mrsylvestre Posted April 21 Posted April 21 The latest version of Pico Connect has a trick up its sleeve. It is now possible to stream OpenXR apps such as DCS World directly to the Pico headsets without going through SteamVR, a capability that was up to now exclusive to Virtual Desktop. This is clearly an experimental feature. The trick is to run the Pico-provided batch file add_runtime.bat located in one of the sub-folders of the Pico Connect application (see windows explorer screenshot, attached) with administrator privileges. It modifies the registry to install Pico Connect's own OpenXR runtime PicoStreamingXR instead of the default SteamVR OpenXR runtime (see SteamVR settings screenshot). It works well with DCS. Performance is quite close to that of Virtual Desktop at comparable resolution. Colors with Pico Connect are more vivid / saturated. It works through Wi-Fi but also directly through USB 3 connection without need of gnireteht or any other shenanigans. Credits for this find go to a user in the Virtualnull Desktop Discord. It is not clear at this stage if this runtime is an original effort by Pico or if they borrowed code from another project. Curious about how this will evolve. 2 5800X3D - 64GB DDR4 - Samsung 990 PRO SSD @ PCI 4.0 x 16 - 6950XT - Pico 4 (VDXR)

It's very sad that they are not giving attribution to the original code (which is technically a copyright infringement per MIT license of the original code). Edit: I should also add, it is based on a version of VDXR from 2023, so I'm not entirely sure they're even maintaining it? Otherwise why not tell people it is here? Why not pick a newer version that has more features and fixes? Edited April 21 by mbucchia I wasn't banned, but this account is mostly inactive and not monitored.

I was afraid it would be something like that. Sad indeed. 5800X3D - 64GB DDR4 - Samsung 990 PRO SSD @ PCI 4.0 x 16 - 6950XT - Pico 4 (VDXR)

My code is open source to allow that, but it would be really nice if companies using open source would take the time to follow the directions of the license 7 I wasn't banned, but this account is mostly inactive and not monitored.
VietGirl Posted April 25 Posted April 25 Hi can you provide if you have to still use Pico connect or Virtual Desktop after running the add_runtime.bat, would like to try this , thanks VietGirl
mrsylvestre Posted April 25 Author Posted April 25 (edited) This works exclusively with Pico Connect. Think of it as the Pico Connect equivalent of Virtual Desktop's VDXR. (Edit: PS. After trying that trick out of curiosity, I returned to VD (with built-in VDXR), which I happily use with a USB-Ethernet dongle and a dedicated (wired) router. I would consider connect as a contender if I didn't have the router and the dongle already) Edited April 25 by mrsylvestre 1 5800X3D - 64GB DDR4 - Samsung 990 PRO SSD @ PCI 4.0 x 16 - 6950XT - Pico 4 (VDXR)

Is Quad View working on Pico Connect for you? When activated, it seems the entire view is at the peripheral resolution, and the hi-res focus region isn't drawn
mrsylvestre Posted April 26 Author Posted April 26 Quadview is working in Pico Connect. Note that Pico Connect, like Virtual Desktop, has several presets for the resolution. "Super Definition" is about the same resolution as Virtual Desktop's "Ultra" if you want to compare apples to apples. There is also a sharpening slider somewhere in their settings. 5800X3D - 64GB DDR4 - Samsung 990 PRO SSD @ PCI 4.0 x 16 - 6950XT - Pico 4 (VDXR)
