Why might my game have performance issues I don't know about?

Because your dev machine is fast and may be the only place you've tested, while players span a wide range of hardware where the same game runs very differently, and players rarely report performance problems, they just quietly churn. So performance issues can be widespread and invisible to you at the same time. Only capturing real-device performance data reveals whether your game actually runs well for players.

What should I look at to spot performance problems?

Frame-time spikes and worst-case frames (the 1% lows), not just average FPS, since average hides the hitches and stutters players actually feel. Capture this from real devices so you see the experience across the hardware players use, and correlate the spikes with what the game was doing to find causes. Players won't report these problems, so this measurement is the only way to find them before they drive churn.

How Do I Find Out If My Game Has Performance Issues?

Q: How do I find out if my game has performance issues?

Capture performance data from real players' devices (not just your dev machine, which hides issues that only appear on weaker hardware) and look at frame-time spikes and worst frames rather than average FPS, since those are what players feel as jank. And remember players rarely report performance problems, they just churn, so monitoring is the only reliable way to know if your game runs poorly for anyone but you.

Quick answer: Capture performance data from real players' devices and look at frame-time spikes and worst frames, not just average FPS. Players rarely report performance problems, they just churn.

You might think your game runs fine because it runs fine for you, while players on other hardware struggle. Performance problems are invisible without measurement because players rarely report them. Here's how to find out if your game actually has performance issues.

Don't Trust Your Own Machine

Your dev machine is one fast configuration; players span a wide range of hardware where your game may run very differently. Performance that's smooth for you can stutter on a player's mid-range phone or older PC. So 'it runs fine for me' is no evidence your game is free of performance issues.

Bugnet captures performance data from real player sessions tagged by device, so you see how your game runs across the hardware players actually use. Finding out if you have performance issues starts with measuring the field, not trusting your own machine.

Look at Frame-Time Spikes, Not Just Average FPS

Average FPS hides the problems players feel. A game averaging 60 FPS but spiking regularly feels worse than a steady 40. To find performance issues, look at frame-time variance and the worst frames, the spikes and hitches, because those are what players actually experience as jank.

Bugnet's performance snapshots capture frame-time data, so you can see the spikes and worst frames, not just a flattering average. Looking at variance is what surfaces the stutters and hitches an average would hide, the real performance issues that drive players away.

Remember Players Won't Tell You

Performance problems are uniquely invisible because players rarely report them, they'll report a crash, but 'it ran a bit poorly' usually just makes them quietly churn. So you can't wait for reports; if you're not measuring performance, you're effectively blind to it, no matter how many players it's affecting.

Bugnet's performance capture makes the invisible visible, showing the frame drops and slow loads players experienced but never mentioned. Finding out if your game has performance issues is not trusting your machine, looking at frame-time spikes, and remembering players won't tell you, so monitoring is the only way to know.

Don't trust your own machine, capture performance from real devices and look at frame-time spikes, not average FPS. Players rarely report performance issues, so monitoring is the only way to know.
