I can confirm the rendering resolution difference between the next generation consoles. However in our case, the difference between the next generation platforms is very small. We are running exactly the same shaders/effects without any difference in quality on both platforms. Antialiasing and texture filtering quality is also identical. Neither console has any advantage in frame rate (vsync locked 60 fps on both). Xbox 360 is also vsync locked 60 fps. All three are butter smooth and offer the same high quality Trials game play.
I have been playing the game myself on an Ultrabook (ultra lightweight laptop). The recent PC beta patch improved the frame rate on low end GPUs by 40%, and this means that my laptop now runs the game at locked 60 fps (1600x900 resolution, "Normal" settings). We are trying to scale the PC version hardware requirements even lower in future patches, to allow more people to enjoy the game the way it's supposed to be enjoyed (at vsync locked 60 fps).
As a friendly remainder: I will not participate in any console wars. Please don't try to drag me into PS4 vs Xbox One discussion. This is a new situation for us, since we haven't been doing multi-platform development for long long time. I am not used to these kinds of debates. The last time we did simultaneous multi-platform development was in 2008, when we released Warhammer 40K: Squad Command simultaneously to Sony and Nintendo platforms. Back then everyone just enjoyed their games instead of fighting over a few extra pixels on the internet
