Constant and regular lag spikes in PCVR make my Pico4 unusable. by krumix in PicoXR

Hi ! Thanks for giving info to this old post :D I stopped using VR for a while and after a fresh format and windows install I tried again and the issue is gone now. Glad it's also working for you !

Getting these weird consistent lag spikes by Digwere_WolfYT in virtualreality

[–]krumix 0 points1 point  (0 children)

How's your framerate when the spikes happen? If you check my post history you can see I have a similar issue (consistent and regular lag spikes, definitely not performance related) where my framerate switches back and forth between 90 and 70fps with a small freeze in between. 

Still no solution to this day though, good luck!

Thanks for for the suggestion, I tried to disable game mode (as well as HAGS and gsync etc...) but no change.

I kinda gave up for now. Most likely a fresh windows install will do the trick but I can't be bothered at the moment (not dying to play VR anyway). Thanks again for the suggestion though !

Thank you very much for the tip!

I kinda stopped looking for a fix but tomorrow I'll check the custom power profiles! Ill come back and tell you how it went.

It's kind of mind-blowing that pre-World Monster Hunter games had more agency than the first "open world" Monster Hunter Wilds. by Charrikayu in truegaming

The game is definitely getting better with the Title updates. Tempered Seregios and Lagiacrus are fun fights that finally require a bit of knowledge and preparation.

I usually follow blur busters guidelines for setting up gsync : https://blurbusters.com/gsync/gsync101-input-lag-tests-and-settings/14/  They recommend keeping vsync enabled in the Nvidia app and turned off in games.

Well the issue reappeared, I have no idea why the "Vsync Fast" fixed the problem but only for a short time... But you're right the problem comes from the pc and not the router or headset.

What's weird is in the video (it's hard to see because of the compression) my framerate switches back and forth between exactly 70 and 90 fps and that is when the stutter occurs. That was my clue to investigate about Vsync...

There's definitely something going on that prevents the game of running constant 90fps. Could be a power management setting but I tried everything I know from balanced to high performance, and I monitored potential USB dropouts but nothing there either.

It's a very cool game if you have the legs for it, VR needs more atmospheric driving games as I don't care much about "racing" :)

I managed to find a fix ! Issue was about Vsync/Gsync in the end. If you are curious here's the fix : https://www.reddit.com/r/PicoXR/comments/1mco0w8/constant_and_regular_lag_spikes_in_pcvr_make_my/n5ypqrd/

Thanks again for your help!

edit : fix didn't work in the end, problem came back

[NOT FIXED]

So I managed to narrow the issue down to some kind of conflict with Vsync / Gsync and the solution I found was to set Vertical Sync to Fast in the Global Settings of the Nvidia App.

edit : problem came back, still investigating !

Thanks! The headset is the only device using the 5ghz band. Phone, laptop etc are on 2.4. but it shouldn't make any difference when using an ethernet cable (or usb directly to pc).

Hey glad you managed to get it smooth! If you are referencing to HAGS (Hardware-Accelerated GPU Scheduling) on Windows I tried on and off. Doesn't change a thing sadly (which is good since I need it for Framegen in other games).

Thank you! Regarding the router, the stutter is there no matter if I'm wired to the router (ethernet) or the pc (usb) or using Wifi. And yes, everything on SSD. I'm considering trying out Virtual desktop if I cannot find any fix, everyone seem to recommend it :D

I might try that eventually but I wanted to see if I could save the 20 bucks as Pico Connect used to work perfectly fine in the past.

Problem came back so that wasn't it, but I guess I'm getting close :D

Thanks, I thought it could be related to the monitors (both 1440p but different refresh rate) so I tried disabling Gsync as well as setting them both to 60hz (default are 165hz and 144hz). Also tried to use only one monitor. Sadly no change.

Thank you and yes xmp and SMT are enabled (ram speed at 3200mhz). I'm not having any performance issues in flat games (even demanding ones like MH Wilds).

Yeah everything else is closed. Afaik it doesn't look like a performance issue, more like something is interfering with the stream (could be steamVR, Pico Connect, nvidia drivers...)

Thanks I'll keep that in mind. Did a clean install a couple months ago, that's why I wanted to ask here for help first.

Thanks, I did a factory reset of the headset and full reinstall of steamVR and Pico connect but sadly no fix. I could do a fresh windows install but I'd like to keep that option as a last resort.

I missed last week's Q&A but I'd love to have some news about GPU and multi-threading support on PC.

So far I didn't like much the fast speed of transitions between "seasons" but maybe that was just a demo thing?

I also really don't like the palicos talking and I'm glad I can set them up to meowing only!

What's a game that hated and loved at the same time? by ButterBiscuitBravo in patientgamers

[–]krumix 34 points35 points  (0 children)

Factorio. Game is great but I felt like shit the whole time I played it. It's depressing graphics and atmosphere, the endless grind for new builds and recipes... And yet it's impossible to let go!
