Slow viewer for large scene

[WangYixuan12]

I loaded habitat sim in the genesis and turned on the viewer. The FPS is pretty slow and viewer is not very interactive. The scene is shown as below. How could I speed up the viewer?

hey @WangYixuan12 noticed your viewer lagging with habitat scenes too, try flipping off the viewer (show_viewer=False) if you don’t need real-time feedback or just dial back the refresh_rate in viewer options.
also plenty of reports that big, static scenes tank FPS a bit, slike a viewer/renderer thing not yet optimised for heavy stuff
might just be easier to bypass the viewer or keep visuals light until things get tuned

Indeed it is not. A better renderer will come later. Our custom pyrender fork is only meant for debugging purpose and quick-and-dirty monitoring. We have gs-madrona for batch rendering, and LuisaRender for high-fidelity rendering, but nothing for large scene rendering at the moment.
