If you want to try it out, here is the first beta version of VR Sketch with a boosted rendering engine. This version only works with an Oculus headset tethered to a PC, typically a Quest—no SteamVR support, and also no standalone Quest for now. It will be fixed soon, of course.
This version sacrifices (some) quality for (a lot of) performance. It is several times faster than the existing modes. It is ideal if you have been struggling to have your huge models render at a reasonable speed. In that case, try again! The exact factor of speed improvement is unknown so far: no matter how large the models we try, they all render at the maximum frames-per-second on the headset… but according to our estimates, it might be 5 to 10 times faster.
It doesn’t display the textures or shadows, though both might possibly be re-added later. There are a number of bugs remaining to fix before it’s ready. And this doesn’t mean that the current, higher-quality images will go away: this new mode will likely replace the “performance” mode from the Settings dialog, but the default “quality” mode won’t change. (Performance improvements for the “quality” mode are still possible in the future.)
Our next step is to port this work to the standalone Quest, where a similar performance improvement is expected. Part of this improvement comes from a lower GPU memory usage—which is an interesting benefit particularly on Quest: the models can be more complex before running out of GPU memory. We still don’t expect to be able to load our most complicated models on the Quest, but we certainly expect a jump in the limit.
I will report our progress in this thread in the days or weeks ahead. For now, enjoy the beta for the tethered Quest!
