I was having alot of lag today while playing SK . Tried alot of things to fix it :
1. Restarting Steam
2. Restarting the router
3. Clearing Game Cache ( Not sure if it helps )
4. Restarting the whole computer
After that , I saw some posts that suggest putting Graphics on low ( Which I am using ) and unchecking all other boxes . After I did that , I tried to log in with my Steam Account , but it says the following :
"We experienced a problem authenticating with Steam..."
As before , I tried restarting Steam and clearing game cache but nothing is solved .
