I had ArmA 2 in 1.01 nicely up and running with a Matrox TH2G in a 5040 x 1050 resolution.
After applying Patch 1.02 build 58134 I got the infamous message "Error creating direct3d 9 graphical engine".
I did the usual troubleshooting: -winxp parameter; removing config files; lowering memory in msconfig to 3070.
To no avail.
I did a rollback to version 1.01 and the ArmA 2 was running ok again.
Looks like Patch 1.02 build 58134 doesn't like Matrox TripleHeads2Go.
Also there might be a difference between the normal (<= 3840 x 1024) TH2G resolutions and the widescreen TH2G resolutions (up to 5040 x 1050, only with nVidia 200 series graphic cards, like the GTX 280 or 285).
Is anybody out there with a TH2G who has it up and running with Patch 1.02 build 58134 ? And in what resolution ?
