How to fix gaming mouse problem in Vista 32/64

I have seen many people saying that  Vista is not suitable for gaming purposes. It is not really true. I have been using vista from  March 2007 and all of my games worked perfectly in it. Vista surely have lots of compatibility issues but most of the problems can be fixed. One of the most serious issues the vista gamers facing is gaming mouse incompatibility. Updating drivers  or firmwire won't help in any case. Serveral top brand gaming mouses such as Razer Lachesis, Razer DeathAdder, Logitech G5, Logitech G9, Microsoft Sidewinder, Microsoft Habu, Cyber Snipa, Steelseries Ikari, etc have similar kind of problems such as macros not working or side button not working in games.

This problem is caused by UAC(User Access Control) component in Vista. UAC is a security component in vista which limit application software to standard user privileges until an administrator authorizes an increase in privilege level. It help to prevent malware programs from gaining system access. Not only malware but all the applications and drivers are affected by this. This is the reason for gaming mouse problem. It can be fixed by disabling UAC as I've explained below.

How to disable UAC?
1. First click on start button and type "msconfig" and press enter. UAC will ask for permission, click on continue.


2. Select Tools tab. In that, select "Disable UAC" and click on Launch button.


3. Finally restart vista to make it work.

Note: If you want to re-enable UAC then do the similar steps and use "Enable UAC" instead of "Disable UAC".

The pointer for a gaming mouse does not move correctly in Windows Vista
This is another commonly seen issue in vista.
You may experience the following problems in Windows Vista when you use a high performance gaming mouse, and you enable the Enhanced Pointer Precision option:
• The pointer does not move correctly when you move the mouse down and to the right side.
• The pointer moves by itself.
• The pointer movement is irregular.

Intel names new chip Core i7

Intel Corp said it plans to sell its new generation of chips for desktop computers under the established Core brand, with the first chips of the new line to be called Core i7.

The microprocessors are based on a design the company has code-named Nehalem and are expected to be in production the last three months of this year. Intel says the new design will deliver both high performance and energy efficiency.


Sporting anywhere between two and eight processors cores, the first chips will integrate a memory controller and come with Intel's QuickPath Interconnect (QPI) which is expected to provides a faster route for the CPU to communicate with system components such as a graphics card.



Some new technologies in Core i7
  • Dynamic scalability, managed cores, threads, cache, interfaces, and power for energy-efficient performance on demand.
  • Design and performance scalability for server, workstation, PC, and mobile demands with support for 2-8+ cores and up to 16+ threads with simultaneous multi-threading (SMT), and scalable cache sizes, system interconnects, and integrated memory controllers.
  • Simultaneous multi-threading brings high-performance applications into mainstream computing with 1-16+ threads optimized for a new generation multi-core processor architecture.
  • Scalable shared memory of Intel QuickPath technology features memory distributed to each processor with integrated memory controllers and high-speed point-to-point interconnects to unleash the performance of next-generation Intel® multi-core processors.
  • Multi-level shared cache improves performance and efficiency by reducing latency to frequently used data.
Intel is expected to add other identifiers to the Core i7 name as it launches products in the range. It is also expected to identify its high-end "Extreme Edition" parts with a black logo. Intel's Core i7 will be available in market by Q4 2008. Intel is also expected to release its laptop range of processors, based on the Nehalem, in the second half of 2009.

Samsung to ship ultra fast 256GB SSD Drive



Samsung plans to launch a flash memory based solid state disk(SSD) drive this year that has a 256GB capacity and a high speed SATA II interface. The drive's dimension match those of a standard 2.5 inch hard disk drive; it's designed to be a drop-in replacement for a laptop hard drive.

Solid state disk drives use a flash memory chips in place of spinning magnetic disks that hard disk drives use. The chips make the drives sturdier and faster but the per gigabyte cost is much higher too.

Samsung's is the second recently announced 256GB SSD drive. The other from US based Super Talent, is thicker than Samsung's, at 12.5 millimeters compared to Samsung's 9.5millimeters. That drive has a SATA I interface with read speed of 65mbps(megabits per second) and write speed of 50mbps. Samsung's SSD drive has a read speed of 200mbps and a sequential write speed of 160mbps.


Rather than use costly single-level cell (SLC) technology, the company has managed to develop a multi-level cell (MLC) storage drive that transfers as quickly as the best SLC storage while costing much less to produce than past SSDs. Improvements to the storage controller have also extended the longevity to as long as SLC drives, giving the 256GB drive longevity as good or better than some rotating hard disks. Power consumption is also exceptionally low at 0.9 watts in active mode.

In addition, the drive offers a sophisticated data encryption process that prevents data stored on the SSD from being accessed in an unauthorized manner, even after the SSD is removed from the PC.

