The search function of the forum is broken, but that's not the problem. It's the reason I'm asking this though. I suggest you look into fixing the search button.
I used to play Retail MW2 and after that AlterIW on a multimonitor setup using a direct3d injection to make it work on my non-eyefinity graphics card. I also used a tool to set my aspect ratio correctly for such a resolution. On AlterIW, one of those caused a ban for me once, which was lifted quickly - thanks former aIW staff. After that I played it on a wimpy single 5:4 monitor.
Now I have an Eyefinity capable card, I do not need the d3d injection anymore, but am I safe to use a tool to properly set my aspect ratio and align the HUD? It'd function by means of modifying a few memory values during runtime.
If I better not, may I do an open request fdonet implements better Eyefinity support like Battlefield, Dirt and all those games do?
