I have tested alot to fix that and finally the most simple thing helped.
-deinstalled my grafic driver and restarted the computer
-deinstalled MWO and restared the computer
-installed grafic driver in the latest version and restarted the computer
-installed MWO and restarted the computer
-go to MWO grafic options and turn down enviromental,texturing and post processing a little bit
Before i done this :
-crashes every second or third game
-major bugs every game or every second game
after :
15 games streak without crashes
2 out of these games had bugs
edit:
memory allocation failure is a cryengine 3 error.These steps may help a bit but at least PGI has to fix it.
This happends to both, high end and lower pcs. Turn down enviromental,texturing and post processing helps a bit to prevent that cause they are the most ram eating things.
Cryengine is using ENB technology wich is very v ram intense (ambient occlusion,depth of field,hdr lighting and motion blurr).
This is a general tipp. If you have problems with laggs this is the adress.Turn those options a bit down and the laggs stop. you wont see any big difference but you gain alot performence
edit 2:
sometimes it happenz that MWO conflicts with firefox or internet explorer.
Try to turn every not needed backround program or browser off.
edit 3:
Deinstalling MWO everytime before an upcomming patch and download it again with the new patch included is also a good idea because if you only patch script issues can show up.
This is basiacly all i know what you can do the rest is up to PGI.
