everest101 Posted February 3, 2023 Posted February 3, 2023 (edited) I have been testing my VR configuration/stability & visual improvements with my Pimax5k Super HMD since DCS provided OpenXR support. At first, tests where KO and could hardly just get to the flight phase. But a recent break through has occurred and has changed the testing results by 180 degrees for the better. The big game changer happened yesterday when I found out that the OpenXR Toolkit was revised to v1.2.4. to improve usability with DCS OpenXR implementation, see note 1. I will spare you the testing details and jump directly to some results/configurations that work for me. Hardware configuration: (if you wish to compare, here are my PC details) Mobo: MSI X570-A PRO/PCIe 4 CPU: AMD RYZEN 9 3900X (12 CORE) GPU: EVGA-RTX 3080Ti RAM: DDR4-32 GB (3200MHZ wt XMP) HMD: PIMAX-5K SUPER Software configuration: DCS World Open Beta v 2.8.2.35759 (latest as of 3 FEB 2023 & wt OpenXR support) PiTool v1.0.1.284v - Version 284 is required as per PimaxXR requirements. See note 1. PimaxXR v0.3.0 - This app is the runtime required for OpenXR to work with PiTool and to bypass SteamVR. PimaxXR runtime is needed to avoid PiTool kick starting SteamVR by default. Install PimaxXR and make sure that PimaxXR is selected as the OpenXR runtime. See note 2. OpenXR Toolkit v1.2.4 – Latest version as of 2 FEB 2023. See note 3. OpenXR Explorer v1.4 - Optional application to analyze OpenXR runtimes & OpenXR Toolkit app that is installed. Not required for success in implementing OpenXR with DCS. See note 4. OpenComposite - This application and its DLL implementation into DCS is not required for success in implementing OpenXR with DCS. However, you may need it for other VR games or simulators that are designed to use the SteamVR app to run them in VR. See note 6. Recommendations: Always make sure that the PiTool app is UP and running regardless of what VR runtime (SteamVR or OpenXR) you use. Otherwise, your Pimax HMD is not available for your VR sessions. If you have configured a DCS game start icon in PiTool and wish to test OpenXR runtime, avoid using that game start icon. Starting DCS from the PiTool/My games/DCS icon will kick start SteamVR. Having DCS started via SteamVR while OpenXR is configure for the game will likely cause undesired results. If you are going to run or test DCS OpenXR VR method (bypassing SteamVR), for safety, just delete the game start icon in PiTool as you will not really need it anymore. Instead, do the following… Exploit the DCS command line features to start the simulator as these will be useful to you. Make yourself some DCS game start window shortcuts to facilitate things. Here are some windows shortcut command line targets that I use. Make a DCS game start shortcut for each of the following shortcut targets & see note 5 for other DCS post link; "your game install path\DCS World OpenBeta\bin\DCS.exe" --force_enable_VR --force_OpenXR - to start DCS with OpenXR support. Make sure that SteamVR is not running. Make sure that OpenXR Toolkit is enabled. At first, use the default Toolkit shortcuts. Also, make sure that active OpenXR runtime is ticked back to OpenXR within the PimaxXR app. This will enable bypassing SteamVR and will avoid SteamVR from being called. "your game install path\DCS World OpenBeta\bin\DCS.exe" --force_enable_VR --force_SteamVR - to start DCS with SteamVR support. If you revert back to using SteamVR, make sure that the OpenXR Toolkit is disabled (tick the disable switch in OpenXR Toolkit) and that active OpenXR runtime is ticked back to STEAMVR within the PimaxXR app (start PimaxXR app and select SteamVR as the