Graphics card sets the pace

The graphics card sets the frame rate at 1440p, with the processor keeping up comfortably. That’s how a gaming PC should be — you’re getting everything you paid for from the card.

What a bottleneck means

Every PC is limited by something. The processor sets a ceiling on how many frames it can prepare each second, and the graphics card sets a ceiling on how many it can draw. Whichever is lower decides your frame rate. A gap under 10% is nothing to worry about.

The graphics card setting the pace is normal and healthy, especially at 1440p and 4K: you’re getting everything you paid for from the card. A big processor bottleneck at the resolution you play is the one worth fixing, because part of your graphics card sits idle.
