    Settings for cs 1.6 steam and ADSL

    How to set settings with tcpotimizer and drtcp for cs 1.6 for better player skill?
    I have internet ADSL 10/0,768 Mbps.
    Code:
    TCP options string = 020405ac0103030801010402
    MTU = 1492
    MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
    MSS = 1452
    MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.
    Default TCP Receive Window (RWIN) = 66560 
    RWIN Scaling (RFC1323) = 8 bits (scale factor: 2^8=256) 
    Unscaled TCP Receive Window = 260 
    
    In Windows 7, unless "TCP/IP Auto-Tuning" is disabled, only the Current TCP Window is displayed. Use the latest TCP Optimizer for tweaking.
    You seem to be using Google Chrome. Note that Chrome can modify the TCP Window for sockets it creates under some OSes, and therefore servers may not get your OS-assigned RWIN value. FAQ
    RWIN is not fully optimized. The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65536 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.
    
    RWIN is not multiple of MSS. If your OS supports setting RWIN directly, consider changing it to a multiple of MSS for optimum performance.
    Other RWIN values that might work well with your current MTU/MSS: 
    63888  (up to 2 Mbit lines, depending on latency. MSS * 44) 
    127776 (1-5 Mbit lines, depending on latency. MSS * 44 * 2) 
    255552 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2) 
    511104 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3) 
    1022208 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4) 
    bandwidth * delay product (Note this is not a speed test):
    
    Your current TCP Window limits you to: 2662 kbps (333 KBytes/s) @ 200ms latency
    Your current TCP Window limits you to: 1065 kbps (133 KBytes/s) @ 500ms latency
    MTU Discovery (RFC1191) = ON
    Time to live left = 45 hops
    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000 (0)
    Code:
     SpeedGuide.net TCP Analyzer Results  
    Tested on: 2017.11.14 13:36 
    IP address: 31.223.xxx.xxx 
    Client OS/browser: Windows 7 (Chrome 62.0.3202.89) 
     
    TCP options string: 020405ac0103030801010402 
    MSS: 1452 
    MTU: 1492 
    TCP Window: 66560 (not multiple of MSS) 
    RWIN Scaling: 8 bits (2^8=256) 
    Unscaled RWIN : 260 
    Recommended RWINs: 63888, 127776, 255552, 511104, 1022208 
    BDP limit (200ms): 2662kbps (333KBytes/s)
    BDP limit (500ms): 1065kbps (133KBytes/s) 
    MTU Discovery: ON 
    TTL: 45 
    Timestamps: OFF 
    SACKs: ON 
    IP ToS: 00000000 (0)

    I'd start with the "optimal" TCP Optimizer settings with your current MTU, then look through the gaming tweaks article here:
