Mengis,
Welcome to Sevenforums to you!
I will be providing you with links that you may click that lead to a tutorial part of this website for a how-to.
Make sure you have windows completely updated, along with every one of the games. Also, make sure your
drivers are updated, especially your graphics
driver. If you'd like me to find the appropriate one for you and a how-to, fill out your
system specs with this
tool.
Try putting your game into compatability mode:
Compatibility Mode
Failing that, lower your graphics resolution and settings through your graphics control panel. If you'd like more of an explaination, please ask.
It is unusual, but some antiviruses may get in the way of the game. While I don't recommend disabling a much needed antivirus while connected to the internet, you might try it as a test. What antivirus do you use? I can offer recommendations based on how well your antivirus performs according to my experience, if you would like.
To more easily find
drivers compatable with your computer, you can set windows to find them auatomatically:
Compatibility Mode. Then you can check for updates and see if there are any "optional"
drivers available to you.
