    Yeah, my devkit makes that noise, it's been quietly driving me insane... Reply 0
  • The Crew won't release on PS3 and Wii U due to different "technical infrastructure"

  • andrewchappell 15/08/2014

    @PirateRoberts Nope, if you're writing a new engine you're doing so without planning for SPUs. They were a massive headache - sure I'd imagine ubi have libraries of SPU code that they can use, but the architecture of your entire engine has to be PS3 friendly if you want to get decent performance out of it. And if you've written a new one then it makes no sense to include PS3 support at the detriment to other platforms. Reply +2

    @ShiftyGeezer Decent vector math code runs better on Jaguar chips as well - in fact modern compilers will be moving as much floating point code as possible into SSE / AVX instructions. A decent vector math library will (well, should) be the staple starting point of any engine.

    Trust me on this. It's my job to do this stuff - we're currently building a (recently announced) Xbox One / 360 game, and the things you are talking about regarding CPU aren't an issue. Sure, porting is plenty hard - but cpu performance is the least of your worries...

    @ShiftyGeezer Don't underestimate the power of the high clock rate PPC chips in the 360 and PS3. And it isn't that difficult to get good performance out of them. In fact, with decent vector math code they can comfortably outperform the crappy jaguar chips in the next gen consoles.

    Edit: And your porting "scale" is way off. It's not going to be trivial to get a next gen game running well on 360, but it's far easier than PS3 if you don't have an existing SPU ready codebase to work from. PS3 would be the most difficult port at, let's say, 10. WiiU probably comes in at about a 6 or 7, and Xbox 360 a 4 or 5. Seriously, nobody likes writing SPU code...

    @wyp100 Each individual release would have to go through cert (this is the same for both console platforms) - the cost of pressing different discs is insignificant compared to this. Reply +1
  • Frostbite engine in the works for mobile

  • andrewchappell 15/05/2013

    @StooMonster No way it's running at 3.24ghz. The power draw + heat dissipation from such a change would be crazy. Also that article keeps mentioning power6, when the WiiU CPU is based on a much older architecture.

    And yes, there are differences between the WiiU and 360 - you can't just compare clock rates. But there's no point arguing the primary point - the 360 CPU is a more modern (in terms of features) and more powerful cpu than the one found in the WiiU. The architecture for this chip was dead with the Wii, it's now got to the zombie stage with the WiiU...

    @StooMonster These are all non-issues when porting an engine. The WiiU CPU is just slow and old :( Reply +2

    Don't underestimate how rubbish the WiiU CPU is. Mobile processors are more than competitive with it. Couple that with proper vector unit support (seriously, what were Nintendo thinking?!) and yeah I can see any decent engine being easier to port to mobile than to WiiU. Sure it can be done, but it won't run particularly well and will require a large investment in terms of programming time for a market which just isn't there. Reply +1

  • Layoffs at Elite: Dangerous developer Frontier

  • andrewchappell 17/12/2012

    Just something to mention - I *was* a Software engineer at Frontier until I left (to try something new - not due to any layoffs or anything like that) about a month ago. So ex-Frontier software engineer rather than current. Still sorry to see good people lose their jobs though :-( Reply +12

    @vizzini It has no association with Watson, and has fewer hardware threads than the 360. Reply 0
