For me (ATI Radeon 6xxx card, old Intel Core Duo chip):
* New shadows worked, and worked as spected
* Saw an improvement (not that big on my setup) increase in framerate
* Saw a couple of weird plants on Quesh, but not seeing any other artifact or render issue apart from that.
* Shadows have a penalty on the framerate. But any game that has shadows ON has a penalty on frames. Sometimes the penalty is big, sometimes is not. But if people want MAX framerates, then...
Turn Shadows OFF.
PS. Later gonna try the game on my latop (ATI Radeon 6xxx mobile, AMD Quad-core chip) and see how it behaves.
It stutters with max FPS.. how about that!? MUST be the FPS and the hardware, hmm?
