game just crashes at start for meIn case this helps anyone, after 5 days of pulling my hair out, I found a (shoddy) workaround that works for me at least. I think the issue was caused by a Windows 8.1 update. I just built a new system and upgraded from Windows 7 to 8.1, and that's when the mod stopped working. So here's what I finally did:
-Make sure all your C++ stuff is updated (the links are back a few pages in this thread if you need them)
-Download and install the Rome 2 version of the mod, to your Rome 2 folder, follow all of Lucifer's instructions for the Rome 2 install
-Subscribe to the Rome 2 GEMFX mod on Steam
-Run the game once so that it downloads the Steam version of the mod
-Now run the 'gemsteaminstaller' shortcut, located in your Rome 2 folder
-Now copy all the 'GEM' files and 'dxgi.dll' in your root Rome 2 folder and place them into your Attila root folder
-Also make sure to grab the 'gem.pack' file from the Rome 2 data folder, and place that into the Attila data folder
-Run the GEMFX configurator in your Attila folder and set it to 'Compatibility Mode'
-Now run Attila either through Steam or the mod manager, and make sure you check 'Gem.pack'
-If you're in luck, it'll run, then tweak your settings and swap in Lucifer's 1.0.8.1 patched dxgi.dll for Attila if you want, not sure if you need it
Hope this helps someone. I tried every other solution in the forums and this was the only thing that worked for me on a fresh Windows 8.1 install.
