When testing my VR-focused project using VR PiE, Ray Traced Shadows are disabled in VR and in the desktop spectator. Once the VR PiE session is over, Ray Traced Shadows are re-enabled in the editor.
Here is my config in the Rendering project settings: (press import in the Rendering project settings to apply them to your project) Rendering Backup 2023-01-06 001540.ini (5.0 KB)
And here is the Post Process Volume I use in my level: (copy and paste the text inside the file into your level and it will show up) Post Process Volume.ini (10.7 KB)
I’ve spent about a week trying to figure out a solution to this problem, but I’ve been unable to.
What kind of rig are you running to be able to play anything other than pong in VR with raytracing- two of the most computationally demanding processes a pc could be subjected to?
It does seem like a lot of people have had trouble with VR raytracing
I’m running a 3070 Ti with a 5800X. Because of the RT cores on my GPU, RT shadows is faster for me than VSM, so VSM is not ideal for me.
At the moment I get ~60fps during VR PiE with VSM. DLSS should get me up to ~90fps.
Lumen doesn’t provide an alternative to RT shadows (why it’s not deprecated, like the rest of the RT tech in Unreal). When using Lumen GI + reflections (you can’t use Lumen reflections without GI), I only get ~40fps, which is not enough for VR.
Additionally, baked GI + reflections are a much more attractive option for something like VR as they look just fine.
Also, according to Unreal’s docs, RT stuff should be supported in VR, which is why I still intend to use it.
Please keep in mind that not everyone has our level of hardware. Though, I don’t think this would run well even with a 3070Ti. If you ever want to release this game, you should probably at least add another option. Maybe check this out to get a feel for how many people could run this: Steam Hardware & Software Survey
Also, I’ve tried for quite a bit, but I can’t get raytracing even enabled, let alone working.
VR and AR are the only presets that don’t even have raytracing as an option, so saying it’s supported might be more of a technicality than endorsement.
