The client flashes briefly, I get a white window that goes fullscreen and after a second I see my desktop and get G25 error page. After a while the launcher closes itself. Live client works fine. I am providing a screenshot of the error page and what geforce experience shows me about my rig. I did run file validation, the test client is a fresh download.
I am also experiencing this issue and I have copied the above users steps, can confirm my live client works fine as well with my rig.
This is happening to me too, and I have a GTX SSC 960. I bet it has something to do with them switching over to DX11.
This is STILL happening to me as well... I'm running a Radeon RX 570, but that probably doesn't matter since EVERYONE no matter what they are using is crashing upon booting the PTS client.

Any idea why the DB guys seem to respond on twitter and reddit and everywhere else and only very rarely in the actual forums?
