Hi there

Firstly, your English is quite good for a non-English speaker. Ok, now to the problem. Can you please let us know which game did you install? As a general solution, I would recommend you to update your Graphics driver. You may also want to update the physix driver. The easiest place to do this is to go directly to Nvidia website. Go there, search for your product and download the latest driver. If you wish, you may look for Beta drivers as well.

In most of the cases, the suggestion above should be helpful. I used to face the same situation before but after installing the new drivers the problems went away. Lastly, there are some games that have very heavy graphics demand and no matter what you do the game will never run smoothly on the laptop. For example, Crysis. I was never able to run this game well on my XPS1730 (I have a 8700GT Sli card). The funny thing is that the game never ran smoothly on my new PC with a 9800GTX Sli card. Some games are just optimised for certain hardwares. Crysis is optimised for 8800GTX/ 8800Utlra.

I hope my suggestion helps you.

Regards

Amit

I am strugling with exact thing now. I blamed game at first, tried many, many drivers.

I have bios up to date and Vista update on. 

What I noticed is just before CPU usage goes nuts  CPU clock is dropping to somethng like 300 at the end. I would expect it to be related to temperature but everest says gpu1 90, gpu2 90 cpu 60 or something around. 

I know how weird it sounds. So after a while it gets to normall. By some time I mean periods from 1 to severall minutess.

So I am curious how hot is your XPS and what is the clock when you have this?

Try trial of everest it is rally handy...

Thanks Amirage for your reply.

The game I was writting about is "The Witcher - Enhanced Edition" (polish version) - have no idea, if you know that game. As I remember the game base on graphic engine used in "Neverwinter Nights" game (I hope the title is correct) - maybe this help to solve the problem. I also played the "Medal of Honor - Airborne" game, and had the same problem, except sounds and music. With "Company of Heroes" game CPU worked on 73-78%.

 I hope that you're right with drivers, but for  results we must wait, because currently I have no internet access, and also I must find drivers for my graphic card (I found out, that nvidia doesn't issue them for laptops) - they are on laptopvideo2go.com, but I completely don't know which one shuold I use. Anyway I will give you a shout about results, when I manage with drivers.

Hi there

To me it sounds like an issue with the graphic driver. You can visit Nvidia.com. There click the link for download drivers. Here's the link: http://www.nvidia.com/Download/index.aspx?lang=en-us. In the product section , select GeForce M/Go. After this, then click the model. Then, you click version of windows. 

Let me know how it works for you.
