This is something that I address specifically in the description and in the video. The most unoptimized effect is the static effect, which does cause a performance dip. This effect is designed to be a learning tool for showcasing how to achieve some of these effects without having to know shaders, as well as an effect that can be used sparsely with minimal downside.
Running tests right now show that with all effects, except static, enabled, I can achieve an FPS of 2600+. Turning on static drops this down to 200+. If you are hitting an FPS of 40, then I would suggest you take a look at the rest of your code.
Feel free to reach out if you would like a refund on your $3. The reason I charge so little for these is because I create videos that explain how to do everything for free, and in that video I address these issues explicitly. Thanks
