I noticed that my Counter Strike: Condition Zero game is not as smooth as when internet is not connected.
I mean when I walk/run in game, the screen hangs (hang could be a wrong word here) for milliseconds. It's very subtle but irritating. So overall, game is not smooth. I think it is called FPS drops.
Note that I don't play online game. I just play Tour of Duty in this game, which requires no Internet.
One way to fix this problem is disconnect Internet when I play, but I don't even understand how Internet is messing up with the game.
I feel it is somehow trying to connect to internet, don't know why would that happen when offline version don't need Internet at all. Could it be because of
platform/config/MasterServers.vdf file? I saw there are lot of IPs.
Today I noticed that it wasn't happening to this game only, it is happening with 2 other games I play, GTA5 and COD4. Earlier I thought it might because my Graphics card is not strong (940MX), but even when I play at lowest settings, I saw this non smooth fluctuations in the games.
So I feel it's definitely not because of Graphics card and my PC (which is i7 processor, 16 GB RAM). Because CS:CZ used to run pretty smooth even with Intel HD graphics. And it consumes very less RAM.
This similar problem I face when my laptop is not plugged in for charging i.e., it runs on its battery. But I guess that is a power related issue and makes sense.
So what could be the reason? All of these games I play in offline mode, Internet not needed. Can Wi-Fi Internet really mess up with games like this?
