Citind stirea primul gand care mi-a trecut prin minte a fost: "Wow...just...wow!" Acum sincer probabil ca si voi restul cititorilor intrand pe ConsoleGames.ro si vazand acest titlu de articol v-ati gandit "WTF! Despre ce e vorba? Cum adica Battlefield pe iOS din moment ce jocul a avut probleme cu cerintele de sistem si pe PC?". Ei, dragii mosului sa o luam usor si sa va povestesc ca echipa din spatele motorului grafic Frostbite care motorizeaza jocurile din ultima perioada produse de cam toate studiourile gigantului EA GAMES (Need for Speed Rivals, Battlefield 4, Dragon Age, etc...) pe PC si console a avut marea sarcina de a porta motorul grafic pe mobile. Si nu numai ca a reusit dar a si prezentat la eventul Apple un tech demo al jocului Plants vs. Zombies: Garden Warfare ruland pe un iPad Air! Thats just sick dude, 1.3 milioane de triunghiuri pe ecran simultan ca sa arate de ce este capabil motorul grafic! Urmatorul pas? Portarea jocului Battlefield 4 pe iOS.
Kristoffer Benjaminsson, Product Owner Mobile in cadrul Frostbite ne povesteste:In urma cu un an mai multi membrii ConsoleGames.ro aveau o discutie in care luau in calcul smartphonurile si tabletele ca si device-uri de gaming/console portabile. In ultima perioada luand in calcul stirile de acest gen precum si ultimele aparitii in materie de hardware (nVidia K1, Nexus Player, etc) incepem sa vedem tot mai mult ca device-uri de gaming platformele mobile.It has been quite a challenge. To handle dynamic features such as destruction or moving light sources, most things in the Frostbite engine happen in realtime. This puts extra demand on performance to be able to deliver large, highly detailed worlds with superb visual quality. We were making great progress feature-wise, but hardware and software limitations forced us to either scale down the number of objects and their complexity to retain visual fidelity, or accept lower visual fidelity to cope with a larger number of objects.
This all changed when Apple introduced Metal, their new low-level graphics API, which allowed us to make full use of the hardware. Together with the latest range of hardware, Metal has created possibilities previously out of reach and for the first time we can include both high visual fidelity and a large number of objects.

So to see exactly how far we could take the engine on mobile we set ourselves up for a real challenge: getting selected parts of the Battlefield 4 – truly a visually demanding game – running on iOS! I want to stress that this has been a tech demo to test the engine capabilities, and nothing else.
There is still much to do, but we’re very happy with the results so far. It’s a great feeling porting a system, get it running, and discover that there’s actually performance left. Even though we have much room for performance improvements on our end, we’re pleasantly surprised of the performance we’re getting from the hardware.
We’ll wait for future posts to dig into more details about this, but we are ready to share some screenshots of our work in progress. We hope you find them as exciting as we do.
Until next time!
