Microsoft suggests disabling ReadyBoost until SP1
Microsoft plans numerous fixes including an update to ReadyBoost

Microsoft officially launched Windows Vista for volume licensing on November 30. The company also simultaneously launched Office 2007 giving Microsoft a 1-2 punch in the realm of operating systems and productivity suites.

"These are game-changing products," said Microsoft CEO Steve Ballmer at the launch. "It’s an incredible step forward for business computing in a year of unprecedented innovation from Microsoft. We expect that more than 200 million people will be using at least one of these products by the end of 2007."

Microsoft followed up with the retail launch of both products two months later on January 30. Both software products were made available in over 70 countries and over 40,000 retail locations.

Windows Vista is not even a year old, but Microsoft is already orchestrating the launch of Service Pack 1 (SP1) Beta 1 for the week of July 16. Many companies will not even touch a new Microsoft operating system until the first service pack is released, so the quick rollout of SP1 isn't totally unexpected.

According to ZDNET's Mary Jo Foley, SP1 will RTM in November after just four months of testing. Microsoft will also release Windows Server 2008 at the same time.

Expected updates/fixes included with SP1 will be a revised Desktop Search, faster file copying and shutdown speeds, support for SD Advanced Direct Memory Access, enhancements to BitLocker Drive Encryption and Extensible Firmware Interface (EFI) support on x64 machines.

There will also be changes made to Windows ReadyBoost. There have been numerous complaints around the web concerning ReadyBoost and resuming from S3/S4 sleep. Sluggish performance on resume can be attributed to numerous writes to 'Readyboost.sfcache' on the ReadyBoost storage device.

According to Microsoft’s Robert Hensing, "[ReadyBoost] uses an AES 128 key that is generated once per OS start (the data in the file on the thumb drive is encrypted with this key) . . . the key isn't persisted anywhere (i.e. it lives in memory only) and so apparently when you sleep / hibernate - the key goes bye bye and thus you need to rebuild your 2GB ReadyBoost cache on your USB disk when you resume again."

Hensing continues, "Vista realizes that it needs to regenerate the ReadyBoost cache as soon as it wakes up and loads the USB drivers and realizes the ReadyBoost drive is plugged in and it starts helpfully doing this as soon as it can . . . ya know - while the OS is trying to page all that memory back into my 2GB of system RAM as well and generally restore the OS to a working state  . . . sigh . . ."

The changes made to ReadyBoost in SP1 will ensure that cache data is reused during S3/S4 sleep so that 'Readyboost.sfcache' is not repopulated on resume.

Could also be anti-virus software. Trend Micro used to have problems when copying compressed files because it would have to expand the file and scan it causing additional performance hit even if the file was already scanned and confirmed virus free.

If we could get away without having to have AV, firewall, malware, and spyware software running all the time well then we would get a nice boost in performance. Probably one of the big reasing a 733mhz x-box can play FarCry but it crawls on a PC with twice the ability.

Hmmm probably not. Probably something to do with the port being optimized poorly for the PC.

It was released for the PC first then ported to the Xbox.

Would it have to do something with the different resolutions between the PC and XBOX?

A 733 - 800 PIII with a Geforce 3 can probably handle the game at 640 x 480 but move to 800 x 600 and it may crawl.*

*I haven't and won't try this out.

Exactly. Who on their PC plays it at 640x480 no AA no AF? I play that game at 1920x1200 8x AA and 16X AF and it purrs on a 8800GTS, it did fine on a 7800GT also. You could today probably run the game at 640x480 with a budget card or even some of the better integrated solutions and a budget CPU. Also, they dumb down things like textures for console versions and implement performance enhancements by taking away things that would scarcely be visible on an analog TV (which the XBox was designed for).

While I have to say this is a little off topic it is also VERY true. I always find it amusing when people tell me how much faster consoles are than computers and its exactly because of this sort of thing.

Back on topic:
As soon as SP1 becomes final and official, I think I will finally make the transition to Vista.

I'm afraid if Microsoft think that rushing out SP1 very early will make those people currently holding-off feel confident to switch, then they are wrong. An early release of SP1 will mean I'll probably hold off until SP2.

It's not like there is anything wrong with XP which Vista could do better (at least for me), and there's a lot which Vista would do worse (especially when it comes to drivers and compatibility with certain apps I need). In a year or so, SP2 should be on its way and by then Vista will probably seem a lot more tempting. As it is, I've got a partition already available for installing Vista, and a copy of Vista RTM ready to install, but I really don't see the point just yet.

Finished the game on a GeForce 2 GTS 32Mb (w a Athlon XP 1.4Ghz, 768Mb Ram) card playing 800x600, there were a couple parts that would consistently crash the game, too much info for the 32Mb video ram was my guess as to why - just had to enter a few cheat codes to bypass the level segments that crashed it.

And yes, the game looked like ass, but hey I wasn't complaining, it played. Q4 played surprisingly well too, except in the areas with more than half-dozen characters on screen at once.

A Geforce 3 should make up for the slower CPU and play the game about the same.
