Can You Game on a MacBook

Hey guys this is Austin. Usually the words Mac and gaming don't go in the same sentence but is it possible If you want a gaming computer a Mac shouldn't be your first choice but what I want to know is can you game at all on a MacBook Take a look at the specs of this 2015 13 inch MacBook Pro and it's got a decent Core i7 CPU but the integrated Iris 6100 graphics aren't exactly made for hardcore gaming. Last year I tried a few games on a.

Mac Pro with much better specs and it did reasonably well but how will the MacBook stack up The first problem is just finding games that work on OS X. There are a few titles in Origin and in the Mac App Store but your choices are pretty limited. Luckily Steam is also available and here there's a pretty decent selection with quite a few games from my library that will work on Mac. First we have Borderlands The PreSequel. Here it's totally playable on low at 720p on the MacBook and just like on SteamOS The PreSequel is.

A solid port that's basically identical to the Windows version. Move over to Tomb Raider and it's not quite so nice. It's almost playable at 720p but we're getting pretty significant frame rate drops. Jump over to Metro Last Light Redux and things are a bit smoother but we're still dealing with the occasional choppiness during the more intense scenes. Things aren't off to a great start but how does the MacBook handle less hardcore games Minecraft is a staple of basically every gaming platform on the planet and the Mac is no exception. Performance is just fine even at 1080p as long as you.

Notch the render distance back a bit. League of Legends is the same story, this is a rock solid version of the game for Mac that runs no problem on max at 1080p. So a MacBook can handle mainstream games fairly well but next I wanted to see what we could do running Windows. Using Boot Camp I loaded a preview copy of Windows 10 which opens a much bigger library of PC games. Trying Tomb Raider again it's clear that Windows makes a big difference. We're seeing much more playable frame rates even with the graphics bumped up to medium.

Which got me curious, how much of a difference is there I ran the builtin benchmark on medium at 720p and the Windows performance was over double what it was on OS X, averaging 43 frames per second compared to just shy of 20 running Yosemite. For a laptop with integrated graphics this isn't half bad but let's try a couple newer, more demanding titles. Load up Grand Theft Auto 5 and it's totally playable on low at 720p.well as long as you have a mouse anyway. The only problem was a weird texture issue that made.

Some things semitransparent but this seems more like a GTA problem than the MacBook's fault. Shadow of Mordor is another great looking game and here we're able to get decent frame rates on low, nothing to blow you away but it's entirely usable. If you want to play more casual games a MacBook is fine but for demanding titles it might not be a bad idea to install Windows via Boot Camp, it'll give you way more options and things should run a fair bit better. The addition of Metal to OS X El Capitan should improve gaming performance.

Progression of wet AgeRelated Macular Degeneration

Welcome to the AMD Resource Center, presented by the Angiogenesis Foundation. This animation will explain how wet AMD causes vision loss. AgeRelated Macular Degeneration AMD is a disease that causes progressive damage to the macula, a central region of the retina. The retina is the light receiving nerve layer located in the back of the eye. 00027.000,000'.000 The macula contains the densest population of nerve cells, called photoreceptors, and is particularly important for seeing detail and maintaining the central part of our vision. Central vision is important for ordinary daily activities like reading, driving, dialing the telephone, and recognizing faces.

The macula is composed of several layers of specialized cells. The photoreceptors sit atop a layer of cells called retinal epithelial cells RPE. Underneath these layers is a thin lining called Bruch's membrane. Beneath Bruch's membrane is the choroid, a network of blood vessels that provide oxygen and nutrients to the macula. As the eye ages, debris from the RPE cell layer, and surrounding tissues accumulates above and within the Bruch's membrane. The debris form deposits called drusen. The presence of drusen is usually the first sign of early dry AMD.

As drusen accumulate, they can cause inflammation. Inflammatory cells are then recruited to the retina, and these cells, along with the RPE, begin releasing growth factors that cause blood vessels to grow. The primary growth factor released is called vascular endothelial growth factor VEGF. The VEGF protein diffuses into the choroid, stimulating the growth of new blood vessels. This process is called angiogenesis. The new blood vessels sprout and grow into and through the weakened Bruch's membrane. At this point, the condition progresses from dry AMD to a more serious form called wet AMD.

These growing blood vessels are abnormally leaky, which allows fluid and blood to seep into the layers of the macula. Fluid accumulates between Bruch's membrane and the layer of photoreceptors, damaging the delicate nerves required for vision. If left untreated, bleeding due to this condition can cause scarring of the macula and permanent vision loss. In the photos shown here, the first represents normal vision, while the second shows the effects of wet AMD. The most severe form of wet AMD causes central vision loss and can make daily tasks such as reading, driving, and recognizing faces impossible.

Animation Detecting agerelated macular degeneration through a dilated eye exam.

The Comprehensive Dilated Eye Exam Opening the Door to Preventing Blindness A doctor can detect signs of agerelated macular degeneration, also known as AMD, during a comprehensive dilated eye exam. The patient receives special eye drops that dilate the pupils. The pupils open wide allowing the doctor to see the back of the eye clearly. When eyes are dilated, the doctor can clearly see the retina, optic nerve and the macula. While examining the retina, he or she can look for signs of AMD. If this patient had AMD, the doctor would see yellow spots beneath the retina.

Called drusen or dark clumps of pigment. AMD is the main cause of visual impairment and blindness in older americans. Dilation enables doctors to get a better view of the back of the eye which allows them to determine whether there are early symptoms of disease. But it's important to know that all people older than 60 need a comprehensive dilated eye exam each year and should inform their doctor right away if they begin to have problems with their site. People at higher risk may need to have a dilated eye exam more often.
