Processor ratio problem

Hello everyone. I’ve been working on a game for a long time, but there’s a problem: the engine only uses 40% of the processor. Therefore, I’m having difficulty programming the enemy AI, and the game’s movement is very poor. Please reply, and thank you.

Only? That’s fine, lower processing usage is better and is generally lower in DX12 and Vulkan as that’s’ one of the things it does. The CPU isn’t supposed to have high usage especially now days modern Graphics APIs, if so then you CPU becomes a bottleneck. Also more things have been moved to the GPU to take the strain off the CPU as it slower at doing certain operations.
