Did anyone notice if their viewport performance in the latest H20.5 is much slower compared to preview versions?
With 50M points in the viewport H20.5 struggle while on H20 or H19 it is just almost real-time when you pan and orbit on the very same hardware.
Are there any new settings I should tweek to gain back those performances?
PS: this is the default Houdini viewport, not Vulkan.

The performance is more or less the same with lights in the scene with gl in high quality lighting mode. Vulkan doesn't have 'normal lighting' mode so the pure headlight performance is about a 1/4 of what it was in gl.

Sounds like a headache. No 'normal lighting' is okay, but I'd expect at least headlight-only to be fast.

Did SideFx say anywhere what the performance characteristics of the Vulkan viewport are compared to the OpenGl viewport?
In the keynote they state that it's finished, but I was hoping for at least something like a 1.5x speed improvement?
In the release notes, they mention
But what does that mean for real world performance?
What are other people experiencing?

Threaded updates and rendering.

I didn't expect this one,
i thought Houdini viewport performance with realively heavy scene and texture or transparency to a weak admitted point of the package, with the previously announced Vulkan after 19.5 and now coming, i thought we coudl see some serious boost but certainly dropping half of the previous performance after this long wait.
What could we expect, what are advantage vulkan bring today on the table for us?
