Rift Judder and FPS discussion thread.

[seanwasere]

i fixed the audio issue by setting NumWorkerThreads="0" in the appconfig.xml in the folder where elitedangerous32.exe is stored.

 

[seanwasere]

I learn more about the inner workings of my pc in the ED forums than anywhere else,
so for the record,
I just experimented with HPET,
with HPET off at bios and os i get queryperformancecounter = 4.12
with HPET on i get queryperformancecounter = 4.13
I cant tell if HPET on is the same or worse in regards to judder,
but it's not better with HPET on,
so back to the drawing board

How do I Super Clock my Factory Superclocked 980 gtx to reduce Judder?

Title says it all. Been having worse Judder issues as of the last few weeks, think I have tried EVERY. and I mean EVERY guide and concept to reduce Judder. I've parked cores, purchased separately powered USB hubs for my oculus and every other thing the Guides in these forums suggest. So, now I'm going to try and Superclock my Gforce factory already factory superclocked 980 gtx if you follow what I mean.

So, since I've never superclocked in my 36 years of gaming....someone tell me how to do it please...with a good amount of detail!?!?

Thanks!

Judder here too. Also tried many things. Even overclocking my graphics card. Read many posts here about the same issue. I can only conclude its the game coding.

you have MSI Afterburner downloaded and installed ?

 

[Nurmi]

Have you checked if the GPUs are fully busy when you get judder?

If they're not, then overclocking isn't going to help. Most judder doesn't seem to be about things being GPU bound, but rather network, memory, or disk bound, or GPU being underutilized. Or that's my impression anyways.

 

[BigPickle]

Nothing will help the judder lads, I've got a 980 too and got it for this game with my DK2.

Its rubbish to see that having not played or even had the game installed since launch the same problems have not been fixed or even publically addressed so customers know what is going on with VR

 

[redmantab]

lol , well i may as well try it since it won't hurt at all right?

So, again my fellow vr friends, how do I do it?

 

[djbordie]

all depends, if your judder is caused by this or that.
certainly load up MSI afterburner and start with a gpu clock speed of +150 and memory sped of +250-350
click apply and see if stable while playing ED. worst case it crashes the nvidia driver. then lower settings and repeat.
almost guarantee you can do 150/300

this though, may not be the cause of your judder.

what is your full system spec?

all the time? only in stations? near planets? etc...

have you modded anything? ie planet textures to 8K?

so many variables for judder

are you running 1080p without dsr and without in game super sample?

980 overclocked with a 4.0ghz + cpu should be able to do IN GAME SS of 1.5 with everything on high, shadows on low
Make AO forced in NVIDIA CP, use sweet FX and turn off in game AO and AA.

that being said, 1.5 is sometimes too much for a 980, so it may take tweaking the heck out of your rig/ed to maintain that 75 fps on a 1.5 SS.

other options are nvidia CP DSR, set that to 1.5-1.78 or 2x with smoothness 15%

also try nvidia CP - physx settings - physx to CPU (if your cpu is beefy enough)

i actually switched to DSR x2 instead of in game 1.5. 1.5 certainly looks better, but i found the frame rate was dipping to 72 in the station and i just dont want that immersion breaker.

One other thing I've found that causes judder, is one of my two GPU's will get stuck at 705 or 706 MHz instead of 1100.
Once this happens I have to reboot to fix. Occasionally I'll have to actually power drain the system first (unplug, then hold in power button to drain power)

If you go through all of the above things and still have judder, be sure to check your GPU(s) clock(s)

Once both of my GTX680 clocks are at 1100MHz, I usually have a decent experience

Hey man, ... ok here's the deal.

980gtx superclocked
i7 -4790k cpu @ 4.00 ghz
16 GB ram
Windows 8.1 64 bit
Asus motherboard
1 TB solid state drive.

No mods running with Elite Dangerous
I am able to run the game as you said using Nvidia's DSR 1.5x and most settings on low with minimal judder. Mostly just in Resource extraction points and stations. So, 80 % of the time it works well. Which was fine....UNTIL last week.

All of a sudden I get this random "shaking" of my whole screen even when looking still. It never used to do this and this is different than "turn your head" judder which i used to only get when in stations or res when turning my head.

So now, in addition to the "regular" judder I get when turning my head in res and stations that still had the other 80% of the game working perfectly and I was happy enough....NOW I have this new sporadic shaking. It will be every 5 minutes or so and last for 2 minutes or so. I can reach my hands out and touch the camera cable just barely a bit and it will go away.

