Q1：Besides startup speed issues, we're also facing performance challenges with UI particle effects. This problem doesn't only affect mini-games; mobile apps encounter it as well.
Our art team is currently using a dedicated UI particle management tool that performs particle simulation and refresh logic every frame. As the number of UI particles in a scene increases, the overall performance cost rises significantly. However, simply reducing particle effects often leads to concerns from the art team that the visual quality no longer meets expectations.
Is there a practical approach to balancing visual quality and performance?
A:To balance the visual impact of particle effects with device performance, simply removing effects is usually not the best solution. A lightweight optimization approach is generally more effective.
When creating UI particle effects, it's recommended to prioritize simple quad-based particles whenever possible and avoid mesh particles or particles based on complex models. This helps reduce rendering overhead at the source. At the same time, the overall particle count should be carefully controlled, and excessive nesting of particle sub-systems should be minimized.
For complex, high-cost effects, frame-by-frame animation sequences can sometimes be used as an alternative to achieve similar visual results with lower runtime computation costs. However, frame animations typically consume more memory and VRAM. When used extensively, they may cause stuttering or even crashes on lower-end devices, so the replacement strategy should be applied selectively and with proper scale control.
Q2：We've tried this approach before, but implementation is still challenging in practice. Once particle effects are simplified, the art team often feels that the visual quality drops noticeably. On the other hand, keeping all effects intact can easily lead to frame drops on some low- and mid-range devices.
For UI visual effects like these, how is the balance typically handled in real production projects?
A:That's a very common situation, especially in mini-game development.
Instead of using a one-size-fits-all approach and disabling effects across all devices, a more practical solution is device-tier adaptation.
High-end devices can retain the full particle effect setup. Mid-range devices can reduce particle counts, refresh frequency, and emission rates. Low-end devices can simplify or disable non-essential UI particle effects altogether.
By applying different configurations based on device performance tiers, teams can preserve as much of the intended visual design as possible while keeping overall performance costs under control. This approach helps achieve a better balance between visual quality and runtime smoothness across a wide range of devices.
