Is my CPU bottlenecking GPU?

columbusohio · November 19, 2018

Hi there, I have a e5-2670 paired with gtx 1080 and 32gb ddr3 ram and 128gb 850 pro ssd.

I only play overwatch on a 4k 60hz lg monitor. The FPS right now is hovering around 55-75 during the gameplay.

When I check task manager in the middle of the game, CPU is always at 15-30, and GPU is always at 90-97%.

In this case, am I doing perfectly fine? is my CPU bottlenecking my GPU? Does near 100% use of GPU and low use of CPU means that CPU is not doing its job?

What can I do to further improve my Overwatch experience (fps output) besides changing monitors?

The FPS is 55-75 at all ultra mode, absolutely everything maxed out to the maximum.

That means that the CPU is doing its job, if it wasn't doing its job then the GPU wouldn't be loaded at almost 100% of usage. The GPU should be pegged at 99% of usage all the time during gaming, GPU usage drops usually mean that there's a bottleneck somewhere or that the game isn't demanding-enough to max it out.

This CPU isn't a good gaming CPU though, due to individual cores being weak so keep that in mind. Should do reasonably well at 4K with a GTX 1080 though.
