cheap jordans 11 for sale : Space Pirate TrainerDo you remember playing Galaga Space Pirate Trainer is a VR game that puts you into an arcade shooter, except as you might have guessed, gameplay is a bit more involved. Today results reflect exactly that, real world gameplay. cheap jordans 11 for sale

cheap jordans in stores As you play Space Pirate Trainer you are contained to cheap jordans shoes your room scale area inside the game as well. You are on a circular shaped platform that projects from the side of some sort of space station above a planets surface. As you stand inside the play area, your opponents move up from below the platform to make themselves visible and start their attack. These attack drones zoom all cheap jordans online around to mount their cheap jordans free shipping offensive. Their range side to side is about 180 degrees, so you will find them sneaking up on your blind side as well. The drones shoot laser blasts at you. As the blasts get closer to you, and you are in danger of getting hit, the game goes into a Max Payne esque bullet time mode to give you a chance to save your skin. You get three “lives.” As you clear out the full field of drones, you move cheap adidas onto the next level. As the cheap jordans cheap jordans sale in china levels progress, the combat gets more involved and harder to win. cheap jordans in stores

cheap jordans online mens As you probably realize, it is near impossible to get two gaming runthroughs that are “the same.” As I played through I found that GPU Render Times on our cards tended to not deviate more than 15 hundredths (0.15) of a millisecond on runs that lasted the same duration across the same levels. Our duration that I settled on is 5.5 levels of gameplay that lasts around 4 to 5 minutes each for each runthrough. The first 10 levels of SPT are fairly tame in terms of GPU intensity. Our runthrough data represents playing levels 10 through 15 of SPT successfully with us giving up the ghost in level 16. If we had runthroughs that we experienced to be very different in terms of time duration or events during those runthroughs, cheap Air max shoes we retested. Actually, I retested a lot to get runthroughs I felt were solid in terms of comparability across video cards. cheap jordans online mens

cheap authentic jordan shoes I used the same cheap nike shoes guns for our runthrough, dual pulse laser pistols, never changing. I also never used the available shield either. There are also available power ups, that I had decided not to use at first, but not accidentally activating those became almost impossible. I decided to go ahead and use those during the gameplay. Again, testing with those did not hugely impact our data as long cheap yeezys as we covered at least 5 levels of gameplay. I will say that it cheap jordan sneakers really sucks to stop and do data cheap jordans china collection when you are in a groove too. cheap authentic jordan shoes

cheap air jordan shoes free shipping You have likely heard this already. VR headsets, and I will be talking particularly about Vive technology here, although Rift does the “same thing” when looking at the big picture, all run at 90 frames per second. Your first thought is probably, “Why This simple answer is that if they do not run at 90fps, you will get motion sickness, and blow chunks. Seriously. But why would you not just run at 89fps instead of dropping to 45fps Good question. The answer is tearing. Tearing frames is totally unacceptable in a VR game, whereas we may put up with it without consequence on the desktop. So there are some “V sync” things at work with these new head mounted displays that leaves us with 90fps, cheap jordans on sale or 45fps if the hardware can keep up, and 45fps leaves you with lunch on your shoes, so something had www.cheapjordanssvip.com to be done. cheap air jordan shoes free shipping

cheap exclusive jordans Both Vive and Rift have technologies to combat the dreaded 45fps. (I have been told by several people that if you get drunk before you play, that 45fps is a lot more acceptable to users, but I have not tried this. Please send me mail.) Rift is Timewarp, and Vive is Reprojection. For the use of this article we are going to call these technologies the “same,” however these are not. But they do solve the same common problem in much the same manner. cheap exclusive jordans

cheap jordans website legit When your Vive is not able to keep a 90fps pace while you are playing a VR game, cheap jordans from china Reprojection technology kicks in and tells your hardware to render at 45fps and let Steam VR tech fill in every other frame. Pretty slick eh So in effect, your eyes are still seeing 90fps and therefore you should not vomit on your shoes. The caveat is that Reprojection technologies do have some drawbacks as artifacting can be present in your game. I think Reprojection for the Vive is likely to be a game to game thing. Remember how I said cheap jordans for sale “Reprojection technologies” just above there That is because there are several ways of doing Reprojection, so your mileage may vary from game to game. Today we are talking about Raw cheap air jordan Data and overall, I could tell the game was a lot snappier when my Vive was not in Reprojection, but honestly, I could play for long periods of time with it in Reprojection and it did not bother me. cheap jordans website legit

cheap jordans 9.5 In our graphing, and I will remind you of this as we move along, when you see the red line at 1, that mean NO Reprojection is happening. When you see the red line at 2, that means that the system is using Reprojection. You could say Reprojection is “bad,” but it is certainly not as bad as 45fps. Trust me. We will call Reprojection “not ideal” instead of give it a bad rap as it is surely there to help us out. cheap jordans 9.5

cheap jordans 4 On our graphs you will also see a yellow line, this tells you how many dropped frames there were. There will be some argument about how this is cheap jordans sale shown, because when I show you 200 dropped frame across an X axis that has 50,000 data points on it, we simply cannot draw the lines small enough to actually represent how small of an event this really is. So on some graphs, you will see a lot of yellow and think, “holy crap, this GPU was sucking bad” when it comes to rendering VR frames. Well, the way it is graphed can make it look much, much, much worse than it is. This is why we give you the actual number of frames dropped along with how many actual frames that were drawn. And of course we will discuss that as well. cheap jordans 4

cheap jordans 6.5 We have saved the best for last and that is GPU Render Time shown in milliseconds. Since we know that our hardware has to render frames at either 45fps, but hopefully 90fps, how do we really measure what the hell is going on with our GPU. We have examined this from a few ways, and the VR purist will probably tell you that the VR experience must not allow the system to go into Reprojection mode with the Vive, or Timewarp with the Rift. And that would probably be correct, but the fact of the matter is that is simply not going to happen at this early stage in the VR game, if ever. The person a step down from that would probably tell you that Reprojection, with minimal dropped frames is acceptable from an experience point of view. I am probably in this group right now. The next person down the stack would likely tell you, “Turn off Reprojection/Timewarp and ride it out like nature intended.” That person is likely not the one you want to listen to in my experience. Seriously, different folks react to these technologies differently, so there is not telling what you might find acceptable gameplay. The only way to do that is to figure it out for yourself. cheap jordans 6.5

cheap jordans real shoes At 90 frames per second your GPU must render a new frame every 11.1 milliseconds. You will see our graphing has hash lines at 5.55ms, 11.1ms, up to 22.2ms. If the GPU takes more than 11.1ms for a couple of concurrent frames, it turns on Reprojection like we talked about above. If you do not have Reprojection turned on, it will Cheap jordans cut your display rendering to 45Hz, since frame tearing is totally unacceptable (I have never seen tearing on a VR headset, but I just guess it is horrible.), then you puke. cheap jordans real shoes

cheap jordans under 40 dollars But really 11.1ms is not the real number either. Once the Vive hardware and Steam VR software see that you are getting close to busting 90% of 11.1ms, the software starts having the hardware make changes. My explanations here have already gotten too long, but there are 1000s of pages of documentation that you can wade through to figure out for yourself online that will very likely put a lot of things about VR into perspective. I would highly suggest watching this lecture given by Alex Vlachos of Valve on Advanced VR Rendering Performance as it will give you a lot of insight as to what we have discussed here if you need more information cheap jordans under 40 dollars.
