in april, samsung galaxy gamedev went to croatia for reboot develop blue. we sent two technical staff and an account manager for a whole host of activities, and i’ll admit that we looked at the event (which is new to us) as a rather speculative attempt to connect with game developers. after all, reboot previously had no technical track and has only been running for a handful of years; maybe it would turn out to be a non-event. but reboot managed to exceed all our expectations. we had approximately 60 seriously-interesting and highly-competent game developers in our sessions. alon or bach, who heads our vulkan standards effort, did a great job in a talk on advanced vulkan programming techniques, which are used in croteam’s serious engine for mobile. alon then went on to host a panel discussion on the merits of vulkan. this panel featured some lively and informative input from karlo jež from croteam, christian forfang from arm, and graham wihlidal from ea’s seed group. quiz time! watch the above video of alon presenting at reboot, then answer the following multiple-choice questions (scroll to the end of the blog the answers). 1. what is the most significant performance gain you can reasonably expect to see when you completely fix some badly-chosen pipeline barriers in a trivial vulkan app? a. 25% b. 50% c. 100% d. nothing, there’s no such thing as a badly-chosen pipeline barrier. 2. in general, what’s the preferred draw order for opaque geometry in vulkan? a. left to right b. right to left c. top to bottom d. bottom to top e. front to back f. back to front g. some other order that isn’t listed here. 3. in terms of texture formats, why is a “tiled” buffer generally preferred to a “linear” buffer? a. samsung’s tiling architectures store tiled buffers on chip. b. reducing power consumption is more important for mobile devices than protecting bandwidth. c. there’s a bug in the driver. d. ha! it’s a trick question! tiling isn’t preferred. e. texture fetches cooperate better with the cache that way. 4. to make sure you were paying attention -- and for two special bonus points -- what animal did alon reference in his talk, and why? on the account management side, david pither spent most of his meal and coffee breaks over the three days having enlightening conversations with both developers and publishers who might benefit from collaborating with samsung’s galaxy gamedev group. it was business networking at its best, and we came back with a long list of action items which has kept david busy for weeks. david also set up conversations with folks that we regularly work with like sega, croteam, and ea. it’s always good to keep in touch with the big boys of gaming. we now know more about their technology and publishing roadmaps, which means we now know more about how we can help. my trip home was a bit of a disappointment. getting home roughly 15 hours late isn’t high on my list of “fun ways to start a holiday,” but it certainly won’t stop me (and more importantly) samsung from going back next year. in fact, my enthusiasm levels for the reboot events are so high that we plan to attend the reboot develop red event in banff in october. and of course, we’ll be back in croatia next spring. hopefully, we’ll see you there as well! reboot blue, and reboot red – they’re both firmly in our calendar from here on. soon we’re going reboot purple. we’re adding a lot more technical info over the coming months, so make sure you revisit the blog soon to learn more about vulkan. in the meantime, to keep you going: a gentle intro: vulkan-tutorial.com/introduction a set of beginner's guides: khronos.org/blog/beginners-guide-to-vulkan getting in deep: khronos.org/developers/library/2019-vulkanised-is-back (.pdf format) youtube.com/user/khronosgroup (videos) jet set vulkan : reflecting on the move to vulkan quiz answers 1: c 2: e 3: e 4: a hedgehog – because alon’s fellow speaker’s name is “karlo jež” and jež is croatian for hedgehog!

last week’s game developers conference in san francisco brought together top gaming professionals from around the world to showcase the latest in gaming technology. samsung participated in seven sessions during the conference showcasing the work we’re doing to advance the state of mobile gaming. you can re-watch select gdc sessions via our youtube channel. samsung is proud to be a promoter member of the khronos group and participate in many of their open standards, including the vulkan api. during #khronosdevday on tuesday, lewis gordon talked through depth stencil resolve, an upcoming extension to the vulkan api. kostiantyn drabeniuk then joined jack porter from epic games to discuss how we partnered to bring fortnite to mobile devices that run android 8.0 or higher (oreo or pie) and that have the right hardware can take advantage of the vulkan render hardware interface for higher performance than just using open gl es. you can get all of the presentations from the khronos dev day on their web site. on wednesday, samsung, arm, and epic games continued the discussion on optimization. i got my start building profiling and other real-time analysis tools for embedded systems, so i’m really excited to see all of these great tools being made available for today’s game developers. jose and michael shared practical tips on how to double your frame rate in one instance and how to get more than a 50% increase in performance by changing a single line of code in another. arm has also released their vulkan best practices for mobile developers on github. we also had a chance to share our work with unity on their upcoming adaptive performance feature. with precise information on thermal trends, mobile game developers can deliver longer play times and smoother frame rates on the galaxy s10 and galaxy fold. adaptive performance will soon be available as a preview in release 2019.1. we also shared the stage with google to talk about optimizing your apps for different screen sizes including dex and galaxy fold. if you haven’t already done so, check out our resources including our guide to app continuity, our emulator, and the remote testing lab. the google and sdp teams at #gdc19 finally, we discussed several aspects of our galaxy gamedev program which kicked off in 2016. samsung works with gpu manufacturers like arm mali, game engine providers like unity and unreal, as well as developers to ensure galaxy is the best mobile gaming platform. from loaner devices, tools, and on-site support, we’re supporting game developers around the world. we’ve introduced gpuwatch, which lets you monitor the performance of your game in real time without installing any additional software on the device. gpuwatch will be available through the developer options on select devices running android pie. our gamesdk, which will be available soon, allows you to check for gpu bottlenecks and predict thermal throttling so you can make adjustments in real time for maximum performance. outside of gdc, i had the opportunity to attend the 19th annual women in gaming rally. with a focus on diversity and inclusion, the panel discussion at this event highlighted some of the great efforts being made to ensure game creating and game playing can be great experiences for everyone. the energy and positivity in the room were truly inspiring. we hope you’ve enjoyed our focus on gaming during the month of march. stay tuned to our blog for #gamedev news.
