i have very recently been learning winsock and my first network game is a client/server tron game that works perfectly except it only updates about 5 times a second.... here is the code for my main loop (off the server but the client is almost exactly the same) do{ //change dir for you if(key[KEY_UP])dir=0; if(key[KEY_LEFT])dir=3; if(key[KEY_DOWN])dir=2; if(key[KEY_RIGHT])dir=1; if(key[KEY_ENTER] && bombing==0)bombing=1; if(!key[KEY_ENTER])bombing=0; //send results load_packet(buff,dir,bombing); error = send (s[1],(char *)buff,sizeof(buff),0); //error = send (s[1],(char *)&dir,sizeof(dir),0); //error = send (s[1],(char *)&bombing,sizeof(bombing),0); if ((error==0)||(error==SOCKET_ERROR)) { cout << "Error: Player 1 quit!\n"; WSACleanup (); return 0; } //change dir for other guy error = recv (s[1],( char *)buff,sizeof(buff),0); //error = recv (s[1],( char *)&dir2,sizeof(dir2),0); //error = recv (s[1],( char *)&bombing2,sizeof(bombing2),0); if ((error==0)||(error==SOCKET_ERROR)) { cout << "Error: Player 1 quit!\n"; WSACleanup (); return 0; } unload_packet(buff,dir2,bombing2); //move you if(dir==0&&y>0)y--; if(dir==3&&x>0)x--; if(dir==2&&y0)y2--; if(dir2==3&&x2>0)x2--; if(dir2==2&&y2<SCREEN_H-1)y2++; if(dir2==1&&x2<SCREEN_W-1)x2++; putpixel(screen,x,y,70); putpixel(screen,x2,y2,40); } something like that...... anyway......... when i run the server and client on one computer, the game runs at lightening speed (as it should be) but when i tested the game out on 2 computers (28.8 and cable) it ran really slow a 28.8 should get (at an abslute minimum ) 1000 bits per second and i am sending 32 bits per game loop (2 for the send and 2 for the recv) unless i am extreamly stupid (whitch i might be...) i should be able to update the status of the game AT LEAST 1000/32=31.25 times a second and yet i am only getting 5 WHAT IS WRONG WITH ME???????

Well, depending on what protocol you are using, the Winsock provider can buffer your send requests and send them as a larger packet.

5-10 updates a second is what many games utilize.

If you have to send tons of tiny packets, try bunching them together. I usually send data about 5 times a seconds and interpolate everything.

It seems that the most likely problem that is slowing down my program is winsock buffering my packets and sending them all at once. Is there any way I can force winsock to bypass the buffer and send the packet immediatly???

Its the nagle
When you create the socket, you can pass a flag that disables it.

You''ll probably want to switch to UDP eventually as well....

buf is 2 bytes long (not dynamic)

what is the flag u pass to disable winsock buffering?
