Is there a way to force the renderer to use more memory if it is available to improve interactive performance and decrease degradation? I’m noticing this with a NVIDIA graphics card and its using 1 of 4 dedicated GPU memory and doesnt touch the shared memory.
Similarly, is there a way to force the renderer to use less memory? If I tell my browser to use UHD Integrated graphics, the interactive performance is perfect but it maxes out my shared GPU memory of 16GB and if i add another render window it crashes.

The webGL code is already requesting the `high-performance` device, i think this is more managed by the browser/os rather than the user code.
