It was chosen by Luminous Productions because of its sharpness. ![]() It is extensively used in the Luminous Engine to downsample depth buffer for screen space reflections, color buffer, water refraction, and so on.įorspoken supports AMD's CACAO (Combined Adaptive Compute Ambient Occlusion). The SPD or Single Pass Downsampler offers a good performance improvement over multiple dispatches or draw calls, according to AMD. AMD FidelityFX Screen Space Reflections.The goal is to ensure the correctness of the implementation of the many AMD features available in Forspoken. The other half of the presentation was handled by Aurelien Serandour (Senior Developer Technology Engineer at AMD), who revealed that the collaboration between Luminous Productions and AMD began in July 2021. Still, even with these bottlenecks, the goal to attain a one-second loading time in Forspoken has been achieved in some scenes thanks to DirectStorage. Additionally, the future introduction of GPU decompression (such as the promised NVIDIA RTX IO) will be pivotal to reducing CPU processing and improving efficiency. Ono-san said that both need to be optimized more than ever to further improve loading times. Analyzing the Forspoken data, Luminous Productions noticed that the new bottlenecks are decompression and asset initialization. The reason is that file I/O speed is no longer a bottleneck for loading times with DirectStorage. However, in the actual loading time of a game scene from Forspoken, the SATA SSD demonstrates a larger improvement (0.8 seconds vs 0.2 seconds) than the NVMe M.2 SSD.įorspoken PEGI Rating Reveals Some Dark Story Elements By comparison, the file I/O speed of a SATA SSD is only marginally improved. The API is also optimized for asynchronous streaming data transfers of file chunks from NVMe M.2 SSDs with low GPU overhead.Īs showcased below, DirectStorage unlocks the file I/O speed of an NVMe M.2 SSD, which is nearly doubled compared to the Win32 API. With DirectStorage, multiple queues (such as loading and decompression) can be created and executed in parallel, and multiple read requests can be synchronized at once. While NVME M.2 SSDs can already improve loading times in existing PC games, DirectStorage can truly leverage their hardware potential, as evidenced in the below slide. The stated goal for Forspoken is to reach the astoundingly low loading time of one second on NVMe M.2 SSDs capable of over 5000MB/sec speed. Yesterday, Luminous Productions (Final Fantasy XV) have showcased the cutting-edge technologies they're implementing for their next game Forspoken, starting with Microsoft's DirectStorage API ( available now as a public SDK release).ĭuring a GDC 2022 presentation titled Breaking Down the World of Athia: The Technologies of Forspoken, Technical Director of Luminous Engine project Teppei Ono discussed the world-first implementation of DirectStorage in a PC game.ĪMD Radeon RX 6000 Raise the Game Bundle Adds Forspoken
