New Xbox Experience: DVD vs. Hard Disk Face-Off • Page 3

Is it worth installing stuff? We investigate.

Mass Effect

Install Size: 6.8GB

Ever since the concept of installing Xbox 360 games to hard disk was first mooted, the big "what if" has always been just how much better Mass Effect would be were it running from a medium faster than optical disc. The game's infamous for its protracted elevator rides (aka background disc loading), texture pop-in and gameplay glitches seemingly concurrent with DVD reading. Unfortunately of all the games tested in this feature, Mass Effect is the only one I've not really played before at all. Therefore, in the schedule allotted, the best I could do was to play the beginning of the game from both DVD and HDD.

Like Fable II, Mass Effect has tangible advantages running from hard disk, but unfortunately the NXE installation feature isn't the all-powerful Elder Wand required to magically erase Mass Effect's many technical issues. To begin with it's basically the same game with identical performance - texture pop-in doesn't seem so much removed, as relocated. I was unable to quantify this aspect of the game between the two video captures I recorded; when and where the pop-in occurred remained entirely arbitrary between both versions. I'm told that the texture pop-in becomes far more of an issue the further you play the game, so my observations here are far from conclusive - but I can't see running from HDD actually having a detrimental affect, and the advantages are well worth the installation.

First of all, in several occasions during my playtest, it became obvious that the DVD couldn't keep up with the player's progress. This would manifest in on-screen pauses and glitches accompanied by a mechanical form of protest from the DVD drive, at worst resulting in the game momentarily freezing with a 'loading' prompt helpfully explaining what was going on. In the same places, the HDD-installed version proved to be flawless. Unfortunately, there are no differences in the duration of the teeth-grindingly annoying elevator rides - clearly these were hard-coded in as opposed to being measured based on the data rate of the streaming.

So the jury's still out on Mass Effect, and it'll be interesting to see what kinds of improvement you guys who've got the saved games I wish I had see with this release. In the meantime, these meagre loading time observations will have to do...

Initial Loading 25.5 seconds 20.5 seconds

Normandy Quarters 12.5 seconds 10 seconds
Citadel Upper Wards 16 seconds 14 seconds

BioShock/Project Gotham Racing 4/Call of Duty 4

We conclude the gamesy bits with a roundup of measurements on three titles that - for me - typify the average performance gains you're likely to see with the majority of games once they're hosted on your hard disk.

Rapture hard disk around this one.

In common with many games based on Unreal Engine 3 technology, BioShock combines the traditional level-loading with on-the-fly streaming from the DVD drive, and installing the whole game to hard disk produces predictable results.

We see a variable level in improvement in loading times - anything up to 30 per cent - but the actual behind-the-scenes streaming sees no real difference whatsoever. In truth, BioShock never really suffered from the same level of texture pop-in as certain UE3 titles, so these results are hardly surprising.

With Project Gotham Racing 4 and Call of Duty 4, we see similar loading time improvements, although both games don't appear to be streaming much data in on-the-fly, preferring to load all data before gameplay begins.

120GB vs. 20GB HDD

And finally, these tests pit our battle-weary launch vintage 360 20GB drive up against the default Elite 120GB unit. In theory, a newer, unused drive with faster technology, combined with higher data density, spinning at the same speed as the 20GB unit should give tangible advantages, making the upgrade even more attractive. However, as you can see from the tests, at best you gain a couple of seconds advantage over the default drive - in short, the upgrade's worth it if you want to have more than one game available on HDD, but don't expect any really worthwhile speed boost.

In order to show you what 4K gaming actually looks like we needed to build our own platform to supply high quality 4K video for offline viewing. So we did.

Our videos are multi-gigabyte files and we've chosen a high quality provider to ensure fast downloads. However, that bandwidth isn't free and so we charge a small monthly subscription fee of $5.
