CraigFoulkes Posted April 10, 2020 Share Posted April 10, 2020 (edited) My spec RTX2080TI 16GB DDR4 CORSAIR CX550M PSU So I'm experiencing some issues while I'm in VR . Ithis is a new pc build from a uk company called SCAN. ( Feb 2020 ) I'd like to note that everything was running perfect with NO issues at all for 38ish hours. Total pc usage is approx 100 hrs use I turned my pc on one afternoon Oculus did an update I went on VR and as soon as VR display loaded my GPU started to buzz and the oculas display was all flickering So if you load in the F18 " instant action " 2and one down start on the ramp. So cockpit instruments are a little fuzzy around the edges untill I lean forwed. Look left/right the edges of there other aircraft are all flickering taxi lines and trees in the foreground also. The graphics look as they should when not in VR I have contacted Oculus about this they have had log files twice cant find anything but are still investigating. THINGS I HAVE TRIED SO FAR uninstall / reinstall Steam and DCS Uninstall / reinstall Oculus Installed latest Nvidia drivers Reverted Nvidia drivers Installed OTT set frames to 45 and PD 1.5 and 1.4 Did a factory restart on my PC I plugged a tv/monitor in to my HDMI on my GPU ( where I connect Oculus ) the display is all perfect I have tried my Oculus on a Friends PC my Oculus works as it should on his PC I ran a stress test on my GPU temps holding at 72 Changed settings many times in Nvidia Control panel Tried stable and Beta DCS and Oculus Nothing I did impacted on my vr flicker This issue is there on Oculas Apps/Games and DCS Any help, pointers or Ideas I'd be grateful I have been trying to figure this out for a week Edited April 10, 2020 by CraigFoulkes Link to comment Share on other sites More sharing options...
dburne Posted April 10, 2020 Share Posted April 10, 2020 Have you tried a clean install of the Nvidia drivers using DDU in safe mode to uninstall ?

CraigFoulkes Posted April 10, 2020 Author Share Posted April 10, 2020 (edited) Hi, what's DDU ?? No I haven't tried that but I assume I went a step further by doing a factory restart on my pc ? Fresh install out of the box pc ? So quick update just watched a video on YouTube regarding the DDU, followed the instructions and reinstalled all drivers, no change at all. But thanks anything is worth a go, Edited April 10, 2020 by CraigFoulkes Link to comment Share on other sites More sharing options...
dburne Posted April 10, 2020 Share Posted April 10, 2020 Re-reading your post: The GPU starting to buzz really does not sound good to me. Did it buzz long? Does it still do this? I don't guess you have another GPU you could try? You have ruled out the headset, so obviously it is not the problem.

CraigFoulkes Posted April 10, 2020 Author Share Posted April 10, 2020 (edited) No other GPU unfortunately, but I have tried my oculus on a friends PC and my oculus is performing as it should. He as a GTX 1060 3GB Yeah the buzz starts as soon as I losd anything in VR then goes away after I quit VR. Just to add I have just tried my friends Oculus rift on my system and it's the same flickering image in the head set, Its flickering under the trees and like jagged around other aircraft. Now changing settings the picture quality is improving getting sharper etc... but the flickering and jagged stuff still remains Edited April 10, 2020 by CraigFoulkes Link to comment Share on other sites More sharing options...

The fact it looks fine on another PC I am afraid points to maybe a failing GPU. Especially after you tried your friends Rift on your PC and it has the same issue. Can you tell for sure the buzz is coming from the GPU?

Oldahpilot Posted April 10, 2020 Share Posted April 10, 2020 Open the case and check all the connections with the Graphics card, some have 2 cables from the power supply unit for the more powerful cards, could be one has worked loose. also check the fans are free to spin without any cables resting against them (that would give a buzz at higher speeds). check the GPU is seated in its PCie slot correctly.

Oldahpilot Posted April 10, 2020 Share Posted April 10, 2020 One other thought, when I fitted my last GPU, the system reverted to using the on board graphics chip because I hadn't quite got the card fitted in its slot correctly first time. The result was that things looked normal on the monitor until I ran DCS and it was then obvious it wasn't using the GPU. Checking the devices showed that the GPU wasn't driving the graphics as the motherboard couldn't see it. Link to comment Share on other sites More sharing options...
CraigFoulkes Posted April 10, 2020 Author Share Posted April 10, 2020 Its definitely picking my RTX2080TI up as my onboard graphics are not capable of vr. Sn my oculus in plugged in to my GPU, I will however check and make sure its seated tomorrow but fans are running freely. Link to comment Share on other sites More sharing options...
CraigFoulkes Posted April 12, 2020 Author Share Posted April 12, 2020 So checked all the above card is seated as it should be however the problem is still there, Also had an Email from Oculus today to say they still cant find any problems with my log files but are still looking in to the matter. I can ( RMA ) my gpu and I should have a replacement back 48hrs after they receive my gpu. But I have also ordered a new VR head set Link to comment Share on other sites More sharing options...

