You are using 2 loops that do the same thing. Use this:

pawn Код:

#define DIALOG_FPS_LIST (1337)

new
    FPSList[512];

for(new i = 0; i < MAX_PLAYERS; ++i)
{
    if(IsPlayerConnected(i) && !IsPlayerNPC(i))
    {
        format(FPSList, sizeof(FPSList), "%s%s:    %s\n", FPSList, pName(i), GetPlayerFPS(i));
    }
}
ShowPlayerDialog(playerid, DIALOG_FPS_LIST, DIALOG_STYLE_MSGBOX, "Players' FPS", FPSList, "Ok", "");

You will also need:

pawn Код:

stock pName(playerid)
{
    new
        iName[MAX_PLAYER_NAME];

    GetPlayerName(playerid, iName, sizeof(iName));
    return iName;
}
