@Rosamaha r_mode is for window resolution and r_imageQuality is for the render's resolution, r_resolution is not even a valid dvar with any COD engine build.

Make sure he forwards 27016 to 27020, which is a good safe range to use. When trying to connect try using any of those ports within that range to connect. And make sure you're using their correct external IPV4 address, which can be obtained by your friend by them Googling "What is my IP".

If you want to achieve this in a private match just enable sv_cheats and set cg_drawFPS to 4 and you can use the command setviewpos to teleport you to your desired coordinates.

@Rosamaha That is a COD4 singleplayer mod, nothing like that is possible multiplayer.

Did you make sure your volume is turned up...? Did you check your audio settings in the main menu...?

@sabri123 "Open command prompt in the folder that you have the Plutonium Launcher" You did NOT do that part, you need to CD (https://www.digitalcitizen.life/command-prompt-how-use-basic-commands) into your launcher's directory then run that command.

Navigate to %localappdata% on your PC and go to the Plutonium folder and delete info.json.

Change your resolution in the game's settings to match that of your monitor's maximum resolution and the screenquality (also in the settings) to native.
