FPS seems to get worse compared to the last beta patch. On the bright side, low-textured cockpit issues are gone. Now they are beautiful.
Weapon hit effects are still as the last beta patch. In the last official patch, it indeed looked like puff of smoke. Now it looks like some flickering black cloud.
AI doesn't do insane F-16 roll anymore. Instead they turn to scissor. AI still knows where your pipper is, so they maneuver around it. AI can fly very fast and does not seem to be affected by overheating or negative-G.
Other AI issues are: AI crashes too often (almost as much as I do

); when AI bounces on you from above with massive speed advantage, if you try to throw his aim off by a hard turn, he follows but cannot shoot and ends up crashing on you from behind.
Elevator control is very unresponsive. Perhaps that's why the 109 stalls so easily now. This bird requires very dedicated joystick control.
Collision is still as buggy as ever. Very often one aircraft explodes or gets mortally damaged, why the other escapes untouched.
All in all, a nice beta patch that goes on the right direction. Keep up the pace!
