Console gaming (XBOX, Playstation, Nintendo, etc) or PC gaming.
Nathan is a gamer and wants to get a high end laptop. The games he likes to play are flight simulators. Leo says that a good choice may be a Windows 8 Touch laptop. The Asus Zenbook is a gorgeous Ultra Light. But Alienware makes laptops specifically for gaming. Another great gaming company is Falcon Northwest.
Don has the DOS based Duke Nukem 3D and wants to run it on his Windows 7 machine. Leo suggests downloading the free DOSbox at DOSbox.com. This is a DOS emulator that will run any DOS program right within Windows.
Leo would first check to be sure that his parents haven't downgraded to cheaper internet. If it's fast enough when connected with ethernet cable, then there's something wrong with the router. Unless he's far away from the router. One of the problems with WiFi is that less than strong signal does lower the speed.
Casey loves gaming, but consoles are slow behind the times. Leo says that console games have stagnated over the last 10 years, while PCs have leapfrogged into better graphics and faster processors.
Casey uses his PC for gaming, but he's getting a lot of lag. He's wondering if upgrading his graphics card would improve the performance. Leo says he could upgrade the graphics, but if his CPU isn't fast enough, it will still perform slow. They really work together.
Leo thinks the Minecraft.jar is obfuscated or further encrypted, so he can't get into it. He wants to install modifiers for his Minecraft game. Chad of OMGCraft says that's not the way he'd want to go about it though. Chad says to use MCPatcher, which will patch the mods he wants into the Minecraft JAR files. This program will let him install his mods without having to do any coding by hand.
Leo says it's possible that the graphics card could be slowly working itself out of the slot causing him to have to reseat it, but then it would just stop working altogether. Leo thinks it's more likely overheating, but Christian doesn't believe that's the case and thinks it's the motherboard instead. Since Asus made the motherboard, Leo advises running the Asus PC Diagnostics. He also should try updating the firmware.
Mike has an older PC game, Motocross Madness 2. Leo says that if it worked on an older version of Windows, chances are it will work under Windows 7 too. Microsoft tries really hard to be backwards compatible with every program ever written for Windows. Games are the most challenging, however.
Mike's main problem is that the game doesn't allow him to change which video card it uses. Because the game is older, it probably won't be possible to select the newer card because it wasn't available at the time the game was written. This is a hardware restriction, not a Windows 7 issue.
