RTX 2080 Win 10

[Sadistic Intentions]

Greetings Commanders.

So, for christmas i bought myself an RTX 2080 which necessitated an OS upgrade from 8.1 to Win 10 as Nvidia aren't supporting 8.1 with drivers for RTX cards.

I took advantage of the free upgrade so Win 10 is not a clean install altho almost everything from my 8.1 install seems to be running well, almost.....

ED runs awesomely on my 3 screen 5866 x 1080 with great framerates on ultra with SS set to 1.5. My Processor an i7 4770 shows utilisation of around 75/80 % and the GPU 100% with vram usage showing around 60% on the cpuid Hardware monitor.

And then I try to use VR...

I have a Oculus Rift CV1
Any setting above VR low causes my FPS to drop to a steady 45. medium 45, ultra 45 with only small variation However according to CPUID HM my processor utilisation is only around 65/70%
GPU utilisation is only at 67%.

So, does anyone know what gives?
Is it worth going thru all the hassle and time to reset/refresh Win 10, and then re downloading and reinstalling all my software? An epic task that I would really rather avoid having to do as it seems a little bit like overkill, strawgrasping. if there is a solution that your aware of please help.
I'm a tad bummed out that after spending around $1900 aud on the HMD and card for VR to be getting such mediocre performance :S

Much appreciate any input or advice.
Cheers and tyvm Commanders!

Where are you getting that framerate? It's very hard to maintain 90 fps on planet surfaces and near stations even for top of the line systems. In other situations like supercruise, you should easily get 90fps on VR High or even VR Ultra probably. Your CPU is also probably bottlenecking your GPU. So not necessarily unusual what you're seeing. Posting your full graphics settings would be helpful. A quick way to do it would be to download Dr Kaii's EDProfiler, hit "Detect Current Settings" and take a screenshot. Here, try these settings:

Model Draw Distance Max
Texture Quality High
Shadow Quality High
Bloom High
Blur Off
DOF Off
Super Sampling 1x
Ambient Occlusion Off
Environment Quality High
FX Quality High
Reflections Quality High
Material Quality High
HMD Image Quality 1.5x
Galaxy Map Quality High
Terrain Quality High
Terrain LOD Blending High
Terrain Work Max
Terrain Material Quality High
Jet Cones High
Volumetric Effects Quality High

These should provide a decent baseline. I know shadows hit FPS pretty hard. The terrain related stuff mostly relates to planet surfaces so you can tweak those for that. HMD image quality has the most effect on FPS...it's basically supersampling, but using Oculus' internal version, per pixel override. You can bump that down to 1.25x for a big fps increase but less text sharpness.

Thanks for getting back so quickly mate, much 'preciated

I seem to be getting 45 fps everywhere while in HMD irrespective of settings. Low quality, high quality, ultra, doesn't matter 45 fps. In stations or out in the boonies 45fps. It's as tho something has capped it at 45.

In ultra with SS at 2 and using 3 monitors @5866x1080 I get around 45-50 in stations and @120-130 fps in the boonies.

If CPUID hardware monitor is reliable then it isn't a cpu bottleneck causing the low framerate in HMD, as it shows much higher cpu usage using monitor displays than it does using the hmd. It also shows 100%GPU usage using monitors and only 67% in HMD.

I will d/l that profiler, mess around a bit and get back to you..

Hmm, if you can't get 45 fps in supercruise at any setting, then something's definitely off. Does it EVER go above 45? It sounds like you're stuck in ASW. Do you have Oculus Tray Tool installed? It'll let you force ASW or turn it off completely. It also has a performance overlay that will let you see your actual frame-rate while in VR.

 

[Sadistic Intentions]

I have the debug tool is that the same as the tray tool?

Cearly something is up the creek tho.
Using these settings https://prnt.sc/m98ar2

This happens https://prnt.sc/m98ab9

Temperatures are fine so no throttling, CPU utilisation is 32% (use a core parking manager to prevent parking and force turbo)
GPU nice and cool, only 48% utilised and vram 70% used. Yet only 45 fps.

This is why i wonder if it's a windows thing due to it being an upgrade and not a clean install?

I'll play with the debug tool a little and then most likely throw the whole lot out the window. :O
This rig ought to manage 90 fps quite easy but as it is it's running no better than it was with my old gtx970

 

[cmdrrdmc]

Debug tool offers many of the same functions...not sure if it has the performance overlay.

Ok so you have 1.25x supersampling, and then on top of that 1.5x HMD quality, which is supersampling again. I believe they are multiplicative, so you have effectively 1.875x supersampling AND you're just outside a station, so getting only 45 fps makes sense. You're in ASW. I suggest you set supersampling to 1x, HMD quality to 1x, all other settings to medium, and see what you get. After that, start adjusting HMD quality. DON'T TOUCH SUPERSAMPLING. It's not good for VR. HMD quality is the supersampling you want to use.

Forget the VR presets, they suck balls and make no sense.

edit: BTW, just to give you some perspective, the Rift render target is 2700x1600. You're supersampling that by 1.875 times. That's almost twice as many pixels as 4K.

 

[cmdrrdmc]

I just realized I should have asked...do you know what Asynchronous Space Warp (ASW) is?

 

[Sadistic Intentions]

I wasn't really upto speed on SS and HMD quality so thanks for that. Although that was a bad example of my settings as even using the VR Low preset, I still get 45 fps.

However it doesn't matter whether I am out side a station or alone in the ether I still get 45 fps. I understand what your saying but even so, my processor is only at 32%
My GPU is only at 48%. Are you saying that with ASW it's either 90fps or 45fps with nothing in between? b/c that might make sense although I struggle to understand why that would be desirable.

