GPU usage spikes when running a simple Unity game – normal behavior?

I’m testing a small Unity-based game project on my system and noticed that GPU usage sometimes spikes higher than expected, even though the scene is very simple and doesn’t have heavy textures or complex lighting.

I checked the drivers and they are up to date, and CPU usage seems normal. I’m wondering if this could be related to how Unity handles rendering on NVIDIA GPUs or if there might be a configuration setting I’m missing.

For testing purposes I tried running a small demo project from a site I found online that hosts simple game builds, and the behavior looked similar, which made me think it might be something related to GPU rendering or driver optimization.

Has anyone seen similar GPU usage spikes when running lightweight Unity projects? Any suggestions on what I should check (drivers, settings, or profiling tools) would really help.

Thanks in advance!

GPU utilization, memory utilization, graphics clock, and memory clock are all interconnected. Unless you believe that something else is wrong, it’s normal.

Not a Unity expert, so take this with a grain of salt, but: Was your framerate capped? A simple scene rendered at very high FPS can put a lot of load on the GPU.
The Unity forum is probably a better place to get a more precise answer.