Once introduced, the Samsung's 256GB SSD will mark the largest capacity SSD from the global market leader in SSD sales, effectively eliminating density as a barrier to SSD adoption in the consumer space. Samsung expects its new drive to be sampling for computer manufacturers by September and shipping to those clients by the end of the year; this applies to both a 2.5-inch drive for more traditional notebooks and a 1.8-inch drive for ultraportables and other much smaller devices. Costs haven't yet been announced.

Tweaking maximum half-open connection limit in XP and Vista

Microsoft has set limits for number of concurrent TCP connection attemps in WIndows, in order to protect users from malicious bots, spyware etc. Normal users will not face any problems. But the p2p applications such as BitTorrent(uTorrent, BitComent, Azureus, etc), Limewire, eMule, Sopcast, TVants and some multiplayer games (mainly P2P games) may face some slow download and upload speed due to this limit.

Registry tweaks doesn't work. They set those limits in TCPIP.SYS and other system files which need to be patched. Following explains how to patch your Windows XP and Windows Vista versions.

Windows XP
Original Windows XP & XP SP1 doesn't have any limits. But since XP SP2, only 10 concurrent TCP connections are possible.
Each time your computer tries to establish more than 10 half-open connection, a system event will be logged in Windows. It looks something like this:
"EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts"
Access the event viewer by Start / Control Panel / Administrative Tools / Event Viewer / System. Sort by Event and scroll down to 4226.

How to fix connection limit in windows xp sp2 and sp3?
It is very simple. First you download Event ID 4226 Patcher version 2.23d. Extract the contents and run ExID4226Patch.exe.

In default, it will set the limit to 50. But you can change the limit to any number you want. for eg: 1000.



Windows Vista
Windows Vista have different limit for different Vista edition. For eg, Home Basic has maximum limit of 2 and Vista Ultimate have maximum limit of 25 per second.

Go to Control Panel>Administrative Tools>Event Viewer. You could see "EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts" under System log.


How to fix connection limit in vista?
Vista have enhanced security. So tweaking limit is not easy as in xp.

First you need to find out which version of tcpip.sys you have. Go to \Windows\System32\drivers folder, right click on tcpip.sys and select “Properties”, and the version info will be listed in “Details” pane.

Download the patch for your tcpip.sys version
Unpack and extract the content of the archive. Follow the instructions in the README.TXT file that comes with the patch. For running InstallPatch32.bat (for x86 system) or InstallPatch64.bat (for x64 system), administrator rights elevation required. Right click on command prompt(start>programs>accessories) and select "Run as Administrator". Execute the bat files using this command prompt.

IMPORTANT
Vista (32/64) requires all drivers to be digitally signed. It will fail to boot up or block driver from loading.

One way of to solve this issue is by pressing F8 during initial boot of the Windows Vista system, and then select Disable Driver Signature Enforcement in the “Advanced Boot Options” menu. However, you have to repetitively do the same process again and again on every system reboot.

But you can automate this process using ReadyDriver Plus. You can download it from here. It will ask for /BOOT path(choose drive which vista is installed). If you have dual boot, you need to choose number of keystrokes. For eg: if you have windows xp under windows vista in boot menu, you need to select 2 keystrokes.

The plans are to have characters and movement reminiscent of the animation, and high-intensity battles.

During each battle, find conditions to create new dramatic scenes. After the battles, watch a unique story unfold each time you play. There is also a stronger element of offense and defense, due to added energy saving and fighting techniques.

Graphics is far better than all the other DBZ games. The character models, skins and special effects were excellent. The sound effects and voice were also excellent. Voice sounded like the original cast from DragonBallz.

Characters
Even though Burst Limit have limited number of characters, each fighters have their own set of characteristics and abilities which reflect the real characters of anime series. Burst Limit has more variety in its tiers than most of the previous Dragon Ball Z games. Most of the characters are unlocked during the game after completing particular stage.
The following characters are playable in the game:
  • Goku
  • Gohan
  • Piccolo
  • Krillin
  • Yamcha
  • Tien
  • Trunks
  • Vegeta
  • Nappa
  • Raditz

  • Frieza
  • Captain Ginyu
  • Recoome
  • Cell
  • Android 16
  • Android 17
  • Android 18
  • Bardock
  • Broly

Features
  • Online Feature - Competition grows with the ability to play online in both the co-op and vs. modes.
  • Unique DBZ Story -During each battle, find conditions to create new scenes and watch a unique story unfold at the end of each game.
  • Higher Quality Gaming - Experience visuals and movement reminiscent of the anime due to Z3 shading technology and detailed effects.
  • High Intensity battles - Increased speed of charge and release on the field, free movement around the field, and increased speed and power of attacks.
