This sounds right. At 1440p the GPU has to work hard as it's producing a lot of pixels per frame, so the usage goes up while the frame rate drops. This helps the CPU as the lower frame rate gives it a chance to keep up. On 900p, the GPU is producing frames faster than the CPU can keep up, so it has to wait, causing the usage to drop.

The solution is to turn the settings up, or get a better CPU.
