Hi,
Just bought a new pc - Windows 7 64bit, Intel i7 2600k overclocked to 5GHZ with H70 cooler, 2x 2gb HD6950s in crossfire, 8GB Vengeance RAM and TX 850Watt PSU all on a p67 Sabertooth Motherboard using a 24inch HD Acer monitor.

I have bought the Witcher 2 and its running fine, average 62 frames per second on high but only getting around 28 on Ultra which i though would be much higher. On the menu screen, if i select the 'recommended configure' option, it always auto selects LOW???

I have updated the latest patches and sure something is wrong.
Any thoughts?

I know the system is ok as got over 200FPS on Crysis

This should really be in the Witcher2 forum, but w/e. In the config tool, start by using the "ultra spec" Config Set, then select "Show advanced options" and disable Uber Sampling.

If it's still slow after that, also try disabling Cinematic DOF. But really, saibling Uber Sampling should already make a huge difference.
