Guild Wars 2 (GW2) is one of the most popular MMORPG video games developed by ArenaNet. It is based on the original game engine, but it has been greatly modified. The game engine will now include enhanced graphics and animations with real-time 3D environments, and it also uses an improved physics engine called "Havok".
Though GW2 is one the best MMORPG games, it has its flaws – if the game lags or runs slow on your computer, you're not going to be able to get anywhere on it. GW2 heavily relies on two vital functions of a PC for it to run well - a smooth broadband Internet connection and a reliable PC which meets the following minimum system spcs:
Windows XP Service Pack 2 or better
Intel Core 2 Duo 2.0 GHz, Core i3, AMD Athlon 64 X2 or better
NVIDIA GeForce 7800, ATI Radeon X1800, Intel HD 3000 or better (256MB of video RAM and shader model 3.0 or better)
25 GB available HDD space
Broadband Internet connection
Keyboard and mouse
In case if your system meets the above specs and still runs slow and lags then the issue is down to a part of your PC called the "registry". It is a central database which keeps all the settings and options that your system requires to run, and is what Windows uses to save such details as your desktop wallpaper and your stored passwords. The registry is used thousands of times every time you use your computer, and is continually being used by your software as well. Games like Guild Wars 2 depend heavily on the registry database to assist them recollect settings like your Character name and keyboard layout. If any of these settings are busted, the outcome is that your computer is going to take considerable time to read the files that your GW2 requires to run. This is a huge issue for most Windows based PCs, and is the main reason why GW2 and most other games lag or run slow.
The trick many gamers bring into play to enhance the speed of their Guild Wars 2 or any other game is to repair any corrupted settings from the registry using a good software program. They are very simple to use and if you are able to get a good tool for your computer, it should improve the speed of your system and gameplay considerably.
