yes I work on The X a and can you run a business microsoft and i'm here to talk about performance the games on windows phone 7 series so performance starts with hardware and in the design of the hardware business phone we have the two sets of environments their overall overarching design Delta this button was to do the right thing in the end user and when we talk to end-users about what they want to see the phone device the thing we hear time and time again only one choice they want variety it was a number of option about sizes and colors or practices but the other thing users say is that they want a great selection of apps and games and to get those great action games we need you guys to go make when we talk to developers about what they want to see in a phone they say we do not want any choices at all because everyone to be exactly the same so that we don't have a reputation in the system so what we've done is we've built some consistency in to the hardware across different phones so the over the same processor the same top speed 70p unique abilities the one thing that can vary is the screen resolution at launch all photos are going to have an 800 x 480 resolution but later on we're going to be adding a second resolution 480 x 320 the good news here is that's just two resolutions it's not every possible slices great and we have a kind of land and exporting both of these resolutions really a little farther province anyone is that it's a balancing act there are three competing practiced at a love triangle you get to pick any two can't have all three if you want but at least you go up on the bigger ones has to go down to compensate the things that matter of what bravery what you getting to relax how many was it cost you to rather every mix-a-lot on the screen and how many of these pixels in planning a very sweet fragrance in lo the phone progress is busy lives 30 frames a second there's the PLC wasting time when the war ends of matter in the excellent breaker game Little Miss Kercher's when you said that the kind of target elapsed time you can set it where at lunch will call but leg factory service something aya but you're only been actually be able to draw graphics to the screen that says you can also set it lower in there are some games waitin you really don't need you want to draw simple lunch thing the second is good enough of your game design pixel cost important to understand is how much each item must meet the two things that really determined they sell what effectively using I just take another quick trip through the five attacks that you have to play with and share how they will announce that moves differently than affect performance be careful turning on extra lighting your whether you wore bones and using character always below decks anon is you're going to be a pixel cost if you can get results from changes in the lower left that's always going to be vaccinated and then the other thing that affects this is how many times to my draw page next year if i'ma story one that is that most games have it sky and for building and have another big mythology that building so you can end up doing the same pixel doesn't I'm hundred ninety that other name is a new come through the roof you get out of control so you need to watch the stuff there are many algorithms reducing over drill look at these other simple things like mystical things in a very far away use custom color use hierarchical illusion systems like the s in trees and a very simple level just sort all your object from front back from the close ones first and then the graphics card agreements to draw something further away very efficiently reject that not bother to correct a very useful tool to build into your head is an open door x-ray mode change all your every moment is known to drop in the texture turned off editing of the landing and set your colors and a duck ray if you do a scene using this every time the pixel gets quality will get brighter and you can look at the screen there's something white that mean you into a lot of times but we love changing your art work something out the Bible slider you have acknowledging these three factors is how many pixels you read them and this is what it do some things about the Sun hard way we have a one where scalable if you have a control over this choice the screen display currently is 800 x 480 that's what mother pixels the comparison the xbox one had twenty-five percent less pixels and this bonus doesn't awesome screen rendering tags browsing the web of singer chris candido very very nice for intensive 3d games Texas see my pic something a little lower different related requests for X instead most everyday 600 x 360 that's a neat half is my exes twice which program network rather a maximum resolution Robin Christmas but if you want rich to rename before external more layer the graphics you may need to reduce resolution doing this book in too many GQ it's literally critical piece of hardware that runs in parallel with everything else instead of damage to build up a casa it's a really nice high quality scale it's not as defined earlier example instant noodles with many packs the only thing that this building is he is extracted from the device screen resolution I talked about how they're going to be couple of different from normal women four factors with different sized screens you need to care about that you want to make a game that renders affected by for action do it you don't because the phone screen is smaller we'll use the scalar to shrink down buildings by and we'll update all in quite touching work to madness of it you will need to know that the screen size change like I didn't maybe 660 will scream let's look at the sched so here at having multiple system if you've seen these big before you're probably wondering why there are no cats in buy them they are my touch the screen indicates tax simple little particle system if I tell have this one right so I didn't automatically creates lots of gas which ended up going to the right it's going to create the ridiculous number attacks and you'll see the Frederick's part of the drop description too many labor and time all scream man in a little basic x 480 resolution too many cases so if I click here now it's running 360 x 600 feelings pretty much the same the Texas slightly blurry finish till same inputs the words between London to 40 my partner testes blurrier it again but not too bad see more blurry thing you guys have seen ever natural devices later it's it's pretty good attend the spawn right now this is a touch is still working even though I'm rendering a quarter resolution now when I touch cat still appear in the same list as I touched on the screen
