Problem: I will go straight to the fact. When I run dos games using dosbox the game starts to slow down...in some cases it stops. My pc is not freezing or hangsup. I need to "terminate" dosbox in order to regain control of dosbox 🤣.

The only exception to this is if I play doom 2 multiplayer. Also to note, if I play all those games in single player then ALL the games runs fine. This is the weird part.

Facts and info: I got an AMD quad core cpu with 4g of ram. I got a 1 terabyte HD with an audigy sound card. My bomb can run the latest games. So I don't think the hardware is not the problem. On the dosbox side, I can run redneck rampage and it's not stuttering, freezing, lagging ... no problem at all. I'm also using Windows 7 and my victim (test dummy, fresh meat, victim) has windows xp. We both got IPX installed... yup, my Windows 7 64bit got it too. and were using dosbox 0.74.

I started the ipx server on my side and he connected to me using my public IP address. Oddly enough, hamachi ip didn't work ???

When I play doom 2 with him on ipx then the game runs... a bit slow like the network bandwith was not enough but it's running. We tried Rise of the triad and that's where the game stopped working. The only image I could give you is if you tried to run doom 2 with 100 cycles in dosbox.conf...vveeeeerrrrryy slow.

What's going on ? Did I miss something ?

P.s: heres my dosbox.conf code...if that helps:
