This is weird. I’m trying to use my 8KX after a lapse of a few months (long story). Anyway, Pimax sees the headset and base station, but SteamVR can’t find the headset and automatically blocks my Pimax. Note that the SteamVR icons show a headset and base station were found. When I re-enable the headset in SteamVR, SteamVR crashes again. At one point, I was able to enter the SteamVR Home app, but not a game. I turned SteamVR Home off and now I can’t turn Home back on.
I’m stuck in a loop and can’t play games. I am NOT using a SteamVR beta version. I’ve restarted the Pimax service and rebooted the headset multiple times.
I’ve also swapped USB ports and am now using my original Pimax cable (instead of the Pimax fiber optic cable). I’ve rolled back to my previously installed nVidia drivers.
SteamVR is still failing to find the headset. I can sometimes get into SteamVR Home, especially when I’ve just rebooted my system, but I can’t run any games. I had the problem last night; this morning, I downloaded and flashed the brand-new firmware for my 8KX, in the hopes that would fix this problem. No change in behavior, but I can actually run 90 Hz on my RTX 2080 non-Ti, which I wasn’t really expecting. I’ve uninstalled and re-installed SteamVR and now Steam thinks my VR Library is empty, even though my VR games are listed in the main game library.
To recap: PiTool seems fine, but SteamVR cannot find my headset and displays errors, even though I can run SteamVR Home.
@neal_white_iii I had similar issue like you, but I was not so lucky; I had to wipe my windows and to install everything from zero.
Everything else was not succesful (remove/add steamvr, pitool, steam and all leftovers from them), my steam was not working with steamvr (same critical error). Well I could play games from pitool directly, without even turning on steam, but that was inconvinient for some games (i.E. I couldn´t choose another vr controller configuration, or use “VR Neck safer” in fly simms).
I write this here in case more people have same issue.
I’m away from my VR setup atm but also having this problem. I’ll try to reinstall PT if that solves it, good to know thanks.
I found a strange workaround (eg when trying to get DCS to load in VR mode), which was to turn on a VR controller and load NMS (so mouse in PE causing an issue?). For some reason for me this is one of the few things that will not trigger a SteamVR crash. And after that stuff like DCS will load correctly in VR.
A new related quirk is with PE. Trying to click on any item (game or menu setting, doesn’t matter) will cause the whole UI to disappear for 10 seconds, leaving me just looking at the background skybox and nothing else. Wait for a bit and it comes back.
This happens repeatedly until I run the controller workaround. Mouse quirk? Not sure when it was introduced and whether the trigger was PT / firmware update (I’m on an older one) / Nvidia driver
Funny, I have used SVR with my 5K+ since it’s arrival without any issues in running it or any of my games so “complete mess” is not something I have experienced with it. On the contrary.
Happily playing VR on Steam since 2016
I have continued to have this problem (SteamVR keeps disabling my headset).
I found a solution which seems to have (finally) fixed it, once and for all. I uninstalled PiTool 220.127.116.111 and reinstalled 18.104.22.1680-20210322. Everything seems solid. Even better: I had set my 8KX to 90 Hz prior to uninstalling 271 and 90 Hz continues to work with the older PiTool.
@PimaxQuorra, please mention this issue to the developers. They need to find out (and fix) this extremely annoying issue. Thanks!
I have the exactly same issue recently . I had no problem with 22.214.171.1241 weeks ago but these days, it suddenly doesn’t work as described by Neal.
The latest SteamVR update? Windows update? Graphic driver update? I am not sure what caused this issue but it gives me a great concern about long term use of Pimax device as the headset is too sensitive to the new drivers or updates of SteamVR/Nvidia . Pitool developers need to find permanent solution to make the headset works regardless of minor updates by Steam VR or Nvidia driver.
BTW, Wasn’t new pitool supposed to be released last week or this week? I have seen the comment from Pimax forks from somewhere in this forum.
I had to temporarily except the whole \Pimax\Runtime\ folder to get 270 to install. But now that’s done, things seem to be working normally again.
I did a test with NMS, which I haven’t played for some time but thought I’d check the new Frontiers settlements update. Game loaded without any issues whatsoever.
As a bonus, using 90Hz + Motion Smoothing, I can now hold a steady 45FPS in the new town areas, and even better I can crank up a number of settings from Standard to High and it’s still running fine. So 90Hz mode + presumed game optimisations is a winner!
Also @neal_white_iii thank you very much for confirming that a rollback to 270 solved the problem. I probably would have just given up until a future fix otherwise
