No, I could not get SoftTH to work with CMSF.
CMSF only display on the center ( primary ) screen. I've edited the display size.txt file ( 5760 1200 60, 3840 900 60...etc..etc.. ) and the new resolution setting does showed up in the option menu , but it has no effect. I have also tried all the monitor display settings from the TH2G web site.
I've got SoftTH to work with other Battlefront games ( TOW I, II and PT Boat demo, I even got Steel Beasts to work on three monitors ) , just not CMSF !!. which is a huge disappointment, because CMSF is still the best out of all the battlefront games, IMHO, and it should be played on thee monitors or more . I was hoping to get the three monitor setup working before the upcoming Normandy and Afghanistan titles.
Any other suggestions to make CMSF work with multi monitor setup?... and if Battlefront need someone to test Eyefinity with CMSF ... ;)
