Hello,
Just giving my feedback, for the experience of my last 2 days.
Reinstalled DCS after something like 6 months, or so, and ran into a major issue that was causing my game to CTD after less than 1min flying most of the times.
After some testing I came to the conclusion, pretty early on that it was MSAA 2x causing my crashes. The fix however was not so easy, as just turning it off was too impacting IMHO regarding visual quality and image stability. After trying to find similar reports, i found a suggestion, that actually increasing MSAA to 4x fixed the crashes.
After trying it out, I confirm that it solved the issue. Tried it in different scenarios and had no more crashes.
Just leaving it here, to help the next guy.
