A glance at the table will corroborate what other benchmark comparisons (see More Coverage below) have already shown: Windows 8 doesn't currently do much for gaming other than preserving it. If we ignore PCMark 7 for now, which currently comes with a health warning, then gaming-relevant performance is broadly even. Personally, I just carried on running my existing Steam games as normal, and I was pleased that my hardware -- including an ASUS Xonar sound card and Xbox 360 wired controller -- was recognized without issue. But few people will spend money on an upgrade merely to experience what they already had with Windows 7.
Of course, there was that whole Gabe Newell "catastrophe" saga recently, and it had little to do with hardware issues. The Steam founder was mainly worried about the new Windows Store potentially becoming the only way for Windows users to buy and install new games. Politics aside (at least for now), I did explore the Store and a couple of game demos, but I lost interest pretty quickly. For the time being, Microsoft is putting the emphasis on tablet games and cross-compatibility with ARM-based RT tablets, with the result that the selection of games for desktop users is limited and often inappropriate (Fruit Ninja, anyone?). When I'd finally confirmed that it's possible to have a launch-day roster of 40 Xbox Live games and yet not include classics like Fez, Braid or Super Meatboy on that list, I made a polite exit.

Anyway, returning to the table, the more general indicators of performance show some significant gains as a result of the upgrade -- gains which do seem to make the system snappier when it comes to racking up a game. The FastBoot feature we've seen on some recent Windows 8 laptops was never going to work with my particular motherboard and graphics card, but the wake-up and sleep times were both significantly reduced -- and since I hardly ever switch my PC off, those two measures are more useful to me. ATTO showed a 10 percent gain in storage read and write speeds, running on a 750GB Seagate Momentus XT hybrid drive. Internet Explorer 10 also deserves a mention for being blisteringly fast compared to IE9 -- and there's no final version of IE10 for Windows 7 coming any time soon. In large part, this brings me back to the main conclusion of my last post: Windows 8 does some genuinely good things for all-round productivity. But for other, more leisurely pursuits, I don't yet see any compelling reason why the desktop user should upgrade.
