If your graphics driver is timing out (TDR), windows might force the renderer to restart, which causes this warning. You can increase the GPU timeout limit in the registry, though this is a more advanced fix. Is it Always Slower?
: The fact that the software automatically reduces this setting implies that the original setting was considered too high for the current hardware or scene complexity. This adjustment prevents the application from crashing or using too many resources.
Remember: rendering is a balance of speed, quality, and hardware constraints. This warning is just your software telling you it is striking that balance as best it can. If your graphics driver is timing out (TDR),
When you enable both CPU and GPU rendering (hybrid mode), the scheduler has to balance workloads. The per‑thread limit is applied to each device separately. A slower device (especially CPU threads) may cause the renderer to clamp the samples per thread across all devices to avoid synchronization issues.
To minimize the impact of the warning and optimize rendering performance: : The fact that the software automatically reduces
Complex procedural modifiers can rapidly bloat your geometry footprint at render time. Issue with slow animation render times - SketchUp Forum
Convert high-poly assets (such as 3D vegetation or detailed furniture) into V-Ray Proxies ( .vrmesh ). This optimizes data streaming between system RAM and GPU VRAM. 3. Adjust V-Ray Performance Parameters This warning is just your software telling you
The warning notes that rendering "might be slower." This sounds counterintuitive—shouldn't fewer samples be faster? In this context, "slower" refers to efficiency
