Game introduction: Auto Chess* was jointly created by Dragonest Games, Giant Bird Studio, and IMBA Media, and is a competitive chess-type game. In the game, eight players start in different locations and earn gold from battles, and by grabbing the pieces in the shared card pool, which are used to match with and evolve their own pieces. As the army grows, the chess pieces automatically engage enemy pieces.
Graphics and game performance: The PC version of Auto Chess was created with Unreal Engine 4 and features a monstrous fantasy continent. The game is optimized for multicore and multithread Intel® Core™ processors and its performance has been upgraded on the latest Intel CPU platform. Currently, the game is still in the development stages, and the exclusive trailer for the beta version was displayed at the Intel booth, which attracted a lot of attention and questions from fans. Everyone is looking forward to this hit online PC game.
Figure 5. Player experiences Bright Memory.
Game introduction: Bright Memory is an action shooting game developed by FYQD-Studio and developed based on Unreal Engine* 4. The narrative of the game is presented in a linear process and is about the adventure of a supernatural science research team member, Shuya. Bright Memory is different from traditional FPS gameplay in that the game adds a motion combo mechanism to the shooting. Players can use different combo styles to use a set of gorgeous combos, and there is also a real-time scoring mechanism in the game.
Graphics and game performance: Thanks to the open source nature of Unreal Engine 4, FYQD-Studio was able to develop the game efficiently and at low cost. At the same time, with the addition of Intel technology, the quality of the game graphics was guaranteed, and users can play the game on most PC platforms with a smooth experience. Most of the art in the game was made using PBR (Physically-Based Rendering) , and by using Intel multicore and multithread technology for targeted optimization, the features of Unreal Engine 4 were fully utilized while the overall costs were also reduced.
The Intel® Game Dev Program Creates an Active Gaming Community
During this edition of UOD, Intel introduced the Intel® Game Dev Program via video promotion and live presentations. Not only will you get the most basic technical support through this program, but also achieve more market exposure opportunities. It also plays an important role in game design, game development, marketing, and other aspects.
The Intel Game Dev Program is designed to serve game developers at all levels, from indie game developers to large game studios, helping them to optimize game performance and enhance user experience. On one hand, Intel's technical team can help developers optimize game performance to get as many games as possible to run at 30 to 60 frames per second on the integrated graphics from Intel®, and to meet the basic needs of smooth gameplay. On the other hand, Intel supports game developers by utilizing hardware performance sufficiently, and providing powerful graphics adjustment options. As for smaller games with simple graphics, Intel platforms can sufficiently satisfy game performance requirements. For developers of games that require higher game performance and higher graphics performance, Intel also provides options for powerful multicore and multithreading processing. For example, better particle effects and physical damage effects can be achieved to realize better performance and user experience at the same time, which promotes the development of high-quality games.
By following the Intel Game Dev program, you can learn more about technical training and development tutorials, tools, and kits, or the development experience of other game development programs based on Intel platforms, learn how to better plan and design your own games, and receive better technical guidance and software and hardware tool support. The Intel Game Dev Program can also help game developers to fully explore or create multiple online and offline exposure opportunities, establish industry influence for game products, and focus on target customers, thus achieving both an increase in the quality and popularity of the game.
ISPC Reveals the Secret Behind Chaos
During UOD's technology sharing session, Jeff Rous, Intel senior engineer, along with two other Epic Games technicians gave a special presentation on Chaos. After the Epic Games engineers introduced the performance of Chaos, Jeff shared how Intel provided technical support during the design process, and how the single-program multi-data (SPMD) program compiler played an important role in Chaos. Making Chaos faster: a peek behind the curtain.
Figure 6. Jeff Rous gives a presentation.
Chaos is a real-time physical destruction system in the Unreal Engine. Compared to the existing toolset, Chaos can help users create more complex real-time destruction effects. In addition to making breaks inside the engine, there are dynamic strain assessments and next generation collisions.
- The C++ language used in the Chaos system does not perform well in single-instruction multiple data stream (SIMD) applications, but the integration of the ISPC enables the performance of the Chaos system to be improved by about three times in key areas.
- ISPC is a kernel-based SPMD programming language. It is compiled into a scalar code kernel with multiple instance combinations for SIMD or single instruction multiple thread (SIMT) vector computing architectures, enabling vectorized assembly code to be generated in a simple and efficient way.
- Developers can write ISPC once and compile it to a large number of vectorized instruction sets (such as Streaming SIMD Extensions 4 (SSE4), Intel® Advanced Vector Extensions (Intel® AVX), and Intel® Advanced Vector Extensions 2 (Intel® AVX2)). If the developer is compiling multiple instruction sets, there is an automatic detection mechanism that selects the correct function based on the user's CPU. When the new instruction set is used there is no need to update the internal functions, and it only needs to be recompiled.
- In the Chaos system, ISPC is suitable for intensive computational binding workloads such as physical cross-testing, fabric, or CPU vertex conversion. ISPC plays a particularly significant role when there is no data dependency between operations or when combined with the Parallel.For batch scheme.
