I reverted back to the previous version via Steam, emptied cache and then re-installed the patch.
Didn't have launcher.exe in single player but first one apperaed after 15min on ATAG server. Before I could expect to complete at least one sortie (30min-1h+) before it happened. On this point I see no improvement, it has even gotten worse.
On the fps side, I went from an average ~30 online on ATAG to about ~45-50, so a good improvement, and also the game feels much smoother, I don't feel that kind of micro-stutters like before.
I don't understand how the team nearly doesn't see any launcher.exe while it seems it has gotten worse for a lot of us....that quite worrying...
Edit: launcher.exe happening also in single player quick mission, didn't happen with last version...
