hello, i would like to know. why does the frameRate drop so much when I load about 100 pictures into the program. And how to fix it. Pictures from one color, with squares there is no such thing. 😐

Hi @urlxd,
One need to see your code to be able to analyse…

Hi @urlxd,
Please try this. Im not able to test as iam currently only have mobile access …

```auto
int size = 100;
int W = 20;
int H = 20;
PImage block;
Cell cell[][] = new Cell[W][H];
void setup (){
// use P2D renderer
fullScreen(P2D, 1);
// Useless
//block = createImage(size,size,RGB);
block = loadImage("block.png");
// If block not having size size do
block.resize(size,size);
for(int x = 0; x < W; x++){
for(int y = 0; y < H; y++){
cell[x][y] = new Cell(x,y);
}
}
}
void draw (){
background (0);
for(int x = 0; x < W; x++){
for(int y = 0; y < H; y++){
cell[x][y].make();
}
}
fill(255,0,0);
text(frameRate, 100,100);

Cell(int x, int y){
this.x = x;
this.y = y;

Hello,
I get 60 fps with your code with:
`fullScreen(P2D, 1);`

this can be calculated and stored in the constructor
```auto
x2= x * size;
y2= y * size;
```
and then the image line is just
```auto
image(block, x2, y2);
```

Thanks. I also only have a mobile phone because the PC is weak.

Hi @Chrisir,
This is a reasonable improvement, especially since the issue here is about performance…

However, based on the code above, I wouldn’t do it that way. Since in this case the size is not used for the class at all, I would do it directly at initialization…
`cell[x][y] = new Cell(x*size,y*size);`
and below just
`image(block, x, y);`
Cheers
