Since Alpha and Beta releases I've a permanent crash in game startup until this final product release. The problem was the same "DirectX 10 is not supported by your adapter". I tried all the tricks that I founded in several forums (-winxp, -nobenchmark, reinstall Nvidia drivers, validating integrity of cache, development builds, ... ) without success. I used Arma 2 for a long time without problems. But Arma 3 is impossible to start.

Extract from rpt:
