Rage3D’s member ‘Napoleonic’ has spotted an fascinating PDF from Ubisoft’s Far Cry 3 GDC 2012 presentation. Within this presentation, Ubisoft has highlighted the differences among the Computer and also the console builds of Far Cry three, and revealed that a number of the graphical effects shall be offloaded to the CPU in an effort to conserve some extra GPU cycles.
Now as you may have guessed, this offload routine was implemented in an effort to optimize the game to consoles. It’s popular that existing generation consoles can’t push excellent visuals unless developers offload numerous GPU instructions for the CPU (SPU for PS3). The problem right here is that the Pc version will most likely suffer from this particular console optimization.
Not only that, but given the console’s framerate target (30fps), Ubisoft may well not optimize the Pc version for older CPUs. Our guess is the fact that they’re going to, the moment once more, rely on the extra raw power of current-generation CPUs to overcome their laziness, and that’s anything genuinely unacceptable. What’s even funnier here is the fact that CPU specifications could be lower, supplied there weren’t these console optimizations (and yes, even high-end CPUs would advantage from some thing like that).
Ubisoft will probably be also undertaking their finest to keep the memory specifications to low levels, some thing that – as soon as once more – is on account of console’s hardware. In accordance with the GDC 2012 presentation, the world in Far Cry three is composed of maps, which are divided into sectors. Each and every sector is 64 by 64 metres and includes roughly 70 probes. With each other using the 3D grid, that is utilised for spatial indexing, this brings the memory consumption per sector to a little bit much less than 15KB.
In total numbers, the game features a highest of 51sectors around the player loaded in memory at any 1 time, so theoverall footprint in-game is about 760KB on consoles, and around 11.5Mb on Pc.
Contrary for the console versions, the Computer version will function distant light sources – suchas the sun as well as the sky – and support for worldwide illumination from dynamic lights. This is specifically handy for night time scenes. Ubisoft also bakes neighborhood radiance transfer. Using that, the organization can approximate international illumination from dynamic light sources with a approach referred to as ‘bake local radiance transfer’.
Additionally, Ubisoft has implemented a blur effect on the volume maps for the Pc version so as to soften the irradiance, an impact that may be not present on the console versions. This effect is said to provide Ubisoft additional gradient levels, specifically together with the occlusion brought on from the vegetation.
Far Cry three is currently planned for a November 30th release on Computer, X360 and PS3!
