I am one of the people who get the freeze/launcher stopped working crash while I play online with the ATAG Server alpha patch, and while playing single player. I have sent many crash logs.
BUT NO MORE IT's FIXED!
I was on the ATAG Server late last night and had no lock-up or freeze screen problems for around an hour and a half of flying then I logged off, after I carefully read all the posts here and gave it one more try.
What I did after appling the 1.6 alpha patch:
AA off
SSAO ON
VSYNC ON
GRASS ON
SHADOWS ON
ROADS ON
FOREST OFF (Yes Forest off not a typo)
BUILDINGS AMOUNT LOW
TEXTURE QUALITY MEDIUM (This one is important if you fly the 109 because if its set to low then I can't see the gunsight cross and circle).
The rest of my settings are set to lowest possible except the special effects feature that shows the Mine shells explode and burning vehicles etc. This is important of course so you can see hits and if the target is destroyed.
Before when I had the crashes all this stuff was off. Now my problem is low frame rates 20-32 because I have an OLDER Geforce GTX 260 1 G Ram, but this FPS is actually an improvment over the 1.5 patch which gave me 10-20 FPS when I had grass turned on and graphic setting high etc.
Hope this helps people how are still having trouble I fixed mine by following these guys suggestions here and it worked. Now I need to upgrade my Video card and I'll be in business
