Hi,

I've encountered a very odd problem: All of the sudden I'm not able to change the program settings in the Nvidia Control Panel anymore. I can change the settings and click Apply. But once I exit the Nvidia control panel and reload it, all the settings are back to where they were before I made any changes.

I use a GTX660 under Windows 8.1 and driver version 334.89. I'm using this combination for almost 1,5 years now and never had any problems. I also haven't changed anything on my system. So I'm really clueless on how to fix this.

Any help would be much appreciated!  :smile: 

Same here... very odd thing indeed. Haven´t changed the driver or anything like that.

Don't quote me but there had been some chatter a few months ago about how nVidia was locking down settings for their chips.  Now I don't recall if it was specific chips or everything in their nVidia line but it was to be executed through a driver change.  Now, i currently have a GTX-980M chip and if I used the latest nVidia drivers, I would have the same exact problem.  What I did was roll back to a driver version that did allow not only changes within the control panel, but also the nVidia Inspector.  I believe I am using driver version 353.30, which works pretty good for my hardware to sim (P3D).

 

I'm not sure why they did this, but I think it related to them wanting to allow the users to work with the graphics cards "as is", some sort of testimony to the new architectures (maxwell vs. kepler).  Again, don't quote me on this, but it was from what I gathered when I had the same issue months ago.

 

Give the older drivers a shot and see if they work for you.  A simple search online should bring you to nVidia's site where they have an archive of the drivers.

Interesting to see that I'm not the only one with this problem. Unfortunately I still haven't found a solution for this problem.

Thanks for the tip! But I'm already using very old drivers due to some TDR errors that I had in the past. As said I haven't changed anything. Maybe one of the recent Windows updates is the cause.

I'm a little late to this topic but I had exactly the same problem with my GTX 970 and found a fairly straightforward solution online. The first part of the fix is to get rid of GeForce Experience if you've got it installed. It would appear that it creates more problems than it solves. The second part was to download the Display Driver Uninstaller (http://www.guru3d.com/files-details/display-driver-uninstaller-download.html) which completely uninstalls your graphics driver - the Windows uninstaller can apparently leave a surprising number of driver related files which can affect the NVIDIA Control panel. Next, reinstall the drivers from NVIDIA, avoiding GeForce Experience, and restart your system. This worked for me after weeks of head scratching.

A fellow had the very same problem and couldn't get the control panel to save the changes. He did just what you suggested vortex681 and it restored his settings capabilities.

 

Using DDU uninstaller to completely remove all traces of the Nvidia installation and a clean re-install was what the doctor ordered.

Just to add to that, when installing a new driver, go for the advanced option, choose a 'clean install' (this removes the old driver) and finally after it's installed delete the Nvidia folder from the root of your OS drive. And as mentioned above, NEVER install GeForce experience, it's just an unnecessary system hog and it will constantly bug you. I learned all of this from Nick Needham's FSX bible, so credit to him.

Thank you so much, this cured the problem which has been real wonder to me for a long time. Excellent job guys!!

Better late than never.

 

Just found this today. Hope it helps those who have been having problems where settings aren't being saved by the Nvidia Control Panel.
