Most got better. Unfortunately, there is no hotkey for D3D, so I tried to get screen shots that were as close to each other as possible for you to compare. I will look into it though. Detail settings on all games were at maximum possible settings. Numbers listed are an average.
All frame rates are from inside the default cockpit.
Rogue Spear is from the first person perspective. As you can see in this matrix, many games did not perform as well on the V5 as they did on my V3. I will attribute this to driver maturity. I am using the very latest drivers on my V3. FSAA X4 was the same as non-FSAA on my V3 3500.