But I have also ordered a new VR head set I don't think it is your headset, sounds like the GPU based on what all you have described. But who knows, these are computers and they can do about anything.

=Panther= Posted April 12, 2020 Share Posted April 12, 2020 The safest and cheapest solution is to up the PSU like Aurelius mentioned. 550 is rather low for the demand the 2080ti card draws, especially in VR.

CraigFoulkes Posted April 13, 2020 Author Share Posted April 13, 2020 Regarding the PSU as I have been scratching my head for over a week now with this issue, i did check specs of the card and i noticed my PSU was 100w lower that what nvidia recommends a min ( 650w ) I mentioned this to Scan who told me they are aware of this and are offering a free upgrade of a PSU to 650w. However I'm thinking of paying some extra and getting an 850w to give me plenty of breathing space and be future proof so to speak. The one thing I cant figure out though is this only started after Oculus update. Maybe just a coincidence ? Link to comment Share on other sites More sharing options...
CraigFoulkes Posted April 13, 2020 Author Share Posted April 13, 2020 Had a nice surprise this morning, notification on Amazon that my VR will be arriving today and not ( Thursday ) bonus or so I thought. All installed and what do you know..... The problem is still there! Could cry right now ( give me strength) Link to comment Share on other sites More sharing options...

All installed and what do you know..... The problem is still there! Could cry right now ( give me strength) You previously mentioned you tried your Rift on a friend's PC and it was fine with it. I would think that showed that it was not the headset. I think it is likely either the GPU or Power Supply.

CraigFoulkes Posted April 15, 2020 Author Share Posted April 15, 2020 Yes I agree that did show that the problem wasnt with Rift to be fair, however I did want a better quality VR, The GPU was sent back yesterday 14th so they should have it by now. I'm hoping to have a gpu back by Friday. So we should know for sure. Either way I'll be sure to pop back and post my findings Link to comment Share on other sites More sharing options...
CraigFoulkes Posted April 16, 2020 Author Share Posted April 16, 2020 Just thought I'd give a quick update. My card was received and tested yesterday from Scan computers my RTX2080TI was found be be faulty. As of yet I dont know the actual fault but I will do my best to find out. Although my PSU is 550w and Nvidia recommends a min 650w for this card it's not seen as a factor in this issue. 2012532281800xxx SN of my card last 3 replaced with " xxx " This fault however only occurs when using VR Link to comment Share on other sites More sharing options...
Greyman Posted April 16, 2020 Share Posted April 16, 2020 (edited) Have you checked that the on-board graphics have been disabled in BIOS. Even if no displays are plugged in to the on-board graphics, it might still be worth turning them off. Edit: ah, that'll teach me to read the second page of the thread, that i hadn't noticed before i posted, but i'll leave this here, as it might still be useful, even with the new card.

CraigFoulkes Posted April 17, 2020 Author Share Posted April 17, 2020 So although this post is labelled ( Oculus Rift VR Issue ) I'd like to point out I had the same issue when trying my Reverb VR, So my replacement card arrived today. I was told this card was tested however all security seals still in place. Anyway new card fitted and the exact problem is still there, chances of having a 2and faulty card ?

CraigFoulkes Posted April 18, 2020 Author Share Posted April 18, 2020 That's the only thing I can think of now to be fair, I'll call them in the morning see what can be sorted out. Thanks for all your help and Advice it has been much appreciated. Link to comment Share on other sites More sharing options...
CraigFoulkes Posted April 18, 2020 Author Share Posted April 18, 2020 So after continuing to have these issues even after receiving my new RTX2080TI I was asked by the Tech guys at Scan to wipe all partitions and do a fresh install of everything to see if it help.............. And no joy, I also have a HX 750W psu so I thought worth a try. Didnt make a difference at all. Scan computers told me I had two options, RMA the card for a second time or RTB my full system. So the full system is going back Monday clearly this issue is much bigger than I originally thought. Link to comment Share on other sites More sharing options...
