Slenderzombie65 What's your antivirus? Also you have to play in windowed borderless, not fullscreen. Because of how old the engine is it tends to crash when playing in fullscreen

Go to %localappdata%\Plutonium\storage\t4\players and open the config file with the notepad to edit it. Make sure your game is closed before saving!
(plutonium.cfg is for singleplayer/zombies, plutonium_mp.cfg is for multiplayer)
Change these 4 values like this (you can use ctrl+f to search for it):

seta r_fullscreen "0"
seta r_noborder "1"
seta vid_xpos "0"
seta vid_ypos "0"

You can also change your resolution manually from there for example for 1920x1080 screens:

seta r_mode "1920x1080"

This will make your game use the windowed borderless mode which is highly recommended to avoid crashes caused by the engine.

natobear BO1 and CO4 already have clients so I doubt Plutonium will work on it, having 2 clients for a game is a bad idea. Duplicate things and split player base that already isn't that large (especially on games this old)

Samzzzzzzzzzz you're using cracked files that aren't supported by Plutonium. Read the install guide and follow the instructions. We won't help with files other than Steam or provided torrent

Luis142XD send a screenshot of the error don't copy it. Also reinstalling is useless as it's an issue on your end, not with Plutonium itself

savxt try switching to fullscreen mode (not borderless windowed). Also could be that your Nvidia settings override your in-game settings so your vsync might still be on, check in Nvidia panel (or AMD)

zudokai98 as always sending a screenshot of the complete error is better than writing half of the errror yourself

For future reference I highly recommend using PCGamingWiki whenever you wanna know something technical about a game they have a lot of information.

ReyCuba add Plutonium folder as exclusion https://forum.plutonium.pw/topic/8546/why-is-my-antivirus-saying-plutonium-is-a-virus-solution
Also you could try to use a VPN. You can also search the forum to see if someone had a similar issue and fixed it

cruzy Win + R type winver and send a screenshot of the window. Also what is your antivirus? (even if it is disabled or has exclusions)

ReyCuba try to delete the Plutonium folder in %localappdata% (while the launcher is closed) then start it again. If this still doesn't work then reply by saying what your antivirus is (even if it is disabled or has exclusions) and also if you have any VPN running or if you think your ISP could be blocking something

Spayyce what's your antivirus? (even if it is disabled or has exclusions)
