Warning Num Samples Per Thread Reduced To 32768 Rendering Might Be Slower !exclusive!

"Warning: num samples per thread reduced to 32768, rendering might be slower"

Conclusion

: High values (above 3000) consume a lot of memory. Keeping them between 1000 and 3000 is generally ideal for 4K renders. Check High-Memory Features : Disable or simplify Displacement Subdivision "Warning: num samples per thread reduced to 32768,

: Close all other GPU-accelerating applications before starting the render. Optimize Geometry Displacement & Fur: These features generate massive amounts

: The engine has detected that there is not enough free memory to maintain optimal performance for the current scene complexity or resolution. Stability Over Speed // Use: rtcSetDeviceProperty(device

// Instead of:
rtcSetDeviceProperty(device, "max_samples_per_thread", 65536);
// Use:
rtcSetDeviceProperty(device, "max_samples_per_thread", 32768);

Displacement & Fur: These features generate massive amounts of geometry at render time.
