Plutonium

I had Black ops 2 from plutonium but it lacked the single player so I got the base game on steam and weirdly I'm experiencing some weird lag spikes when in games. And my ping jumps from 20-999 randomly. It has become so annoying that I cannot play the game anymore. Are there any fixes for this? Its weird that I'm even lagging on a high end computer.
That has a RTX 20 series gpu.

@FudgeJudge Is that all? Whats the other sv_cheats commands?

Im having the same problem. I play a game of zombies, and i get horrible lag spikes even on a goddamn high end computer with good internet. I even lowered graphics to vomit and still lag spikes.

JezuzLizard Its not possible to buy Black ops 2 on Steam. Its price is butt ass high. Buying it would be giant financial loss.
