So I downloaded the 1.5 beta using the OpenBeta Standalone Client and it seemed to have installed/downloaded successfully.
However, whenever I run the 1.5 singleplayer or multiplayer exe, the game simply blackscreens and stops responding straight away. I can still hear the menu music in the background when this happens, and the game changes my screen to a lower resolution until I end the process.
I have tried updating/repairing using the DCS_updater cmd stuff, I have checked that my drivers are up-to-date and I'm pretty sure my computer meets the minium req's.
Have attached my dxdiag and latest dcs.openbeta log. DxDiag.txt Logs.rar
