I run it at true full screen mode on my 4890 1Gb.

Before the latest patch i could still get it to use the correct clock speeds by renaming the Ubi logo (since it would "confuse" the drivers and it got stuck at 500Mhz if the logo was displayed), but it seems that my fan speed and voltages weren't adjusted along with it and i would get reboots after 10 to 40 minutes of gameplay.

With the latest beta patch i set it to true full screen and everything is fixed, plus i get a smoother frame rate overall as well. I logged the GPU's parameters with GPU-z and even when under 100% load the temperatures are normal, plus it also automatically adjusts the voltage to give steady performance.

Running the latest patch on full screen - no issues.

S!

Full screen works for me as well.

5970 here and works well in fullscreen... in psuedo mode it's like the previous patch for me ie no crossfire and tearing and stuttering like crazy.

Disabling the UBI logo thingy at the start (and turning off mirrors) gives me about, on average, 40FPS improvement. Still get some stuttering over London, but then I do have all my settings on high.:)
