I'm running Windows 7 64-bit. I downloaded the 64-bit version of NHancer and installed the software. A desktop icon is on the desktop. However, when I execute the program (under Admin priv), the banner appears but there is no indication that the program is running and there doesn't appear to be any way to access the user interface. I've downloaded the software 3 times thinking there might be a problem with the downloaded file.Can someone please help.ThanksFrank

NHancer is outdated. You want Nvidia Inspector. Get it here: http://downloads.guru3d.com/NVIDIA-Inspector-1.94-download-2612.html

Thanks superglide. I'll check that out.Frank

Check THIS for configuring Nvidia inspector for FSX use.

Ben,Thanks so much. That link was very useful. Muchas grass.Frank

I am a bit confuse. I had to replace my ati 4850hd in my computer so I desided to go with nvidia. I removed all ati drv. stuff and installed the lastest nvidia drivers from there web site. I noticed in the control panel there is a section that shows FSX and it has certain settings alrealdy. Are you saying to leave this as is and install the nvidia inspector and make the changes as suggested? Or, do I try to make the changes in the control panel. I must say that currently, my frame rate is much worst with Nvidia. I use to have the frame limiter set at 30 and it seem to work fine in most cases. Now when set to 30 it runs between 15 and 18. Please advise.cp
