Two quick concerns/issues:

 

1. Using the 4d1 client, for some reason I have a few more lag spikes here and there and the lag is generally a little higher throughout servers than alterRev. I have noticed this is also the issue with others, will their be a fix for this, and if not, what kind of issue is it?

 

2. If you use the LaunchIW4M.exe to launch 4d1, how do you edit the xfire settings to get xfire to work? I tried making them both LaunchIW4M.exe and tried Launcherexe=LaunchIW4M.exe and detectexe=iw4m.exe. Both didn't work, any solutions?

2. This is right:

 

[5993]
LongName=Call of Duty: Modern Warfare 2 Multiplayer
ShortName=codmw2m
LauncherDirKey=HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam\InstallPath
LauncherExe=iw4m.exe
DetectExe=iw4m.exe
Launch=%UA_LAUNCHER_EXE_PATH% -applaunch 10190 %UA_LAUNCHER_EXTRA_ARGS% %UA_LAUNCHER_NETWORK_ARGS%
InGameRenderer=D3D9
InGameFlags=USE_PRESENT|USE_SWAPCHAIN|ENABLE_MOUSE|USE_DINPUT_MOUSE

Xfire: viewtopic.php?f=7&t=3830

LaunchIW4M launches iw4m.dat.
