Drag A, B or C to change the triangle. I put the FPS at the top because I wanted to show how fast this worked compared to my other triangle filters. Down arrow to turn on/off rainbow. Up arrow to change the hex (color). Note: you can't change hex while in rainbow mode. I don't know why people have to make these so complicated.
I used a video on the internet. Use this for better performance: https://turbowarp.org/1155777123?hqpen
