Is the viewport playback of USD files in Solaris expected to be considerably worse than usdview?

I have a flattened USD file that's about 500MB, with a legacy asset that has lots of transforms. When playing back the animation in Solaris vs. usdview, here is the difference:

usdview, default Storm view: 62FPS
Solaris (empty scene w. default desktop, sublayer in), default GL view: 2.7FPS

That's a 30X difference! And unusable for playback in Houdini.

Machine spec is Houdini 20.0.524 on Linux, AMD 3960x + NVIDIA 3090 w. 525 series drivers.

I am going to file this as a bug, but maybe it isn't and I just need to change a toggle somewhere?

Impossible to say without the USD file in question... Hopefully you were able to attach that file with the bug submission?

Out of curiosity, what is the playback rate in Houdini with the viewport set to render with Storm?

Thanks,
Mark

Mark,

Just filed here with a slightly smaller USD attached: https://www.sidefx.com/bugs/#/bug/133080 [www.sidefx.com]

Performance with Storm is better in an empty scene, up to about 10FPS. It's hard to test with Storm though as it's pretty unstable on my system.
