DigitalFoundry has released a Work in Progress Frame-Rate Test for Halo 5 Guardians, based on the Gamescom gameplay presentation of the upcoming title from 343 Industries.

　　DigitalFoundry explains:

　　We had the chance to take another look at Halo 5 Guardians at this year's Gamescom. Although different levels were shown compared to the E3 campaign reveal, overall performance does show a clear improvement - a state of affairs backed up by this collection of b-roll clips Microsoft released this week, with good clean performance marred only by a sub-optimal cut-scene at 00:29. More interested in multiplayer performance? Skip ahead to 01:38.

　　The official Xbox YouTube channel has made available a Halo 5: Guardians Campaign Behind the Scenes Teaser for the Xbox One Exclusive, which can be watched below:

　　A mysterious and unstoppable force threatens the galaxy, the Master Chief is missing and his loyalty questioned. A Hero Reborn ViDoc takes you behind the scenes of the most dramatic Halo story to date in a 4-player cooperative epic that spans three worlds.

　　You can watch the entire documentary now on the Halo Channel. The Halo Channel is currently available on Xbox One, Windows 8.1 PCS/Tablets, IOS, Android and coming soon to Windows Phone.

　　DigitalFoundry has recently released a Frame-Rate test from the E3 2015 presentation of Halo 5; Guardians, which can be viewed below:

　　E3 work-in-progress footage. 343 Industries is aiming for 60fps gameplay, but it's clear that there's a lot of optimisation work to do - and we suspect that could well be down to CPU as well as GPU.

　　Already, 343 is looking to free up as much GPU time as possible - as well as lower resolution transparencies effects (explosions etc), there's a dynamic horizontal resolution in play here, while vertical resolution is locked to 810 pixels right now. But 343 says that nothing from E3 resolution-wise is final - but we can definitely see the techniques it is currently using in an attempt to keep frame-rate high.

　　DigitalFoundry explains:

　　The current dynamic frame resolution system can actually be observed in more detail within the 'Road to E3' video published on the Halo Channel a few weeks back, and embedded below. It provides a closer look at the game in a debug state, complete with important performance statistics visible on-screen, as the camera is flown in and around the environment. We can see the horizontal resolution apparently shift dynamically between a full 1920 all the way down to 832 pixels. With 810 vertical lines in play we're looking at a resolution ranging from 1920x810 to 832x810. However, in b-roll distributed during E3, minimum resolution observed comes in at 1152x810 - not exactly wonderful but presumably more indicative of where the system is right now during gameplay.

　　We will bring you any new information on Halo 5: Guardians as soon as it becomes available.
