In your screenshot, the max render time is set to 10s, that's probably why your GPU goes back to 0, but you got 114 iterations in 10s, so the GPU is definitely used. For the larger scene it's hard to say without seeing a log file.
Hi ! I create a new PC. msi z390 a pro gigabyte GTX 1660 super 16 GB ram. I5 9400F In substance Painter i have active the buttons IRAY HARDWARE: CPU and GPU. But when i go in rendering mode iray (f8) if i see the ACTIVITY in windows 10, RAM and CPU go high 70-80 % but GPU is at 0% . remains at 0% any work I do in substance…
RAM go up to 90% the speed of render si very very slow for 350 samples Slow to open the scene. In viewport i can work fine, but the rendere is absolutely slow, and i can't change the view in render mode because is very LAG. The scene is a city DIORAMA many TEXTURE SET (but not too big, 10 or 12 2k texture the other 512…
I see the solution. going forward with the render I noticed that the iterations went too fast, you were right.I asked myself.....What if the data I see on monitor is not real?I used another TOOL (CPUID) for monitoring the GPU.The load is FULL! memory, buffer is all full so the GPU work. Is the WIN 10 tool that doesn't show…
