Hello,Could someone please advise. Installing on a standard WinXP home system, I'm seeing much improved frame rates.However I'm unable to apply the usual LOD bias fix with Riva Tuner, and setting AA in Riva Tuner to "forced" still results in having to switch AA on within FS9, which previous drivers did not need. I believe switching AA to forced before running FS9 results in better performance.Finally, the 52.16 Nvidia display menu fails to load with the message "catastrophic failure". There is no opportunity to manually set the LOD bias, without which I cannot fine tune the anisotropic settings. Thanks for any wisdom.Rob Young

Hello Rob,I do not use RivaTuner anymore, I run the starstorm drivers (see Guru3d.com) , most of the job is already done .

Hello RobDid you download the "English" version of the 52.16 drivers. I tried this yesterday and got the same "catastrophic failure" in NVCPL when trying to look at the Ti 4600 Tab in Display Properties.Rolled back the driver in XP and downloaded the "International" version of the drivers which installed and work OK.Hope this helpsIan

Hi,I observed a fps gain too. I also had the problem with the catastrophic failure in the display tab properties which was solved with a fresh install of the international version as advised by Ian.

Hi Ian,Thanks for the tip; I got the same Catestrophic Failure, then when I clicked OK to that box, up popped this one; see attachment. So I'm going to follow your advice and go for the International version.kenSomerset, England

I got the same catastrophic failure when installing the 52.16 drivers. I stuck to the English version (8.12 or so Mb). Try the following: Run the installation file. This will create a folder 'Nvidia' which will contain the extracted driver files. After extractionis complete, you can decide to go ahead with the installation or quit immediately. The important thing is to emove the drivers (uninstall video card drivers) presently currently installed on your system, reboot, and when prompted by XP that new hardware is found, make sure you do not close the prompt and try installing the drivers from within NVidias executable setup file. Stick to the new hardware prompt generated by XP and use it to browse to the location of the 52.16 setup files (In the Nvidia folder created during extraction). Then it's a matter of letting windows do the rest.It worked for me although I noted the frame rate difference in Full Screen and Window mode.Storm

Thanks all for good tips and advice. All well received.Rob
