Error at startup (Assassin's Creed)

I found everything, thanks to WHATTiB: https://yadi.sk/d/W8-tN3aPkcP98

In order not to create a new topic with the same name, I will ask a question here. Maybe someone knows why the first part on win8.1 x64 does not start in dx10 mode? Only in the 9th

I started all the rules and on 10 too. Probably you have a problem.

It is clear that I have a problem. Only I can't find her, so I asked. Maybe someone else had the same problem

NatanieLzZ Have you tried
standard reinstallation of the game and drivers?

4epushilo
Yes. GTX 650, drivers from fallout 4. I also tried to install older ones. The Win7 compatibility mode, on which everything worked, did not help. DirectX also reinstalled
