GPU Usage: WHY YOU NO STAY STEADY?!

post #1 of 54
Thread Starter 


So I was playing APB and noticed my GPU usage spiking constantly, but still staying in the higher usage percentages.

Anyone know why this is happening? I'm getting some "stutter" issues quite frequently where the game would pause for less than half a second, then continue. But it happens a lot. Not every 10 seconds but maybe a few times a minute.

I have a few background programs going but nothing that would cause a GPU spike, just messengers. Also have 8gb of RAM so it wouldn't be because of ram usage.

The GPU isn't used the same amount while you're playing any game. It will always fluctuate.

Sounds like a problem with the game or video drivers more than with the card itself.

Well typically, when both the CPU + GPU usage is high, with GPU dipping back and forth, its usually equates to a CPU bottleneck, either by no available cores or CPU speed. Sometimes its not just not having enough speed, but not having enough cores. It looks like all cores were maxed out, leaving nothing for anything else.

What is this game? Bad Company 2?

Whats the CPU speed?

Does the game your playing reflect this "jumpiness"? If not, it's probably just not using it's max potential because the game simply doesn't need it.

The CPU is never hitting 100%, while the GPU is. If anything is a bottleneck, it's the GPU, but only by a very small amount.

Occasional stutters can be caused by any number of things. If they happen at random times during otherwise high FPS, I don't see how it could be a bottleneck causing it.
