Tetris

Hi all, I sure hope someone can help me as I'm dying here without being able to play ArmA 2. So I'll start with my system specs: Intel i5 3210M, Intel HD 4000 iGPU, 6GB RAM, 1TB 5400 RPM HDD, So anyway. I bought the ArmA 2 complete collection on Steam nearly 3 weeks ago now after having played ArmA 2: Free for 3 months and thoroughly enjoying it. On ArmA 2 I'd get an average of 20 FPS, and generally the same on ArmA 2 OA. I was getting roughly 15 - 50 FPS dependent on whether I was flying, in a city/town ect. This was with the following in game video settings: Texture Quality: Normal Video Memory: Very High Terrain Detail: Normal Object Detail: Normal Shadow Detail: Off Post processing: Off Vsync: Off AA: Off For a good two weeks, I was loving the performance (for my system) and it was very playable for me. Last weekend though, I went off for a few hours in order to get some work done and upon joining any server when I got back on, I was greeted with slow-loading textures, stuttering, lag, and low FPS in game. The loading of multiplayer mission files was also awful, for example, it took (and still takes) 5 minutes for a Takistan Life MP mission to load up so that the keys for that mission can be used, shops accessed ect. I have no idea what happened. I didn't change any video settings, and it just went like that. I've reinstalled the whole complete collection of games and it's still the same story. Prior to uninstalling, I had no game mods other than City Life 2 RPG. I have defragged my HDD, reinstalled ArmA2, OA and all DLC, making sure that all files related to the games were deleted before reinstallation, tried some suggested fixes online such as editing the config files but nothing is working. I just want to be able to play the games again like I was able to before, at a good steady 20 FPS or 40 FPS when I fly as CAS. Help me! :(
