If you want the best gaming performance out of your PC, the traditional wisdom is that you should chase 100% GPU utilization. There's some truth to that sentiment. If you're looking for the best performance possible, you want the limiting factor to be the component contributing most to your gaming performance, which, in most games, is your GPU. It's a good gut check against CPU bottlenecks and out-of-whack settings, but it's not the end goal.

Although you can use GPU utilization as a quick check to make sure your PC is operating smoothly, it doesn't say much about your performance, and it says even less about your real gameplay experience.

Why even use GPU utilization

It's an abstraction of what you're really looking for

First, it's worth looking at why GPU utilization is even important. The idea I've already laid out is the main reason. Your GPU is the most important component in your gaming PC, so anything short of 100% utilization means you're giving up some performance. That's true in a vacuum, but it needs some important context.

The main context: are you actually giving up performance? Although your GPU should, theoretically, be able to produce a higher frame rate if you're short of 100% utilization, that's not always true in practice. Maybe the game you're running doesn't scale past a certain point, giving you leftover GPU horsepower for handling other tasks. Or, maybe the game needs to scale higher on the CPU past a certain frame rate, which is certainly the case in games like Counter-Strike 2.

What GPU utilization is really good at highlighting is an extreme bottleneck. If you load up a game and see very high CPU utilization and very low GPU utilization, it's a clear sign that you have a CPU bottleneck. Don't misunderstand that concept, though. Your GPU is running at 80% utilization versus 100% utilization is not the same thing as it running at 40% utilization.

Once you start dealing with utilization north of 70%, you aren't really sussing out a CPU bottleneck. It's possible that lower than 100% utilization can expose a bottleneck somewhere in your system, but it doesn't guarantee it. GPU utilization, as a metric, is abstracted from both performance and the gameplay experience. It's a sign, but without an extreme disparity in utilization, you need other evidence to show that a bottleneck actually exists.

Power against stability

Peak performance isn't the goal in games

GPU utilization is a useful metric up to a certain point, but short of large gaps in utilization, you should probably ignore it. The more important thing to pay attention to is the subjective experience you get while playing games. That might mean sacrificing some of your peak performance, but when it comes to games, that's more important than squeezing out every last frame you can.

First, you should set a target frame rate for whatever game you're playing. If you can reach that frame rate and have a good experience, it really doesn't matter how the game is leveraging your components. In most games, that target is your monitor's refresh rate. If you have a 144Hz monitor, for example, you'll want most games running at least 100 fps. If you can't hit that mark, and you don't see a massive gap in utilization, you can set the boundary lower and use tools like DLSS Frame Generation or Lossless Scaling to make up the difference; i.e. a 60 fps target for a 120 fps output.

Once you can reach your target frame rate, set a cap there for the game you're playing. This will do two things. First, it ensures you aren't wasting GPU power. There are some games where an ultra-high frame rate beyond your monitor's capabilities can provide an edge — mainly titles where 500+ fps is possible, like Valorant and Rainbow Six Siege — but in most games, you're wasting power for no reason. Particularly at the highest end of utilization, you're encroaching on territory where your GPU is its least efficient, pushing excess power just to achieve that extra hair of performance.

The other thing it does is help your games run more consistently, at least as consistently as possible; we're all victims of unoptimized PC ports, after all. Without a frame cap, you're allowing your GPU to run as fast as it possibly can, and that's constantly changing. From second-to-second, scene-to-scene, your GPU will need different resources for rendering what you see on screen. You could jump from 180 fps down to 100 fps, back up to 170 fps, and then down to 110 fps all within a minute or two depending on the game you're playing.

These constant fluctuations are noticeable, particularly when you start seeing dips below 100 fps. You might be able to run one scene at 180 fps and another at 100 fps, and that's a gap you'll notice. If you have a cap set at 120 fps, however, you won't notice that dip to 100 fps nearly as much.

Make your GPU work smarter, not harder

Practical performance trumps the theortical

Chasing 100% GPU utilization at all times will, more often than not, lead to a worse experience than letting a pre-defined fps cap be the limiting factor. You're giving your GPU overhead to play with if it needs to, and it's not dissimilar from something like running your SSD below full capacity for the best performance. Really, though, you should throw out GPU utilization for everything short of a massive gap between it and your CPU usage. And even then, it doesn't really matter if you're still getting the gameplay experience you want.

If you want to drill down on your performance, there are much better metrics to use. I use Special K in just about every game I play, short of online titles — it can land you a ban — and it provides a ton of information. You can see your CPU and GPU frame times, active threads, and so much more. Metrics like that give you far more insight into your PC's performance than GPU utilization does.
