Game Booster is an easy-to-use program that shuts down unnecessary system processes in order to improve the performance of resource-thirsty games. With an intuitive interface that makes it easy to switch between gaming mode and normal mode, Game Booster is a simple but powerful program.

Game Booster's interface is basic, with a list of 24 noncritical processes that can be shut down during gaming. Check boxes allow users to select specific processes. It is true that you have to take a leap of faith with some of these; if you're not extremely computer savvy, you may have no idea what it is that you're shutting down. We can say that our system suffered no ill effects from temporarily disabling all of the listed processes, and the program quickly started them again when we switched back to normal mode. We do wish that the program came with a Help file that went into detail about this issue, though. In addition to disabling unnecessary system processes, Game Booster offers a game defragmenter that specifically defragments the game directories, allowing a given game to start and run more quickly. Overall, we found Game Booster to be both easy to use and effective. We noticed a significant difference in game performance when using gaming mode, and we think this is a great choice for users who need to optimize their systems for gameplay.

Game Booster is free. It installs and uninstalls without issues. We recommend this program to all users.

Great for loading adware/malware onto your PC!
Ulster MongooseNovember 26, 2014
Pros
i swear by the beard of almighty Zeus that this fine piece of software no other "gamer booster" could not load any more annoying adware and other malware on to your pc than 'Razer Game Booster', i mean, i almost had to reinstall windows completely! if you want to be pissed off to the point where you want to physically harm the people you put this together then well.. look no further.
Cons
Well if i had to choose one this wrong with this... neurowise and Advance Elite are fucking soul crushing sneaky adware programs and all but they could do more i feel.
Summary
if you hate your pc and yourself, download this and the 'great' bundled programs that come with it
Program is very easy to use.
IronbruteNovember 4, 2014
Pros
1. Simple. 2. You can start recording videos by pressing ctrl + alt + V 3. easy upload access to your youtube channel. 4. no lag at all 5. Works well for windows 7
Cons
I have yet to stumble upon any cons yet. Its a free program and is still in beta. I'm sure there might be some bugs in the program but have yet to have that issue.
Summary
Fake system tweaks.
jasont4cOctober 29, 2014

Registry changes for the tweaks are fake.

Constipated02March 1, 2014
Pros
-Sort of easy to use interface -Constant freezes are fun
Cons
-Random FPS drops I was playing GMOD, and there were 2 - 3 props on screen, and it went from 15 to 3. -Crappy FPS Black Ops runs at 30 - 50 FPS now that I've deleted Razer. It used to be at most 20. -Craps on your computer when you load it up -Another gr-e-e-e-e-a-a-t product from Razer Inc. -Only usable online -Requires a log-in
Summary
Honestly, you'd be better off not using this at all. It doesn't boost games, hell, it even LOWERS your FPS. What I recommend? GET A COMPUTER THAT CAN HANDLE GAMES. Peace. 1 / 10000000 Updated on Mar 14, 2014wat srsly wat
FPS drops - Shit
Razer_HaterDecember 21, 2013
Pros
looks nice
Cons
Tried it on games and got an fps drop of 60-70 average to a 20-30 average even after uninstalling it.
Summary
Dont recommend makes games run horribly
Deleted everything from my hard drive.
ComputerUser123December 19, 2013
Pros
It showed me when driver updates were available before I updated Game Booster.
Cons
After opening the program, I was prompted that an update was available. I updated the program and it deleted all my files on that hard drive and created a bunch of junk folders as well. Deleted all the games that it was supposed to boost.
Summary
CREATE A SYSTEM RESTORE POINT BEFORE INSTALLING. THIS PROGRAM LITERALLY DELETED EVERY PROGRAM ON MY HARD DRIVE. Luckily it was my secondary hard drive, but this is still a major issue with the program. Terrible coding and poor testing before an update is pushed and now I have to spend hours fixing everything this program messed up.
Really good
Windows78December 2, 2013
Pros
-Can record and take screenshots of games -Easy to use -Really good
Cons
-Requires .NET Framework 4.0 -I need always to log in which is very annoying
Summary
Game booster on steriods
super14man1November 22, 2013
Pros
If you used game booster before you know how to use this software and it is 100 percent free
Cons
have to be online at all times to use this software. Entering an username and password each time using the program is annoying.
Summary
Great product!
stoupedogOctober 16, 2013
Pros
Nice, sleek design Fast to boost and unboost games Lots of other features (e.g defrag and screen recording)
Cons
Slightly slow to start up.
Summary
Overall, I think this is a very good product from Razer, but you only really need it if you have games on your computer that run badly. In conclusion, if you have a top of the line gaming computer, you probably don't need this, but if you have to change your video settings to low to reach 30fps in games, then I would recommend this product for you.