runtime). "your game install path\DCS World OpenBeta\bin\DCS.exe" --force_disable_VR – to start DCS without VR so that DCS displays on your primary display screen. This could useful for HOTAS configuration, etc. Without guaranties, this methodology should work for Pimax4k, 5k or 8k HMD owners. Can all these pieces of software & apps co-exist at the same time on your PC. YES, however, configuring the apps correctly is required if you wish to use DCS with SteamVR or with OpenXR. See comments above depending on the shortcut command lines that you are using to start the DCS simulator. You need to experiment with the OpenXR Toolkit settings. Do that using the Toolkit shortcuts while in the game. Settings will likely vary if you have a Pimax4k, 5k or 8k HMD. When your satisfied with your Toolkit settings, share them with the community by writing your own post. Using OpenXR... Generally speaking, I am getting better control of my FPS frame rates, better control of color effects and better control of sharpness inside the cockpits. I do experience a bit of stuttering when switching from F1 to F10 and back to F1 views...not sure what would cause that. So far, multiplayer seems OK. Could the experience be better...YES. Correcting the stuttering when changing views needs to be addressed but I am not sure to who I should shot the requests ...to DCS regarding their OpenXR implementation, to the PimaxXR folks dev team or to OpenXR Toolkit dev team...don't know! Hope this helps you enjoy OpenXR with your Pimax HMD. Everest…Out! Notes: 1- For PiTool v1.0.1.284v, see https://community.openmr.com/t/pitool-1-0-1-284v/39823 2- For PimaxXR v0.3.0, see https://github.com/mbucchia/Pimax-OpenXR 3- For OpenXR Toolkit v1.2.4., see https://mbucchia.github.io/OpenXR-Toolkit/ 4- For OpenXR Explorer v1.4, see https://github.com/maluoi/openxr-explorer/releases/tag/v1.4 Be aware that this app is not required for OpenXR implementation with DCS. It is included here as reference only and is recommended for folks that do application development work. 5- For DCS news letter regarding OpenXR implementation, see the following forum post: https://forum.dcs.world/topic/318004-dcs-now-supports-openxr-natively/ 6- For OpenComposite & OpenComposite switcher, see https://mbucchia.github.io/OpenXR-Toolkit/opencomposite.html Note that no revision is mentioned for OpenComposite probably because this is actually a DLL which did the work of throwing DCS VR runtimes to PimaxXR before introduction/support of OpenXR in DCS. OpenComposite solution is no longer required to operate OpenXR in DCS. PS...If you like this post, please rate (@ top of post) or like it... Edited February 5, 2023 by everest101 Added PS reminder.

mbucchia Posted March 2, 2023 Posted March 2, 2023 There is a 0.3.2 official version now: https://github.com/mbucchia/Pimax-OpenXR/wiki#installing It's essentially 0.3.1 plus a few more fixes (not particularly meaningful to DCS though). 1 I wasn't banned, but this account is mostly inactive and not monitored.
chev255 Posted March 6, 2023 Posted March 6, 2023 Hi everyone, first thanks a lot mbucchia for PimaxXR and Everest for this topic! I am coming back to DCS and VR after a few years and I am not able to get my 5K plus to work... I have Pitools version 284, OpenXR toolkit 1.2.4, Pimaxxr 0.3.2 and OpenXR Explorer 1.0.25. I have added "--force_enable_VR --force_OpenXR" to my DCS shortcut. When I start DCS, it goes to the normal menu (not VR) although the screen aspect ratio is matching the Pimax. Nothing can be seen in the Pimax other than the "Pimax home" landscape. When I look at logs I find an "XrResult failure [XR_ERROR_RUNTIME_FAILURE]".

