I'm going to take advantage of this topic my friend, so I don't have to create a new one.
I'm also having problems since I built a new PC. Every time I open the DCS, I have to try 3 or 4 or 5 or... times until I succeed. On the first attempts, it always hangs on a black screen, before showing the loading bar.
I'm running the most current beta version, with mt.
I've already tried some solutions, for example:
Delete the folder in Saved Games, DCS.openbeta;
Repair in slow mode;
I don't have any mode installed;
I've already run the MemTest86 mem ram test.
My last log file is attached, which was just now when there was a strong crash during DCS initialization, but which arrived at the initial screen. I saw that there are some error lines.
Thnaks guys!
