This image with 4M-polygon for plastic and specular (@ior 1.581 and @dispersion coefficient 0.008) pieces at our sun source on the glossy table@roughness of 0.5 with mix textures is rendered by my GeForce RTX 4090 using OctaneRender Standalone 2024.1.2:
This image is limited by 1280x800, at photon tracing with 1250 spp but lights reflected+refracted* have very low quality or are missed, and fixed caustics missed or almost invisibled on "dark gray" squares' table with "allow caustics" enabled are abnormal for check issues**.
-Rendered view-: -Screen, render and image settings-:
- Resolution screen: 7680x4800
- Render kernal: path tracing only because check issues**
- Number of samples per pixel: 3-million per region - total 2 regions picked
- Depthes ray: 36-diffuse and 41-specular
- Render time: 383h57min
- Format image: PNG 16-bit (exposure 4) and uncompressed EXR (exposure 1 for avoid any wrong color+brightness)
-> PRICE of 1 normal image rendered with free denoised included: US$35 for unlock all caustics and all lights reflected+refracted at full resolution screen.
-- This price is caused by my electricity cost and by my RTX 4090's lifespan.

-> You want to downscale any non-denoiser image to 2560x1600 (or to 1920x1200 or to 3840x2400) for reduce noises.

** - Wrong caustics with “allow caustics” enabled for Photon Tracing (PHT):
>- wrong caustics (less visible) on mix material with “allow caustics” checked like chess material
>- screenshot about caustics almost missed and caustics less visibled at PHT (top) but normal at PT (bottom):
Best regards.
