperspace. It was designed to replace the need for AA all together so you should set all other settings on High, Ultra, Effects etc ON.
GTX970 with Dell T5400 twin quad 3GHz 16gb ECC RAM (no Rift) and still get stutter on any settings.

Macman, thanks for your reply it was helpful! This is a thread for rift users so I have to ask the rest of you rift peeps...

These options are in the Nvidia control panel when you select Elite Dangerous and then adjust the 3d settings.

Maximum PRE rendered frames 1 , 2, 3, or 4?

Virtual Reality Pre rendered frames 1, 2, 3, 4.

Some online say more. some say less. Which is it for both fields??

I really wish I had something decent. At the moment I'm attempting to build a computer to replace my tablet, so far I have a video card, the NVidia GTX560. It's very likely folks in this thread have retired more powerful parts then I'll have available within the next couple years.

Current plan is to build a new rig for Elite: Dangerous though I am limited by a fixed income and expenses that eat most of that income.
Video Card: GTX560 from a friend's closet.
Motherboard: Unknown, pledged by a friend to be shipped early January, with CPU and Memory. Exact configuration is not yet known but reported to be within Elite's recommended spec range.
Case: ???
Hard Drive: ???
PSU: ???

My current rig prefers seamless mode to full screen, mostly due to the nature of it being... a Windows 8.1 Tablet.
Sandy Bridge Atom CPUs seem able to handle Elite: Dangerous at minimum specs. I can even turn on some of the effects occasionally.

I may not belong in this thread, upon further examination...

on a GTX 980
I currently run 1.2x DSR and most settings maxed out, including SMAA on top of the DSR.
Shadows turned off, reflections LOW, of course blur and bloom off, galaxy map to medium

I get consistent 90 FPS inside stations, galaxy map is 75+ as well, outside stations 90+
I have 1 second judder/lag whenever I kill an enemy. That's a bug I guess as FPS drops from 120+ to < 75 for a sec

It is possible to increase the DSR to 1.5 with only minimal graphical advantages.

A big MUST NOT is borderless mode. FPS stays high but still judder. It seems like the low persistance modes of oculus only work in full screen (for me)

What a difference! My game runs better now and looks MUCH improved. I definitely prefer the ultra/ high settings for some and it looks amazing.

STILL, the ONLY area I get judder is when I'm in a mineral extraction zone where there are about 25 npcs flying around and then I am getting a good deal of judder. ANY TIPS ... or am I stuck with that even thought it plays and looks amazing elsewhere!??!

I don't seem to notice much different when turning it on and off. It proves quite difficult to see through the rift when it is the only display. it gives a weird affect. How do the people around here do that by the way and still navigate the desktop?

Its unclear to me if running a second monitor itself causes any performance issues, but there is definitely an issue if your monitor cannot run at 75Hz native. Recently my main monitor died, it used to be able to manage 75Hz if I knocked it down to 1280x1024 (which was a pain in itself), so switched to my back up that does not support 75Hz at any resolution. I refuse to use various software solutions to force the monitor to 75Hz as i'm not willing to risk damaging it. However being that the main monitor can only achieve 60Hz I believe this causes the Rift in extended mode to also be forced to 60Hz which is obviously bad as it removes low persistence mode.

The solution then in this case is to disable the main monitor completely when the rift is active. This can be done in the nvida control panel and is automatic when you switch the rift on. In order to then switch easily between the main monitor and the rift I use Windows+P keys to bring up the 'project' display mode. This generally gives 4 modes, primary screen, duplicate, extend, secondary screen. To switch screens from Rift to monitor just select either primary or secondary (you can use cursor keys and return/enter to select), whichever is considered to be you main monitor. To switch back just do the same thing, but select the other primary/secondary option.

Is anyone getting flickering when down-sampling or using DSR?

I made a guide here that was working just fine, I used it for weeks - now for some reason I get flickering when selecting either 2k or 4k resolutions.

I also tried to enable DSR in Nvidia control panel.

Does anyone else get this?

 

[thebjoern]

I actually just used your guide yesterday to set up my DK2 (on a GTX 970 SLI system), and it seems to work just fine [thanks a lot for that guide btw ]

The only issue I had initially was those kinda black blobs on the universe background (what's the technical term for that?), but that was before I enabled supersampling, after that it was somehow gone and I am not sure why.

 

[NoshDaMinsk]

Only in direct mode - which I have given up on.

In extended mode, no prob with 344.75 drivers...

Nosh

Or switch on the DK2 and in the NVIDIA Control Panel-->set up displays, de-select the desktop monitor and apply... the desktop monitor will switch off, the DK2 stays on. Now switch off the DK2 with the button on the top, the DK2 will now be off and the monitor with automatically come on. Switch on the DK2, and the monitor will turn off... Simples.

If I manually set the resolution higher, I'm fine. If I use Nvidia DSR from the control panel I get horrible, unplayable flicker and occasional double images.

 

[MACMAN86]

No but is crashed on hyperspace. Don't use SMAA or go all the way to OFF. I use Experience and not Control Panel as that is for all Windows.
Flickering when using Freetracknoir whilst the CSV was not updated but ok now.

 

[SlackR]

Disabling the monitor and / or plugging in the power adaptor has worked for some

DSR=Down Scaling Resolution found in latest Nvidia driver with Elite spec settings.

Latest Nvidia Driver?? I thought the latest one doesn't work with ED. Which one are you using?

 

[Chris Dettmar]

I get horrible flicker too, but I have my DK2 set as the secondary monitor. I did try it as the primary monitor and then it didn't flicker, but the colour/brightness was completely messed up instead.

EDIT: I should add that this is with SLI only. It's absolutely fine if I disable SLI. I assumed that this was a question about SLI and DSR together.

 

[Phier]

I have my OR resolution manually set via the control panel, set as a secondary monitor, and using SLI without any issues. It just shows how tweeky you need to be to get this to work right. (Actually its set as my tertiary monitor, I have 2 regular ones set up too).

 

[NoshDaMinsk]

No problems with DSR or flickering.....

Here is my way of setting up my rig.......https://forums.frontier.co.uk/showthread.php?t=88023

Thanks Hadron - works like a charm +1

You're welcome

Just going in the discussion in a branch direction. Why is this game so intensive in GPU? Apart from the asteroid belts, who can be the most admitedly power-demand, the rest of time, and with no more than a few ships in range, seeing a star, some planetary lines, and a star background shouldnt require the Nvidia beasts that everybody is needing to play at consistent 75fps in the Rift, dont you think?

I have played to Skyrim in a GTX 550Ti at medium specs, and in a GTX 760 at full specs, why on hell we need a 970 or 980 to play this on Oculus? I honestly see a lot of improvement in the game engine is needed to work fast in the Rift. I think lot of games that are supporting the Rift are doing very little compromises in the deep changes that probably their game-engines need to optimize the Rift experience, and I am afraid Elite is one of those.

And apart from this, I think that Elite is the best implementation ever of a big game for the Rift.

Do anybody see feasible future updates of Frontier improving performance for Rift? Or going to Pascal architecture is the only way to get rid of judder...?

Its unclear to me if running a second monitor itself causes any performance issues, but there is definitely an issue if your monitor cannot run at 75Hz native.

Maybe thats why I have no problem with 2 monitors and Oculus at the same time running. Both of my monitors are 120hz.
