Hello CaptainsI know it's not a pmdg issue, but Im not a big forumer and 99% I'm here. After I updated my nvidia driver to the latest fsx won't start. After the welcome logo an error message pops up:"This graphics card does not meet minimum requirements for shader support. This product requires a geforce3/radeon8500 class or better graphics card. Flight simulator will exit now"I can only click ok then after a few seconds another pop up: Fatal error occurred, check solution or restart program. Obviously my evga gtx580 is enough for fsx. I tried to reinstall the nvidia driver but did not helped. Any help would be appreciated if it is possible to solve this issue without reinstalling fsx, because it takes ages to install all addons and setup widefs and simconnect.ThanksLaszlo

Maybe has some issue in OS. Try update windows. This situation is strange.

Thanks for helping!Strange indeed. Windows is up to date

I'm thinking your driver install got corrupted somehow. First thing is to switch windows update to manual so you have control over what it installs. Don't let it update your graphics drivers ever.Next I would try reinstalling the driver using the clean install option. Clean install is important.

I never allowed windows to install updates automatically and always downloaded nvidia drivers from nvidia.com and always performing clean install.Did the driver reinstall yesterday but not helped

You could open up your fsx.cfg, see what entries it has for video cards & delete the sections that shouldn't be there or have multiple entries. I've noticed FSX tends to make a mess of this & the new driver could have made it mess things up.

Unfortunately everything seems ok in the cfg file. Even if I delete the cfg file and let fsx rebuild that the same problem occurs

You might try the hardware & drivers forums then.

Ok thanks for your help

I wasn't much of a help, sorry for that.They might be able to get you on the right path more quickly over there though.

Just started a topic over there. Man I would really hate to reinstall everything. It takes ages. Thanks for the effort

This rings a bell, it or a similar problem came up a couple of years ago but alas, my memory is of no help today. The obvious is to roll back the driver version. Maybe an advanced search might pull the old topic up for you. Let us know what the resolution is once you get there.

Thanks Guys will try it tonight. Will report back what happened. After if it doesn't help I will do a complete reinstall because I wanna fly:)
