A lower frame rate gives breathing room and helps in memory optimization. I personally find a 0.03 fixed timestep with a maximum of about 0.05 to be good for better performance. We can reduce the time spent on Physics updates by adjusting the fixed timestep setting. Increasing the timestep will reduce the CPU overhead but sometimes, the accuracy of Physics gets affected. - Timur Ahmetovhas quoted8 years agoPerformance optimization depends upon how fast we can render by GPU, which is mostly limited by the number of pixels rendered and by the memory bandwidth. The CPU performance is also limited by the amount of draw calls processed. We can use GPU Profiler to find out how much time and how many draw calls are in the scene. To save rendering time, we should remove as many draw calls as possible.
As shown in the following screenshot, by clicking on Stats, we can see the Statistics window: - Timur Ahmetovhas quoted8 years agoPrecalculation during development can be very important to achieve high performance and make certain effects possible. Taking the approach of calculating as much as possible at the start of execution can have a great impact on performance.
Apart from Physics-based performance optimizations, there are other factors too that we should use to optimize our game or app. Let's have a few examples.
