Patch 1.04 aimed to fix performance issues of urban (city) area. It was one of the main part of 1.04, but nothing happened, this bug is not fixed. It isn't mentioned in the 1.04 patch log either, and if you check, the FPS is same or wronger than with patch 1.03. If BIS promise something why can't they solve it, it's a shame. If the 1.04 was the performance patch, then why I couldn't realize any performance boost!?!? Operation Flashpoint 2 will be released on october 6, and arma2 is a chaos now, and a performance hit on a PC. What does BIS expect to after Operation Flashpoint will be released!?!?!
