Anyone know how to fix this?

There's a problem with dForce if you have the latest nvidia game drivers. Using the studio driver or rollback to an older driver version.

I tried that, and it's still broken after a clean install of the previous driver AND a reboot of my PC.  I tried both the Studio and the Gaming versions - same results.

I'll see if I can find where NVIDIA has all their previous drivers.  It's pretty crazy an update would cause such and error.   I guess the question that we might not ever know is... will it get resolved by NVIDIA or does DAZ need to fix something???

In the mean time, thanks for pointing me to that thread.   I'm off to see if I can find older versions of the 1080Ti driver.

I did one of the things that thread suggested - went in to control panel and uninstalled the 1080ti and told it to remove all files.   It then re-found the card and installed it.   That fixed my problem.

Thanks for pointing me to that thread.   I'm a happy camper thanks to you.  :)
