How do I improve my game's performance?

Measure on real devices first to find the actual bottleneck, then optimize that, and verify on real devices, rather than guessing or testing only on your fast machine. Performance problems are device-dependent: your fast dev machine runs the game smoothly while real, especially low-end, devices struggle, so the problems are invisible on your machine. To improve: measure performance on real devices (especially low-end ones, where problems concentrate), find the actual bottleneck (CPU-bound, GPU-bound, memory, I/O) by profiling on the devices that struggle, optimize that specific bottleneck, and re-measure on real devices to confirm it improved. This targets effort where it matters. Bugnet captures performance data with device context from the field, so you see the real performance on your players' devices and which struggle, directing your optimization to the actual bottleneck on real hardware, and you can verify per version that performance improved where it mattered, optimizing based on measurement rather than guesswork.

Why does my game run fine for me but slow for players?

Because your dev machine is far more powerful than most players' devices, so performance problems that bog down real, especially low-end, hardware do not appear on your fast machine. Your machine has more CPU, GPU, and memory than the average player device and far more than low-end ones, so a performance load your machine handles easily can overwhelm weaker hardware, producing low frame rates, stutters, and long loads you never see. The same code runs fine for you (powerful hardware) and slow for players (weaker hardware), the difference is the device. This is why measuring only on your machine hides the problems players experience. Bugnet captures performance data with device context from the field, so you see how the game actually performs on your players' real devices (including the low-end ones where it runs slow), revealing the problems your fast machine hides, so you can optimize for the devices that struggle and verify the improvement on them, closing the gap between your machine's experience and your players'.

Should I optimize performance before measuring?

No, measure first to find the actual bottleneck, then optimize that, optimizing without measuring (guessing at bottlenecks) wastes effort on non-problems while the real bottleneck remains. Optimizing based on guesses is a common mistake: you spend time on code that was not the problem while the real bottleneck stays, and you may add complexity for no benefit. The right approach is to measure (on real devices, especially low-end ones) and identify the actual bottleneck causing a real problem players experience, then optimize that specific thing and verify the improvement. This directs effort where it matters. Bugnet captures performance data with device context from the field, so you can see whether you actually have a performance problem and where (on which devices, in what form), so you optimize when and where there is a real, measured problem rather than guessing or optimizing prematurely, and verify the optimization helped where it mattered.

Ways to Improve Game Performance

Quick answer: Measure on real devices since your fast machine hides problems, find the actual bottleneck, optimize that, and verify on real devices, measure first, then optimize the real bottleneck, not guesses.

Performance problems are device-dependent and invisible on your fast machine. Here are the best ways to improve game performance.

Measure on Real Devices

Improve performance by first measuring on real devices (especially low-end ones), since your fast dev machine hides the problems players experience. Without measuring where the problem is real, you optimize blind.

Bugnet captures performance data with device context from the field, so you see how the game actually performs on your players' devices, revealing the real performance problems your fast machine hides.

Find the Actual Bottleneck

Improve performance by finding the actual bottleneck (CPU-bound, GPU-bound, memory, I/O) on the devices that struggle, via profiling, rather than guessing. Optimizing the wrong thing wastes effort while the real bottleneck remains.

Bugnet's captured performance data with device context shows where performance is bad and on which devices, directing your profiling and optimization to the real bottleneck rather than guesses.

Optimize the Bottleneck and Verify on Real Devices

Improve performance by optimizing the identified bottleneck (reducing the CPU/GPU/memory/I/O load causing it), then verifying the improvement on real devices, especially the ones that struggled. Confirm the fix where the problem was.

Bugnet tracks performance per version with device context, so after optimizing you can confirm performance improved on the affected devices, verifying the fix on the hardware that struggled, which your fast machine could not show.

Improve game performance by measuring on real devices (your fast machine hides problems), finding the actual bottleneck, optimizing that, and verifying on real devices. Measure first, then optimize the real bottleneck.
