:
Introduction to Call of Duty Black Ops 6
- The video discusses the enhancements of Call of Duty Black Ops 6, which is released just before the PlayStation 5 Pro hardware launch.
- The video features insights from Mikal Drobot, the principal rendering engineer, and the team at Infinity Ward Poland, providing a behind-the-scenes look at the game development.
- The focus includes the technical upgrades for PS5 Pro and significant engine changes for the game.
PS5 Pro Support and Upgrades
- The PS5 Pro update for Black Ops 6 has been available for about a month, offering deeper upgrades compared to previous versions.
- Players using PS5 Pro experience improved visual settings while maintaining a frame rate of 60 frames per second.
- The adoption of PlayStation Spectral Super Resolution (PSSR) enhances image quality at 4K, alongside an anti-aliasing variable refresh rate (VRR) feature that allows frame rates above 60 FPS.
- The performance boost is notable when enabling the 120 Hz mode, reverting to base PS5 visual settings to achieve higher frame rates.
Visual Enhancements to Pro in Default 60 FPS Mode
- The default 60 FPS mode on PS5 Pro features four key visual improvements, starting with a 2 to 4 times increase in shadow resolution based on shadow type and distance.
- Improved global illumination is introduced with a screen space global illumination (SSGI) method that simulates light bouncing between surfaces, enhancing realism in lighting effects.
- Upgraded screen space ambient occlusion (SSAO) adds more detailed ambient shading, creating a more lifelike final frame in various scenes.
- The final upgrade involves improved screen space reflections, which aim to match the internal path tracing reference, enhancing the accuracy of reflections in the game environment.
PSSR and Its Performance
- PSSR operates only in the default 60 FPS mode, running internally at 2560 x 1440 and upscaling to 4K, with dynamic resolution adjustments to maintain stable frame rates.
- While PSSR delivers a clean image, it can cause artifacts, such as white flickering in dark areas, due to not being fully optimized for denoising.
- The team is aware of these issues and is working on a fix, as the current TAA method remains advantageous for denoising and performance (BO6's TAA method costs less than the 2.1ms required for PSSR).
- PSSR also smears fine details compared to the sharper presentation of the traditional TAA method used on PS5.
- Variable rate shading (VRS) was integrated just before the game's release, helping to optimize performance by rendering pixels at varying resolutions based on their importance in the scene. For every group of pixels the game can render at full, 1/2, 1/3 or even 1/4 resolution.
- Also a form of foveated rendering like used in VR headsets is in place too which puts a priority on rendering better details towards the centre of the screen while there is a falloff in quality moving out towards the edges of the screen.
Frame Rate Testing on PS5 Pro
- Testing shows that Black Ops 6 maintains a consistent 60 FPS on PS5 Pro, even with the visual upgrades and demanding PSSR upscale.
- In split-screen mode, the performance drops significantly on base PS5, while PS5 Pro manages to stay near the 60 FPS line with minimal frame drops.
- The PS5 Pro also features an anti-lag VRR technology that allows frames to be rendered faster, improving responsiveness compared to traditional VRR implementations. This tech was made in conjunction with Sony. This VRR tech only works in 60hz mode.
- The anti-lag VRR mode works by predicting frame times, allowing for quicker frame generation and reduced latency between input and display.
Switching to 120 Hz Mode
- Switching to 120 Hz mode disables the visual upgrades and operates at 1440p internally, using the in-house TAA for graphics quality.
- Performance improvements of up to 35% are noted, with many scenarios running at or near 120 FPS, although drops to 100 FPS can still occur.
New Engine Features in Black Ops 6
- The video highlights new engine features being introduced in Black Ops 6, demonstrated in a controlled test environment at Infinity Ward Poland.
- One notable addition is weather grade volumes (WGVs), which allow various environmental effects, such as mud and snow, to realistically affect player characters.
- The terrain handling system is enhanced, featuring virtual texturing that generates detailed texture maps based on player proximity and view.
- Grass rendering is optimized to ensure competitive fairness across platforms, with careful management of grass density and draw distances.
- Deformable terrain is also utilized, allowing players to leave realistic trails in snow and grass, enhancing immersion in campaign modes.
- Advanced glass simulation is implemented, allowing glass panes to fracture and break realistically in response to in-game actions.
Conclusion and Future Prospects
- The video concludes by emphasizing the numerous technical advancements in Black Ops 6, which build on previous titles and introduce new features made possible by the PS5 Pro.
- The improvements in visual fidelity, performance, and realism reflect years of development and innovation within the series.
