Please try this. (I have an older model XPS 600 running a an old 7900GTX) and it was forced into MED settings in graphics in ETW which I had problems with so I backed off to low then.
NOW is a new story: Same system and still forced to MED settings but I found this help and decided to try it out seeing that I had no graphics issues on medium settings and I was very angry about "disappearing dead soldiers" and was told HIGH setings would cure this.
Simply go to your scripts file and change this:
gfx_video_memory 0; # gfx_video_memory <int>, Override available video memory (bytes) #
to this:
gfx_video_memory 512000000; # gfx_video_memory <int>, Override available video memory (bytes) #
I was ASTOUNDED at graphics Iv'e never witnessed now that I was allowed to change my settings to HIGH...ASTOUNDED...THUNDERSTRUCK...AMAZED...COMPLETELY BLOWN AWAY. It's a whole new game! ! !
Iv'e been missing out!
Incidentally, those "disappearing soldiers" are now not disappearing but remaining for the duration.
WELL DONE DEVS WELL DONE what a beautiful game!!!...I might try ultra...who know but they really improved the graphics management and pleas give that old machine a try with this change...you might be amazed too.
