after set registry "HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ActiveRuntime" to None, it work's. Using the MT option in Steam.
But, the performance is very bad. FPS is around 35, 45, with config settings high. And the GPU frametime and CPU frametime is very high, always red. Very unstable. And using OpenXR and Virtual Desktop (not steam virtual desktop)
Using old VR option, the performance is better, reaching 45 fps, much more stable. But something is wrong, I'm using a RTX 4070Ti, 32gb memory (3600), running on ssd m.2, wifi 5g using PICO 4, Intel I5 9600k.
Some players are reporting FPS around 70, 80, with config setting high, using a RTX 3080.
I can't understand what's going on. I bought the rtx 4070 Ti and PICO 4 expecting some improvements using MT and expecting change from TrackIR5 to VR, but until now this is not going well.
But in 2d the MT was a game change. Overall. But for me, in VR, I'll expect the next update bring some improvements, fix this issues.
Thanks.
