The frame rate of large models is lower than before

The frame rate of large models is lower than before. The previous version had 60 frames per second, but now it only has a frame rate of 20-30 frames per second

Thanks for reporting this - looking into it!

May I ask when this issue can be resolved? The performance and frame rate are not as smooth as before when using large models

Hi wwjje, @vim-sroberge is currently working on a fix. Hoping to have it merged in the next few days.

Hi wwjje, The new release 0.39.0 includes performance improvements.
If you need maximum performance you can also consider using a material override like this

vim.scene.material = viewer.materials.simple

Hi，I tried it out，The frame rate has increased to around 40FPS, but still hasn't reached 60FPS. During use, there may be a slight lag and lack of smoothness when zooming in, out, or rotating. I tried another version (https://github.com/vimaec/vim-webgl-viewer/tree/v1.5.2) again, and no matter how I operate it, zoom in, zoom out, or rotate, it always has a full frame rate of 60FPS. Why is that?

I used the same computer and the same large model for testing. You can also test it. vim-webgl-viewer v1.5.2 performs very smoothly, always running at a full frame rate of 60FPS

I will look into it and try an older version. Thanks for the details.
