This guide is for anyone who owns a laptop with a mobility x2500 graphics card, and wants to get the very best out of it.
First of all make sure that you have the latest chipset driver for your motherboard;
if, like me, you have an acer travelmate 5720G, then what you seek shall be found here:
if not, intel's identification utility can be found here:
Note: To run the utility on Microsoft Windows* Vista, right-click on CHIPUTIL.EXE and click "Run as Administrator".
Match whatever chipset you have to the software on the intel site.
Once that step is complete, make sure to update microsoft's graphic control
driver by heading to the Device Manager, right-clicking display adapter,
and Update graphic driver then hit scan automatically online.
This is to make sure that the graphics card is identifed properly with the control file in the next step.
Okay next download the latest ati graphics driver with catalyst control center (currently 9.3).
Run the installer, let it extract to C:\\Ati, but cancel the procedure at the main install page.
Next, go to C:\\ATI\\SUPPORT\\9_3_vista32_win7_32_dd_ccc_wdm_e nu\\Packages\\Drivers\\Display\\LH_INF and locate file "CL_76828"
open the file in notepad and add the entry:
"ATI MOBILITY RADEON X2500" = ati2mtag_M56, PCI\\VEN_1002&DEV_71DE&SUBSYS_011F1025&REV_00
save the file
then go back to Device Manager again and update driver a second time.
This time click "Browse computer for driver software".
Then on "Let me pick from a list of device drivers...".
Click on "have disk".
Locate the folder "C:\\ATI\\SUPPORT\\9_3_vista32_win7_32_dd_ccc_wdm_ enu\\Packages\\Drivers\\Display\\LH_INF" again.
click on the updated "CL_76828" inf file
Now install the catalyst control center.
Make sure that you don't use catalyst's Anti-aliasing or AF, and use the application's instead.
Switch catalyst A.I to advanced for a slight fps boost in Counter-Strike Source and TF2.
De-activate virus scanners and anti-spyware before playing, as they can affect performance.
A good program to instantly stop these programs running is End it all2, which can be found here: http://www.docsdownloads.com/download/setupeia.exe
There you go! All up to date and as fast as can be.
I hope that helps
