Counter Strike 1.6 Graphics problems

One day I got a ERROR “Unable to load authenticity record… Exiting”, I uninstalled and reinstalled the game. It all worked out fine, until I found these messed up colours. There where some blue on the tree leaves (when I get close to them they dissapper, and when I get two meters from the tress, they come back) and there where black tiles under the hostages. Also, when I play with bots, when I see a enemy bot, but computer lags like mad, I leave, it stops. This never happened before the error. Does someone have a solution? And I’ve re-installed 5 times, with the same result. Here are some facts if you wanted to know:
-the game is a fake from
-My computer (I know it’s old, but it still surpasses the recommended system requirments)
Intel p4 (1.6ghz)
512mb of RAM
64mb of Video
XP home sp3
Your help is greatly needed!!!
Answer #1
When you say surpasses, you’re extremely wrong, lol. You only have 512MBs of ram, and probably an integrated graphics card.
Lower the games video settings to lowest possible, and see if the artifacts go away.
Answer #2
same, thats what i did, lowest graphics the graphics can go. And remeber, this hasn’t happend before the incident.
Answer #3
Even integraded GPU will get you ~ 40-80fps in 1.6.
All I can suggest is that buy the original game.
Answer #4

if its too much work for you to check ur settings you may use a gui that most commonly tweaks graphic settings as well, eg:

those sites may be a good starting point for asking cs related questions
