Huge lag while moving or turning screens

[asdfasdf]

<p>Windows 7 64 bit Enterprise with E8400 OC 3.6GHz and 4G rams, 9800GT (190.XX driver via Windows Update)</p><p>I have this problem since I upgrade from XP to 7, and due to driver issue I reinstalled the whole system including EQ2 a few days ago.</p><p>But it still happens, everytime I stand still I get about 40 - 65 FPS, and while running around or just turning screens will cause FPS drop under 10 or even 3-5.</p><p>I do not have another VGA to cross test this issue, so I cannot say it is a hardware or software problem tho....</p>

<p>Greetings,We have seen a lot of issues with the Nvidia driver version that you are using currently.  It seems likely that they are causing the problem in this case.  I would advise uninstalling your current driver version and installing version 186.  You can find version 186 at that following link:<a href="http://www.nvidia.com/Download/Find.aspx?lang=en-us" target="_blank" rel="nofollow">http://www.nvidia.com/Download/Find...aspx?lang=en-us</a>Please let us know if the issue persists after trying that step.</p>

<p>thanks, it works.</p><p>But it is a bit stupid which Windows 7's default built in driver for nVidia is newer, while I am installing it keeps telling me the the system didn;t install anything.</p><p>What I did is to stop the device and uninstall any driver files for it (including WDM version blablabla), and tell WDM to search the unziped 186 file for updates.</p>
