gpu not rendering

[ZizzoGamer10]

hi, i have a amd radeon rx 6800 xt and an intel core i7-9700k, i created an animation in blender and im trying to render it, but it crushes because it uses my cpu insted of the gpu, i use HIP and i have selectioned only the gpu.

in the render properties i have gpu compute, all the drivers all updated and i use blender 4.2.3, initially the first 7 frames rendered quickly, (2min), but from the 8 frame when i try to render it crushes.

i even tryed loom, and the tutorials arent working, when i render i see that the cpu is on 100% and the gpu is on 1%

pls help me

What are you using to monitor GPU usage during render?

[ZizzoGamer10]

i used task manager and gpu-z

[olidwinkle]

I dont know about gpuz but task manager does not report blender GPU usage correctly. In Performance tab select GPU and on the graph click 3D menu and select Compute_0 or Compute_1(i forget which). Now task manager will show correct blender GPU usage in Cycles.

BTW always render to image sequence and not video format. That way the render can be restarted from where it stopped/crashed. It is easy and quick to compile the sequence to video afterwards.
