The introduction of Windows 8 made it possible for PC manufacturers to start building full-blown tablet PCs. These run Windows and have the same kind of hardware you'd usually find in a laptop. Some are on par with an ultrabook, and gaming peripheral company Razer sells a gaming tablet called the Edge.

This has made users curious about how far they can push the limits of a tablet PC. Can the system run games? And if it can, what are the common limitations? Here's everything you need to know about gaming on a Windows tablet.

The Hardware Question

Before delving too deeply into other aspects of gaming on a tablet, we should first address the hardware. If tablet PCs are too slow to run games, the rest is rather pointless, right?

Surprisingly, most Windows tablets can run modern games. Any model with a Core processor also comes with Intel HD 4000 graphics (or better), and while hardly a powerhouse, this integrated graphics solution can run all but the most demanding titles (like Battlefield 4 or Titanfall) at 1366x768 resolution and low to medium detail. Games like Diablo 3, League of Legends and Team Fortress 2 can be played at an acceptable framerate if you don't mind a somewhat ugly experience.

There are also a few tablets, like the Razer Edge, which feature discrete graphics. These can play any game at 1366x768 and low to medium detail, and older titles may be enjoyable at high or maximum settings. You pay for the privilege, though; the Edge starts at around $899 (on sale).

Some tablets don't use the more powerful Core architecture and instead use Intel's Atom. The older Atom single-core and dual-core parts have an ancient integrated graphics processor that's virtually useless for gaming. Newer quad-core models are quicker, but still not really up for running most titles at anything but the lowest detail available. You'll want a Core-powered tablet if you have any plans to game, even if only on occasion.

Touch-less

So, it turns out that tablets can run games. With that established, you may be wondering what cool new games you can play using a touchscreen device.

The answer is... none, really. Most games built for Windows don't support touch or, if they do, implement it in the most rudimentary fashion possible (Civilization V is a good example). Even Halo: Spartan Assault, which debuted on Windows 8 and Windows Phone 8, can be played with a keyboard and mouse.

You'll find a fair number of touchscreen games on the Windows Store, but the majority is ported from other platforms. You can enjoy hits like Jetpack Joyride and Cut The Rope if you haven't already played them on a smartphone or Android/iOS tablet, but don't expect anything unique.

In short, there are no notable titles built for Windows tablets, and you'll need a keyboard and mouse (or an Xbox controller) for most games.

What You'll Need For PC Tablet Gaming

At this point, I've probably convinced you a tablet PC isn't a good pick for gaming no matter the genre. That's good. Anyone buying a tablet to game is going to end up deeply disappointed.

But not everyone has a choice in the matter. Some people use Windows tablets because they're portable and easy to travel with, yet also want to play games, too. Here's what you should pack if you do intend to game on your tablet.

First, if your tablet does not have a stand, make sure that you find one. This will be necessary to prop it up on a desk and play a game. The Anker Mutli-Angle works well with thin tablets, while owners of thick tablets will need something like the IPAD-ST [Broken URL Removed] or the Cyber Acoustics Universal Tablet Stand.

Next, you'll need a controller. If you primarily play titles that are cross-platform, like shooters and role-playing games, the Xbox 360 controller is a great choice. Many developers optimize for the 360 controller and a wired model is only $20. I suggest going wired because you won't have to worry about packing batteries or a battery charger.

Many tablets have just one USB port, which will be occupied by the wired controller. That's a problem if you also want to use a keyboard and mouse. The solution is a USB hub that splits one port into three or four. Sabrent sells a cheap 4-port hub which does the job. Travelers limited on space may instead want Belkin's tiny 4-port hub instead.

Packing a keyboard specifically for gaming could be a chore, and at that point you might be better off with a gaming laptop. Still, there are options if you must game on a tablet. My favorite is the Cooler Master Quickfire Rapid, which lacks a numpad and as such is small enough to fit in almost any backpack or suitcase. You may want a mouse, too; I suggest the Logitech Wireless Anywhere MX, which has five buttons and an invisible laser than works on any smooth surface. Buyers on a budget might instead try the wired Etekcity, which is only $20 and also has five buttons.

Conclusion

Yes, you can play games on a Windows 8 tablet, and doing so isn't that difficult. The hardware and the operating system are identical to small laptop, so software and peripherals work as you'd expect.

I don't recommend buying a tablet specifically for gaming because there's nothing unique to play and the hardware isn't fast enough to run titles at high detail, but if you have no choice, you can make do.
