Switching from 1.60 to 1.61 causes a huge performance drop to a few frames a second. Happens in simple scenes with spot lights and Clustered Lighting enabled.
Directional Lights and disabled Clustered Lighting works fine.
Happens on Win11, Firefox and Chrome.
Also iOS/Safari seems to be affected
I can confirm the same, here is a scene with all shadows disabled, just 1 directional light and a big number of point lights (50). The performance hit is massive indeed in 1.61:
Hi @TRT - I cannot reproduce a performance issue on your project - I tested in chrome on windows 10 and safari (apple chip) and that runs very fast.
Are your graphics drivers up to date?
How about this example? Is it slow for you? PlayCanvas Examples
The performance hit may not seem massive (~2ms higher), but if you have multiple materials in view affected by a clustered light (lots of pixels) then it becomes massive indeed.
