![]() In previous iterations of Civilization, it was possible to explore every option on the technology tree, and this made your decisions in research all about the order in which you discovered concepts, knowing that eventually you could learn them all anyway. Once again, the choices made by players will help shape their people’s identity, impacting cities and units aesthetically, as well as tying in with the all-new technology web. ![]() In Civilization: Beyond Earth, it appears that affinity took over this role, and is broken down into three categories – Harmony, Purity and Supremacy. These concepts helped align your nation with others that were like minded, as well as provide some bonuses as you unlocked more tenets. Players who had a chance to get their hands on the Brave New World expansion of Civilization V will remember the importance of Ideologies. For veterans of the franchise, this narrative is a complete turnaround from what they have come to expect of the series, although not at all unwelcome. Although a historical blackout prevents gamers from figuring out exactly what that is, it’s clear that humankind must leave earth and set out to re-establish themselves on other planets. Set approximately 250 years after present day, Civilization: Beyond Earth begins with players looking to the stars after events referred to as The Great Mistake. Following the hugely successful Civilization V, Beyond Earth aims to retain the core values that players have come to love, but also build on them with a fresh take on concepts such as the technology tree and ideologies. However, we believe the time is ripe for multi-GPU machines to provide a user experience just as good as single-GPU systems, and with the explicit multi-GPU control provided by AMD Mantle we have started working to make this a reality.Civilization: Beyond Earth is an upcoming turn based strategy game that is currently in development by Firaxis Games. Some machines (especially those with slower CPUs) may not see high performance gains, and the highest gains will be seen at higher resolutions. Our split-screen rendering probably won’t get the same frame rates as AFR techniques, and we are currently limited to 2 GPUs. ![]() “We do not claim to have the perfect multi-GPU solution with Civilization: Beyond Earth, and our current implementation has does have some limitations. Kloetzli concluded that multi-GPUs should start offering an experience similar to the one provided by Single GPUs, despite all the shortcomings that SFR introduces. However, the drawback here is that SFR is slower than AFR. Firaxis chose this mode due to the design of the Civilization rendering engine, and because this method does not bring micro-stuttering to the table. “Rather than trying to maximize frame rates while lowering quality, we asked ourselves a question: How fast can we get a dual-GPU solution without lowering quality at all? In order to answer this question, we implemented a split-screen (SFR) multi-GPU solution for the Mantle version of the game.”Īccording to Kloetzli, SFR breaks ‘ a single frame into multiple parts, one per GPU, and processes the parts in parallel, gathering them into the final image at the end of the frame. Therefore, Firaxis decided to use SFR (split frame rendering) in Sid Meier’s Civilization: Beyond Earth via Mantle. This means that AFR multi-GPU solutions have worse response time than a single GPU capable of similar frame rates.” ![]() ![]() The cost, however, is an extra frame of latency for each GPU past the first one. By alternating the GPU used each frame, rendering for a given frame can be overlapped with rendering of previous frames, resulting in higher overall frame rates. #Sid meiers civilization beyond earth demo driversWith the limited information available drivers are almost forced to implement AFR, or Alternate Frame Rendering, which is an approach where individual frames are rendered entirely on a single GPU. “Current multi-GPU solutions are implemented in the driver, without knowledge of, or help from, the game rendering engine. In addition, Firaxis has published a post explaining how the team approached multi-GPUs via Mantle in order to eliminate micro-stuttering and offer an experience similar to Single GPUs.Īs Firaxis’ John Kloetzli claimed, while AFR offers – most of the time – an amazing increase of the average framerate, it does come with some shortcomings. So, strategy fans, get ready for a treat as a demo for Sid Meier’s Civilization: Beyond Earth can be downloaded right now from Steam. In an age when video-game demos are on the verge of extinction, Firaxis and 2K Games decided to stand up and show to the public how gamers should be treated. ![]()