Ajax_ Posted March 8, 2023 Posted March 8, 2023 I feel ya @Chev255 - One month later, I figured I would see if I would have better luck. I tried following all the instructions again. Updated to DCS OB v 2.8.2.35759 again Using PiTool v1.0.1.284 PimaxXR v0.3.0 (used v0.3.1 & v0.3.2 to no avail as well) OpenXR Toolkit v1.2.4 Applied the DCS.exe parameters --force_enable_VR --force_OpenXR to my shortcut Everything works, but the micro stutters were just unbearable and made me sick. -------- Thought I would try to just run the previous way with OpenComposite, so I removed the parameters from the DCS shortcut (replaced the openvr_api.dll in bin) and DCS works fine until mid way through a mission. I accessed F10 and: I had these same issues the first time I updated and did troubleshooting in early February so I am reverting back to DCS OB v 2.8.1.34667.2 again. (Nothing worse than being 1/2 or even almost finished with the mission and having DCS crash.) But, the reason I am posting is because I want other Pimax users to know that there are other Pimax users that have spent many, many hours trying to get this to work with no success and have rolled back. I know we all really hope the next update corrects the issues. It will be great to make a step-by-step thread for Pimax users to help sort 3rd party software issues too. Thanks @everest101, we all appreciate the time and effort in your post. I also think it is worth noting to @mbucchia that I did notice more stuttering with PimaxXR v0.3.1 & v0.3.2 (just in case you had not heard that from anyone). And my hat tip to your work on helping try to sort these issues too. We are a strong community, even if it seems like most just lurk. The resources here are amazing, and it is a bit overwhelming to speak up with so much information and posts already existing for most topics. However, that being said, I am available to discuss my findings in detail if anyone cares, and until the next update, I'll just keep searching the threads to see if anyone else uncovers something I have missed or that works around the stuttering or crash issues. Ajax out.
Ajax_ Posted March 9, 2023 Posted March 9, 2023 In follow up to my prior post. @mbucchia I think I have a clue, hint or something that may be involved with the micro stuttering issue I experienced in v2.8.2.35759. Now that I have reverted back to Open Beta v2.8.1.34667.2 I continued to use PimaxXR v0.3.0 but got an Open Composite crash when accessing F10 in a mission. (If you recall, I mentioned in my previous post that PimaxXR v0.3.1 an v0.3.2 seemed to introduce micro stuttering in Open beta v2.8.2.35759) So I uninstalled PimaxXR v0.3.0 and then installed PimaxXR v0.2.8. Now I am able to complete missions and access F10 Map without any issues in the rolled back version 2.8.1.34667.2 *I remember reading earlier last month that there were some event/timing type inconsistencies with the OpenXR implementation, so again, I wonder if the next update will sort this out for Pimax headsets. Just scratching my head... Cheers, Ajax out.

(If you recall, I mentioned in my previous post that PimaxXR v0.3.1 an v0.3.2 seemed to introduce micro stuttering in Open beta v2.8.2.35759) So I uninstalled PimaxXR v0.3.0 and then installed PimaxXR v0.2.8. Now I am able to complete missions and access F10 Map without any issues in the rolled back version 2.8.1.34667.2 *I remember reading earlier last month that there were some event/timing type inconsistencies with the OpenXR implementation, so again, I wonder if the next update will sort this out for Pimax headsets. Just scratching my head... Cheers, Ajax out. Are U still having your micro stuttering problems with DCS OB o your PC? If yes, please provide a summary of what is in your PC, ie. Mobo,CPU,GPU,RAM, HMD device. etc... You could be limited by your PC...it's possible! Just to say, from my end, my PC si working super well with Pimax-5k super in DCS OB using OpenXR and in single thread (ST) mode. My setup has changed slightly on the software side (nothing big though). Simply consult my short summary of latest software versions needed in my reply to @chev255 for good results with latest version of DCS OB. And also, just to say, when it comes to DCS OB + OpenXR + multi-thread (MT) mode, the game is KO on my side. ED really needs to fix MT mode...or is it PimaxXR which needs to be fixed? Don't know for sure!!! But MT is not the subject of this conversation...soo lets leave this issue out of this conversation. Edited April 9, 2023 by everest101 MOBO/MSI X570-A PRO/PCIe 4.

chev255 Posted April 15, 2023 Posted April 15, 2023 Sorry Everest I should have updated the topic, I reinstalled windows and that fixed the issue somehow! Thanks for your help