I am aware of ASW but obviously not fully understanding of it. I tried to read up on it but it went a bit over my head
Why is 45 fps better than 75?

Shouldn't either the cpu or the gpu be pushing 100% depending on which one is the bottleneck? As I said when i'm using my monitors my cpu is at @75-80% while the gpu is showing 100. So it seems that my cpu is fine for my gpu and its the gpu that is limiting my framerate

I feel like I must be stupid or totally missing something lol. Thanks for your patience..

ASW will half the FPS basically doubling/interpolating frames in Order to provide a smoother experience when the target 90 in your case cant be held steady.
If the FPS bounces between 75 and 50 and is unpredictable it casues nausea for alot of people and also cannot guarantee correct frame times per eye.

When your system limits to 45 it is underperforming so it can deliver steadly. Also using HMD & SS -> disable all Supersampling methods and HMD scaling and test again. Supersampling renders in higher resolution and scales down - basically a form of antialiasing. This is VERY VERY Memory Bandwith intensive. Also if your GPU runs out of VMem it will utilize your slow system ram to copy back and forth - this also leads to massive bottlenecks and frametime discrepancy - which in turn enables frame interpolation again.

Fact is your System is not powerful enough to run at that rate@90fps - first lower all suersampling settings then try again disabling also AA if needed. If the target can be reached it will peak up again and cpu load will also rise.

At this high supersampling that you have set with HMD and monitor its has taxing as rendering 2x 4k which the 2080 has neither the compute power nor memory nor the bandwith for. a Vega VII with 16gb HBM is a totally different thing for something like this - however, the compute power will also be taxed in this case.

Also keep in Mind not only your cpu can be the bottleneck but also your memory and how fast it can deliver data. However on that System your ok with that kit and i would try to avoid blowing the GPU VMem instead. DDR3 1600 with good timings still is pretty decent when the GPU isnt using it also.

Cheers!

When in VR, what resolution is ED running on the monitors?

This does drastically reduce framerates. Have you tried EDProfile?

I had the same issue with my 1080 but now it runs sweet.

 

[cmdrrdmc]

Thalion's answer is good advice. Just to clarify a bit more in layman's terms, when you can't hit 90fps in a game, Oculus' software reduces it to 45 fps. But for every actual game frame rendered, the Rift software generates another frame based on the data in the previous two frames. It's basically the software's best guess at what that frame would have looked like if you really were getting 90 fps. This allows the headset to receive a 90 fps image (although half these frames are not actually coming from ED but rather Oculus' algorithm). The result is much smoother performance at half the optimal 90 fps frame-rate. The downside is Oculus' guess isn't always perfect because it can't know what the actual frame would have been, so you can get some artifacting. You can also get a bit of judder when ASW kicks in. Overall, it's a nice feature, but has its drawbacks. Finally, ASW doesn't just interpolate frames, it also does the same for head tracking and position (if it didn't, there'd be a large mismatch between your tracking data and the generated frame which would probably be disorienting).

So, for christmas i bought myself an RTX 2080 which necessitated an OS upgrade from 8.1 to Win 10 as Nvidia aren't supporting 8.1 with drivers for RTX cards.

Are they really not supporting the RTX cards on Windows 8.1?

The nvidia driver download selection for the RTX 2080 does only show Windows 7 and Windows 10 but I reckon if you downloaded the one for 7 that would include the drivers for 8.1.

It doesn't make sense to me that they would have drivers for the old Windows 7 and not Windows 8.1.

Unless you explicitly wanted the DX12 support that Windows 10 gives there would be no need to move from 8.1 to 10 just to use the RTX 2080.

I couldn't find any documentation to say they were Windows 10 only either.

Or am I missing something?

 

[Worminator]

I don't know if this is still an issue but since you just installed Win 10 it is worth a look. Some time back there was a windows update and some of the game mode features were turned on by default and it killed framerates. If I recall the game DVR in particular caused a lot of issues. Go into windows 10 game mode and make sure everything is off.

 

[Sadistic Intentions]

Thanks for the great explanation mate, the fog is beginning to clear. Sadly tho, even with all graphics settings set to minimum values or even off, I'm still only getting 45 fps.
I'm starting to wonder if I might have a dodgy headset now because the left earphone has stopped working as well. and no I didn't throw it out the window.. yet.

1280x720p and yep tried the profiler.

Thanks anyway tho!​

Win 8.1 only has around 2% market share while 7 has truckloads more. I cant find the announcement from nvidia right atm but yes they have definitely dropped support for 8.1.
The win 7 drivers did work but you had to manually install them, GF experience refuses too. They don't support the new mini display port in win 8 tho and didn't seem particularly stable or optimised.

Thanks for the great explanation mate, unfortunately even with everything off or on min settings I'm still only getting 45 fps.

Thanks for your reply. Yep had a look, turned it off, made no diff. :S

 

[cmdrrdmc]

Ok, so just to confirm, even at 1x SS and 1x HMD and while in supercruise (not near a station or planet, just flying out in black space), you can't break 45 fps? Also, did you get tray tool and check the performance overlay? I'd be curious to see what happens if you enable it and turn ASW off. It should allow you to see the actual frame-rate you're getting in the game.

IDK how attached are you to your old system installation but do yourself a favour and do a clean install. I wouldn't trust these "upgrades" with a ten-foot pole. As for VR it is a never-ending beta so you will be better off starting from scratch. Look at it this way - at least you will get the newest versions of software required for VR. Also headset and fps count don't have anything in common, unless you switched to pimax 5k+ with much bigger resolution ;-)
Defective headphone on the other hand - try to replace it on warranty. Alec Turner had success in doing that. Good luck.
