On my system, the frequency of Launcher crashes is proportional to my video settings. I have reverted back back to Med settings for everything except Model/Damage Detail to High, Trees/Shadows/SSAO/AA Off and Vsync disabled and Triple Buffering set to off.

I also try to avoid excessive use of the zoom function when particle rendering is taking place which seems tied into the 'effects' setting.

With the above I can be in MP for a lot longer without the dreaded Launcher crash and my fps is much higher even over the dreaded low altitude hot spots.

After fitting a 2gb GFX card, I cranked the setting to High and started getting LE crashes more frequently.
