Hello,

Thanks for this library, We've been doing quite some progress with my dice rolling.

However I am having extremely low framerate performance in laptops without dedicated GPUs and high resolution displays (i.e. 4k), so I was trying to cap the dpr like this:

          threeJs!.renderer!.setPixelRatio(1.0);
          threeJs!.renderer!.setSize(width, height, false);

but I can't seem to make the viewport extend to the full screen of the app, having this set the viewport to a small corner of the screen.

Any thoughts or ideas for sorting this out, and in general, improving framerate in potato devices?
