Got two hard crashes online tonight. First was white screen with audio looping. Happened msec after I killed an enemy tank in town and the explosion sound looped. Ctrl-Alt-Del Task Manager could not stop the AH process. Had to physically reset the computer to regain control. Second time was a black screen and Task Manger was able to kill the AH process to regain control. Retrieving an error message was impossible in the first case and I forgot to in the second. I mention it to show that in addition to the reports of the DX11 crashing, the DX9 version does as well.
The 17lber AT gun in the large town (ca A48 on CraterMA) is not useful because the combination of surrounding trees, bldgs, and the fact that it is on a hill and cannot depress enough to shoot down, makes virtually all but a few degrees of the 360 deg arc useless.
