Is my GTX 1080 the issue?

I've been chasing down stuttering and dropped frame issues ever since I built this new gaming rig. i7-8700k (4.9Ghz)/16GB @ 3200Mhz/GTX1080/SSDs with Rift CV1. So far I've pretty well been limited to .75SS/1.25HMDQ with med/high settings, shadows and AA off. I've read every guide I can find, played around with every combination of settings, old drivers, new drivers, ASW on/off. I'm using Windows Defender for antivirus at the moment so I know it's not the common AVG issue, I don't have MSI Afterburner (am running eVGA XOC), I tried disabling hyperthreading, registry edits, etc. I still seem to have pretty terrible latency (avg 25ms) and app rendering timing seems to be the most prevalent source of dropped frames. Out in space everything runs great, very little issue or complaint. Come in near a station, especially a coriolis, and it all goes to hell, most definitely so when the station services screens are up. CPU utilization is rarely more than 40%, ram usage is less than 6GB on average, GPU near stations is around 60-70%. I'm lost. Considering just upgrading to a 1080Ti and starting over, but concerned it's a hardware issue or a simple setting I'm overlooking.


Any ideas?

*Edit* I was running this card in an Alienware Graphics Amplifier enclosure on an Alienware 17r4 before, and while the CPU was the bottleneck on that setup, I was having similar stuttering issues and response times. Hence why I'm leaning a little bit towards it being the GPU.

*Edit 2* Adjusted USB connections as well as some of the power settings and it made a significant improvement per post 8, though I still don't seem to be reaching the performance others claim with less hardware.

Greetings,

My five year old custom designed computer using an Nividia N690 GTX 4GB video card runs this game perfectly using an Intel i7-3930k Six-Core CPU. No dropouts or any issues. Amazing graphics even in the current Beta. I have two running in SLI mode for Adobe software in my audio/video business but only needs one of them playing Elite Dangerous. I can stream YouTube videos on the second monitor telling me how to play the game while I'm live in the game on the first monitor. No dropouts.

While I don't have your answer per your much newer and faster hardware it is not about your video card abilities. Hope this helps a little to look elsewhere for a solution.

Regards

Have you capped your framerates? I seem to get odd stuttering in the live build if my frame generation is capped at a different rate from my monitor.

With regard to the Amplifier, the AW17r4 CPU wouldn't be the only issue - the PCIe link could well be another - Dell have been a bit... cheeky recently with the number of PCIe lanes that are dedicated to the GPU on both their Alienware and other laptop lines. They have claimed it to be an x4 link, but depending on the CPU generation and specific model, it can be an x2 link. You can use CUDA-Z, CPU-Z or Speccy to confirm. Moreover, even an x4 link might bottleneck if you're running at the high refresh rates required for VR.

Have you tried the beta yet? I've noticed non-trivial performance improvements and much better frame timings in it - to the tune of 10-15% better frames in instances with a capship drydock.

What network card and driver version are you on?

Tp-link t6e wireless card. Been considering whether or not it's network related. I run pretty much only open, guess I could check and see if it does it in private. Wireless driver or GPU driver?

Definitely good info, and kind of reinforces why I ended up building this rig to get rid of that. But that Im having the same issues makes me concerned it's the hardware since the GPU is the only common piece.

Uncapped framerate. Haven't spent much time in the beta yet.

USB. Swapped the connectors around, moved one of the sensors to a Type C connector, changed ports, etc. Also tried a suggestions I found earlier today about disabling USB selective suspend in the power settings, and even a suggestion that was PM'd to me about disabling fast turn-on for the power switch settings (I'd love to know the troubleshooting that went into that one). Results so far are about a 5ms improvement in latency and dropped frames are about 10% of what they were before. In other words, massive improvement. The interesting thing is my performance headroom still drops to around 0 while in stations, but almost no dropped frames unless I force 45fps through Oculus Tray Tool. On auto it's much improved, but I may just leave it off. Think I can play with the in-game settings some more and keep it above 0% headroom while also improving the overall quality a bit. I'll test out the network connections and open vs private tomorrow.

Many often listen to a manufacturer's hype telling them their computer won'r work unless they have the latest greatest version of their hardware. Often it is more emotional than logic per spending the big bucks. But go ahead it it makes one feel happy.

I don't have a solution either, but the specs of your hardware cannot be the problem. I've run a DK2 on my AMD FX-4300 and Nvidia GTX970 on medium settings which has always run well (that is to say no frame drops or stuttering). Of course the settings were medium.

On the same hardware setup, I'm now running a PiMax4K. This time though, I can set Elite to VR Ultra and it runs fine. Which leads me to think that the problem might mostly be caused by the Oculus drivers. You've probably already tried, but perhaps you should prioritse them in Windows. And of course shut off game mode in Windows if you have that turned on.

Good luck commander.

Prioritization is one of the first things I do when I fire it up. Game mode is turned off. The USB changes I made last night were a vast improvement, haven't started adjusting in-game settings too much yet but I know I'll be able to bump some of them up to High/Ultra now. I've been switching back and forth between Oculus and Steam and there is definitely a performance hit when running through Oculus, albeit slight.

It "worked" fine with the 1060 I had on my laptop, it's mostly emotional, I just like fast things and want to be able to turn settings up if they're available :D The dropped frames I was getting were the main concern, not the detail level.

I’m not sure if you missed the point about him dropping frames using a CV1. But if ‘Logic’ makes you happy with technology four generations old all the better for you.

OP, how are your temperatures and airflow ?

Airflow is good as far as I can tell. I'm using a Corsair H100 on the CPU and stock fans on the eVGA 1080. GPU temps are controlled through the XOC tool and I have the fan curve set pretty steep to keep temps at the lowest available target of 60*C. I almost never see it get higher than that.

I have a similar setup to you. i7 8700k at 4.7 (muti-core enhancement on) 16GB @3000Mhz, Samsung Evo Nvme 250GB (I have found Nvme to stop stutter dropping out at stations), EVGA 1080 FTW. I have VR ultra default setting but changed AA to FXAA and SS to 1.0 and HDMQ 1.3 or (1.25 can't remember what the setting it allows is). I turn off ASW to stop cases where the headroom gets too low kicking in ASW (like when looking at station menus) and for the most part I get solid 90FPS everywhere. Maybe the odd drop into the 80's but never for long.

I am effectively running higher SS settings around 30% higher than you with no really problems, so whatever your problem is buying 1080Ti isn't going to solve it. The only thing that I can think of is you have Game DVR set to record in the background in the windows gaming settings. That will crush your frame rates and I believe is the default setting.

Do you get any performance issues in 2D?

Tried reinstalling Oculus software and the game? Reviewed all background processes running?

I don't play much in 2D, usually just a quick run between stations my PMF is at. But no, the times I have been in 2D, I have not noticed any graphics issues. I've had a number of reinstalls, including fresh OS installs due to mild stupidity on my part in one case :x

I'm not running an nvme drive, which was an oversight on my part when I built this system, but I'm seeing very little drive activity on system monitor while in game, so I'm certain that's only a fraction of the problem if any. I'll be back in-game shortly and test out higher SS now that the main source of stutter and dropped frames appears to have been solved. Definitely no Game mode or DVR running, I've always had them disabled.