I don't have any intereferecne or objects in front of the camera and the setup is exactly as it has been for the last 3 months. Just so weird I get this shaking but then I can reach my hand out, touch the area in front of the camera to almost " re focus" it or something...or just unplug and replug the cable back in and it stops.

The blue light is always on as it should be and I just don't get it.

I could unplug the camera all together and play without posi8tional trackin which isnt THAT bad, but meh, I want it to work how it has.

Any thoughts?

(written quickly please bare with spelling etc)

 

[seanwasere]

You don't superclock it,
you just play in training mode,
lol,
easy

 

[xondk]

Judder, is more often then not, not GPU related, just fyi, it can usually be other combinations of factors the main one can most definitely be display.
So overclocking is not the way to go.

 

[redmantab]

New type of "shaking" in addition to the Judder most of us have. Help please?!

ok here's the deal. I have this new shaking in addition to the regular Judder we all have. Here is my situation and I am hoping some of you may have some ideas for me please!?

[djbordie]

judder is the result of not sticking to 75 fps, so in MOST cases it IS THE GPU
so in MOST CASES overclocking helps or cures it.

your rig is completely fine!
top tier.

this shaking is very disconcerting though, specially because it is new...

You understand the concept of judder and say its different, im at a loss completely. sorry.

I personally if in this situation would install a fresh windows 7 on a separate SSD drive and start migrating stuff over.
a nice clean OS always cures odd problems that cant be easily fixed.
i know its last resort, but sometimes this solution is best.

im actually doing the same atm, separate ssd with a fresh OS on it, and slowly migrating games and apps over, then when complete i will kill the existing OS ssd and should be seamless.

your obviously using the new nvidia drivers right? and nothing has changed hardware?
could be as simple as malware or anything like that. how clean do you keep your OS?

 

[redmantab]

well the ONLY hardware change is the 2.5mm or whatever size it is cord from the camera to the rift is a new one I bought at an electronics store rather than the one that came with the dk2. You know, the little cable that looks like it is for headphones that goes from the camera to the rift plug (or it can go directly into the front of the dk2 - which I have tried and I still receive the same occasional shaking). The blue light is always on and it works, except for the occasional shaking so, .... I don't think this is hardware related.

 

[Caspar]

What level of detail are you running this at? Do you get judder at all levels of detail?

I have to admit, having seen judder whilst my GPU and CPU were well under 50%, I'm curious to know what could be causing this. I'd stick MSI Afterburner on whilst playing the game and see if your GPU is actually being taxed. I even get it when in supercruise with GPU at a piddly 25%.

 

[djbordie]

may want to ask the OR people if the 3.5mm jack cable is something special or a regular audio one can be used?

id try on another OS install with just windows 7, nvidia drivers, oculus and ED...just to test if its software related or what

 

[Cosmos]

Have you checked if the GPUs are fully busy when you get judder?

If they're not, then overclocking isn't going to help. Most judder doesn't seem to be about things being GPU bound, but rather network, memory, or disk bound, or GPU being underutilized. Or that's my impression anyways.

I suspect its network related.. some kinda bottleneck.

 

[Distance]

I suspect its network related.. some kinda bottleneck.

I've always suspected most judder in the game is network related. I've not tried oculus since dk1 but from normal gaming experience I can run the game on ultra with dsr smooth as silk with my 970 but sometimes I get judder and my frames are stable. This has been more noticable in Lugh with lots of cmdrs around.

I've tested ED in the UK and the USA both with good connections but at certain times of day with other players around I still get judder at times. From using DK1 I can only imagine how much more frustrating it is for VR players.

ED are demoing dk2 at their booths all over the place and I've never seen people mention judder. Correct me if I'm wrong but I'm pretty sure they're using 980's on their demo rigs and it's the offline training missions they're demoing.

I think this is also the reason why FD have commented on VR issues as in their use (offline demoing) they don't see issues regardless of gfx settings.

Also bear in mind it's not your personal network settings to be taken in to account, you could be on google fibre but if you're connected to a player with a crappy connection that's going to influence you as well due to the p2p nature of the game.

I'm also getting this issue. The random shaking goes away if I move out of the cameras range and back in again. It never used to happen until the last patch or very rarely. Anyone else having this issue?
