Subsequent week, Ratchet & Clank: Rift Apart is launching on PC! Lots of you will have requested for particulars concerning the applied sciences used and system necessities. Immediately we’re answering these questions, and on high of that, we’ve got some thrilling new characteristic bulletins.
To make sure a easy dimension-hopping expertise, our crew applied DirectStorage 1.2 in Ratchet & Clank: Rift Aside on PC, together with GPU decompression.
Richard van der Laan, Senior Lead Programmer at Nixxes Software program, explains: “To allow fast loading and on the spot transition between dimensions, the sport wants to have the ability to load property shortly. DirectStorage ensures fast loading occasions, and GPU decompression is used at excessive graphics settings to stream property within the background whereas enjoying. Historically, this decompression is dealt with by the CPU, however at a sure level, there is a bonus to letting the GPU deal with this, as this permits a better bandwidth for streaming property from storage to the graphics card. We use this to shortly load high-quality textures and environments with a excessive stage of element.”
Principal Programmer Alex Bartholomeus: “For Ratchet & Clank: Rift Aside on PC, we added adaptive streaming primarily based on dwell measurement of the out there {hardware} bandwidth. This enables us to tailor the feel streaming technique for the absolute best texture streaming on any configuration. With DirectStorage, using a quick NVMe SSD and GPU decompression, this leads to very responsive texture streaming even on the highest settings.”
DirectStorage is developed to completely make the most of the pace of quick PCIe NVMe SSDs, however the expertise can be appropriate with SATA SSDs and even conventional onerous disk drives. This implies Ratchet & Clank: Rift Aside on PC can use the identical expertise for loading information, whatever the storage machine in your system.
Ray-Traced Ambient Occlusion and XeGTAO
In our preliminary announcement, we shared that Ratchet & Clank: Rift Aside on PC will characteristic ray-traced reflections and newly added ray-traced shadows for pure outside gentle. Immediately we are able to reveal the addition of another choice that can additional improve the realism of sunshine within the recreation: Ray-Traced Ambient Occlusion, with varied high quality ranges to select from.
Graphics Programmer Menno Bil explains: “Ambient occlusion is a method utilized in video games to simulate how ambient lighting impacts a scene. Ambient lighting is a type of oblique lighting: the sunshine mirrored from different surfaces. This impact largely seems at creases, cracks, and corners the place surfaces are shut to one another. Generally used AO methods are SSAO (Display screen Area Ambient Occlusion) and HBAO+ (Horizon-Primarily based Ambient Occlusion). These usually are not very demanding on the {hardware}, however they don’t present bodily correct outcomes. RTAO makes use of ray tracing additional to reinforce the realism of ambient occlusion within the recreation. We have now applied RTAO as an addition for these with high-end techniques with ray-tracing appropriate {hardware} and processing energy to spare.”
Menno and the crew additionally applied XeGTAO, Intel’s implementation of Floor-Fact Ambient Occlusion. Like SSAO and HBAO+, this resolution relies on display house. Subsequently, this system doesn’t allow the extent of realism that RTAO does, however the efficiency value is far decrease and akin to that of the HBAO+ implementation. XeGTAO is selectable as an possibility within the recreation and works with graphics playing cards from all distributors.
“XeGTAO generates a really high-resolution ambient occlusion that exhibits even the smallest particulars in geometry,” says Bil. “General, the output high quality of XeGTAO could be very excessive and leads to a nice look.”
System Necessities
Now that we’ve got detailed all of the options of Ratchet & Clank: Rift Aside for PC, it’s time to let you know extra concerning the system necessities. When making a PC model of a recreation, we put a number of work into scalability. Additions like ray-traced shadows, ray-traced ambient occlusion, and triple-screen assist are aimed toward these with the most recent and biggest {hardware} to allow them to push their techniques. With extremely customizable graphics and options, we make the sport scale to much less highly effective techniques to make it accessible for as many players as doable. Beneath is an outline of the advisable specs for quite a lot of graphical presets.
| Minimal | Beneficial | Excessive | Wonderful Ray Tracing | Final Ray Tracing | |
|---|---|---|---|---|---|
| Avg Efficiency | 720p @ 30 FPS | 1080p @ 60 FPS | 1440p @ 60 FPS (4K @ 30 FPS) | 1440p @ 60 FPS (4K @ 30 FPS) | 4K @ 60 FPS |
| Graphics Preset | Very Low | Medium | Excessive | Excessive Ray Tracing Excessive* |

| RAM | 8 GB | 16 GB | 16 GB | 16 GB | 32 GB |
| OS | Home windows 10 64-bit (model 1909 or increased) | Home windows 10 64-bit (model 1909 or increased) | Home windows 10 64-bit (model 1909 or increased) | Home windows 10 64-bit (model 1909 or increased) | Home windows 10 64-bit (model 1909 or increased) |
| Storage | 75 GB HDD house (SSD Beneficial) | 75 GB SSD house | 75 GB SSD house | 75 GB SSD house | 75 GB SSD house |
* Use of efficiency enhancing upscaling like NVIDIA DLSS is advisable when utilizing ray-traced reflections together with ray-traced shadows and/or ray-traced ambient occlusion

Whereas Ratchet & Clank: Rift Aside may be loved utilizing an HDD and the minimal system necessities, we encourage gamers to make use of an SSD together with the advisable system necessities or increased, to expertise the sport’s signature dimension-hopping gameplay as initially supposed.
