Even though the product isn't out of beta yet, reviews have started to roll out from the tech enthusiast community. Yesterday, ExtremeTech's Loyd Case took a peek at the latest beta of TweakVista, Stardock's tool for squeezing every last ounce of performance out of your Windows Vista installation.
It's a fairly detailed review, taking a look at both the application's current strengths (great interface, easy access to a lot of hidden information) as well as a few weaknesses (needs more in-depth information). Overall, they gave the beta version a 8/10 and an "ExtremeTech Approved" seal. Throughout the review they make sure to be clear the application is still in testing, so issues they noticed could be addressed before final release later this year.
If you're curious about the program and want to read up on it a bit, this review is a great introduction to TweakVista from an outside point of view.
