I uploaded more .rpt and .bidmp files for the crash I had today on a multiplayer, deathmatch 'airstation' map (custom scenario). The game started out and ran fine, then for about 10-15 minutes of the game I noticed a framerate drop that consistently made my video/framerate a bit more choppy and laggy but was still playable. Finally the game crashed with the following error in windows:

As a side note I noticed this problem was related by MadDogX, issue 0006904. Looks like exactly the same issues I'm having.

I uploaded .rpt and .midmp files, however I have a recent .mdmp file that is around 9mb and even when it is compressed in a .rar to 2,523KB I still can't upload it (file is too large error message pops up).

Hopefully the ones I did send can help though. I believe you should already have my dxdiag information.

Astaroth-

It seemed for a while that this issue had slowly gone away but I experienced it again tonight playing another custom scenario (TDM Forest East) multiplayer PVP. My shadow settings are set to standard along with many of my other graphical settings.

This crash has become a lot less frequent for me but it still is an occurring issue (in MP only it seems)

Astaroth, I'm not sure where to get 'dxidiag'. I know how to *run* dxdiag, most of the information I have from it has been posted above in the problem descriptor. Can you be more specific if you need an actual log or file? According to the "how to guide" you posted, dxdiag can only *show* information in windows 7.

I uploaded my arma 3 alpha files under the main file upload tab. I'll try and give the standard settings a shot too and will report back in a day or two.
